PROBLEM:
CANNOT BOOT TO STOCK NC 1.2 ROM
Whenever I try to boot, with microSD card inserted, I boot to ClockworkModRecovery. Inside CWM Recovery Console, version states it's 3.0.2.8. In ROM Manager, it says it's 3.2.0.1. (Because at some point in time, I tried to update it through the Rom Manager. It did say that it was updated successfully, but whenever I boot to CWM, it still says 3.0.2.8.
Whenever I try to boot, without microSD card inserted, I boot to CM7 Nightly Build 97. What appears is a green cyanogenmod logo followed by a cyan-colored "loading..." below, then a flash, then straight to the CM7 boot screen (the blue android on skateboard).
FACTS:
[*]I'm currently running CM7 Nighty Build 97 along with Dalingrin's OC Kernel set at 1200MHz (Which made it a lot responsive and faster, thanks to Dalingrin! ) at my NC.
[*]I have to remove the microSD in order to boot to CM7. If I don't remove the microSD, it goes to CWM.
[*]I don't know, I don't have, and I'm not planning to install --- ADB.
[*]My microSD is a SAMSUNG 16GB Class 2 microSD card--at least, that's what it says on the card--which came from a Red Sandisk packaging. Weird, I know. Just putting all the info here, maybe it'll help solve the problem.
[*]My NC came with a green dot on it's packaging. I was told it has something to do with the partitioning of it's internal memory, but from what I can see, my NC has 5GB of internal memory capacity.
THE STORY:
Before, I was running CM7 7.0.3 (Stable) on my nook.
With microSD inserted, I boot to CM7. What happens is there would be a flashing, cyan 'a n d r o i d . . .' text at the left side of the screen. Afterwards, the CM7 logo appears and boots to CM7.
With microSD removed, I boot to STOCK NC 1.2 ROM. What happens is a "Read Forever" logo would appear, then a colored 'n' logo, then 'nook color' logo, then home screen.
Then I found out that there's a way to overclock the NC but it requires installing nightly builds. At first, I was a bit skeptical of installing a non-stable build, but when I tried it out, man was I amazed. My NC got a lot faster. I installed the CM7 Nightly Build 97. But then, I found out that I couldn't boot to the STOCK NC 1.2 ROM anymore.
HOW I DID IT:
I followed this instruction to install CWM:
hxxp://mrm3.net/nook-color-updated-clockwork-recovery-bootable-sd/*
NOTE: I picked the 16GB link under "Clockwork Recovery v3.0.2.8-Old Nook Colors(not blue dot)" category since I have a 16GB microSD card and the other category "Clockwork Recovery v3.2.0.1-For new blue dot Nook Colors and Old Nooks" does not have a link for 16GB, only 1GB.
Then I followed this guide to install CM7 Nightly Build 97:
hxxp://mrm3.net/nook-color-how-to-install-cyanogenmod-nightlies/*
NOTE: I ignored the instruction "Only install if when you boot your nook it DOES NOT SAY READ FOREVER" and proceeded to installing the updated U-Boot 1.2 simply because I overlooked it at that time (could this be causing the problem?)
And this to overclock my NC:
hxxp://mrm3.net/nook-color-overclock-guide/*
NOTE: I ignored the fact that it says "Install 'update-CM7-dalingrin-OC-emmc-060911.zip'. " even though I was a bit skeptical. I did got skeptical a bit because I thought I should install instead the sd update instead of the emmc. But I proceeded anyway. (Could this be it?)
Can someone please identify what I've done wrong? Or can someone please give me a tutorial to fix it? Or at least point me to a tutorial that will fix the problem. I've been trying to find a way to fix it by myself by reading forums and blogs and stuff but I can't seem to find anything. I'm a noob, but I do know how to follow simple instructions. I'd really appreciate it if you can help me. :'(
*replace 'xx' to 'tt' to view the link.
You haven't done anything wrong, but you did get rid of your previous setup. You turned your SD card into a CWR bootable card, then installed CM7 to your internal memory. By doing this, you erased your stock 1.2 and replaced it with CM7. To get your SD card to stop booting to CWR, you can simply format the card. This will remove the boot files and it becomes a standard memory card once again. If you want your stock 1.2 back, there are threads here that explain how to revert back to stock. You might need that bootable SD card, however, so wait until you decide what you want to do before formatting the card.
Unless you have some reason to want your stock 1.2 back, I would suggest you just stick with what you have. It is what most of us are running.

Thanks for that. I was sure I didn't do anything wrong.
My reason for wanting to get access to my stock ROM is for me to 'Archive' my epubs. I have like a million of them, and I do read a lot. I cant find a good app to view epubs just like the stock B&N NC 1.2 reader... so if I archive those epubs, I'd be able to view them through the nook for android app. And yup, I've tried putting the epubs in the nook directory, it's still not reading it. That's basically it. If you guys can find a better way to view epubs like the stock B&N, I'm happy. Any ideas?
I'm hoping to try Phiremod as well in the near future, just so I can get a feel of which ROMs are the best. I've seen people running a ROM that still has the original 'Nook Color' status bar at the bottom and a dock bar on the side.
See it here: hxxp://w w w.youtube.com/watch?v=8d7ncguNjrE*
I think it's cool. If that build can run all apps in my CM7 nightly (I recently updated to Build 100), and also if that can be overclocked to at least 1.2GHz, I'll be so happy.
Please comment on all your ideas!!!
up up up up up up.
Persistent, aren't you.
There are lots of free apps that can read epub files. I downloaded the free epub of 'Phantom of the Opera' from some random web site, then looked in the Market for an 'epub reader'. One called 'FB Reader' was one of the first results. Opened the book fine, had lots of user-changable options and settings. Lots of other such apps available. Did this all in about 3 minutes using only my Nook with CM7 installed to internal memory. Took me longer to type out this post.
Well, i'm a noob to this forum, and to doing ANY rooting/flashing. There, thats out in the open XD
Heres the specs:
CM7 7.0.3 Stable
Nook Color (Blue Dot)
ADW Launcher
Onto the issue! I have searched ENDLESSLY for a solution to this, but have come up short. Nearly everytime I power off/on or reboot the Nook, all my widgets show "Problem Loading Widget". The ONLY way to get them running again is deleting and replacing them again on the screen.
Let me explain some things I have done and hopefully we can figure this out. I am assuming, that it may be due to me performing this - http://forum.xda-developers.com/showthread.php?t=1034939. Basically what that does is take the unused eMMC from the NC and tag it as the SDCard. The reason for doing that is because I don't have any ACTUAL decent sized SD cards and figured why not use the 5GB thats avail and unused on the Nook, and "simulate" it as being a 5GB SD card for apps and whatever else.
Nearly every post I have read says it has to do with having the apps for the widgets on the SD Card. Well, they're not, they're on internal memory. AND, if I do move them to my "simulated" SD Card, they don't even come up in the widget list, so that clears that option.
Also, since I had a Blue Dot Nook, I performed this - http://forum.xda-developers.com/showthread.php?t=1094371 and partitioned to the old style NC.
I have tried and tried to find out where the apps, if stored "internally", actually are. I cannot for the life of me find them, other than the default Google Apps in /system/app, as well as the ones I have downloaded on the "simulated" SD card under /mnt/asec & /mnt/sdcard/android.secure.
Also, when I plug the NC into my PC, I see whatever is on my "simulated" 5GB SD card (which is really the eMMC of the device). Is it possible to view the root of the device at all to see ALL the files/folders on it?
If someone can solve this, I will be eternally grateful, in a totally non gay way atleast. THANKS!
Hey there....
I'm new to the NookColor and rooting/flashing Android devices, too (though, I did run Linux on my Palm Tungsten T3, back in the day). I probably only partially understand your woes, but it seems to me that your problem stems from the faking microSD thing. Maybe it's not so much that Android wants to put something in the SD, as much as it's confused, when it probes for orthodoxy. I understand the want to use the internal memory, instead of buying a mSD, honestly.
Again, I'm totally new to this, but reading your post and many other posts in the last 48 hours, I think I might have a valid solution: start over. If I were you, I'd do the following, which, incidentally, is very much what I'm in the process of doing, too. I'm starting from "blue dot" scratch with two mSD's (2GB & 8GB) in-hand, though. By the way, and if it's any help to you, I bought my Class 4 SanDisk 8GB mSD at Office Depot yesterday for around $15 (on sale?).
1. Buy a microSD card.
2. Image the card with ClockworkMod.
3. Install TitaniumBackup Free.
4. Backup all of your apps/stuff to the microSD card with TitaniumBackup.
5. Save an image of your current setup with ClockworkMod (booting from mSD, backing up to mSD)
6. Repartition to the old (pre-"blue-dot") scheme, again, using the first mrm3.net link below as a guide.
7. Install the latest CM7 Nightly for "encore"...
8. Save an image of your current setup with ClockworkMod (booting from mSD, backing up to mSD)
9. Install TitaniumBackup Free.
10. Restore all of your apps to the microSD card with TitaniumBackup.
(Of course, I'm assuming a lot of things... I guess I'm just thinking aloud... Maybe some of this is of some use to you. Good luck!)

p.s.... I had a few links I was going to share, but I'm not allowed to share external links until after my 8th post (and I understand why that's a rule)... lol..
There seems to be plenty of threads about these things around here. I just don't have them right now..
Thank you vulariter! It'd be great if when you finish getting everything set up, letting me know how it works out for you. I know people have been having some pretty weird things happening with the blue dot Nooks. Appreciate the info.
I"m happy to report that my internal CM7 Nightly install went well. I chose to go with a 2 GB apps / 4 GB media internal partitioning scheme. I like breathing room, on both sides..lol.. I also like doing things the difficult way, sometimes.. (just being honest)...
Minus the unnecessary convolution of my rooting the stock OS, 50+ complex character WPA2 key, static IP WIFI network, and email address fiasco, here's basically what I did. Again, I'd love to share the external links, but I don't think it will let me do so.
Oh, and always check MD5 sums on the files you download, wherever possible. Corruption in these files will surely eat your Nook alive, at least a little. lol.. Yes, be very scared of that.
Also, don't forget to backup your ClockworkMod backups to a better medium than the microSD card. I used 7zip to archive them on my laptop's internal drive. A cloud backup of them would probably be better (e.g. Dropbox). Just remember, you're putting potentially personal info out there, wherever you put these backups.
Thanks to all the people who figured this stuff out (see the links / websites below, to give them credit).
Bought a NookColor at my local B&N. (I later read about the "blue dot" thing and realized mine had the "blue dot" on the back of the box.)
SIDE NOTE: My understanding is that the "blue dot" signifies only a few important things. 1. a 5 GB apps / 1 GB media partitioning scheme... 2. U-Boot 1.2, with the "Read Forever" logo..... 3. Maybe an unlocking of a few more cylinders (about 250 MB)??? I've only read a little on this..... 4. Maybe a different chip revision or two, inside.
Bought a SanDisk Class 4 (class 6 would have been better) 8GB microSD card.
Located my microSD to SD adapter, which is a priceless item to me.
Located my USB many-in-one card reader, because my Lenovo R61's internal SD reader is unstable.
Located my 2GB class ? microSD card, which I once used in my old LG env2.
Connected my USB card reader to my laptop.
Inserted the 2GB mSD into my USB card reader.
Copied all of my old music, etc, on my 2GB microSD to a directory on my laptop for posterity.
Downloaded the latest version of Win32DiskImager. (Link 1)
Downloaded the latest version of ClockworkMod 2GB SD image. (Link 1)
Imaged my 2GB mSD with the ClockworkMod image.
Created "clockworkmod" and "clockworkmod\backup" directories, inside of the 2 GB mSD (whose disk label is now "boot").
Downloaded the "Custom: 2GB for Apps and 4GB for Media" partitioning file from mrm3.net and placed it in the root directory of my 2 GB mSD.
Downloaded the "Mandatory Data Format File" from mrm3.net and placed it in the root directory of my 2 GB mSD.
Downloaded the latest CM7 "encore" Nightly from cyanogenmod.com and placed it in the root directory of my 2 GB mSD.
Downloaded the latest "encore" Gapps from mrm3.net and placed it in the root directory of my 2 GB mSD.
Confirmed my Gmail and Youtube accounts were linked. This is also the same address which I'm using for my B&N account.
SIDE NOTE: I had to change my B&N account's non-Gmail email address to align my email addresses. I think this may have caused a problem with my obtained-at-Nook-purchase B&N Membership Card, because it no longer works... (I've contacted them about it...and their answer is unsatisfactory. Beware!)
Unboxed my NookColor and began charging it, via the wall plug.
Booted my stock NookColor, signed into my WIFI network and registered my device to my Gmail email address.
Played around with the stock OS and Nook apps, because I'll probably never ever see them again.. The Crossword game was awesome! I didn't allow myself to become attached to their reading apps, to be honest..lol.. (I would have probably been attached, had I not been proactive in my "hacking".)
Powered off my NookColor.
Inserted the 2 GB mSD into my NookColor.
Booted my NookColor into ClockworkMod.
Saved a backup of the stock system to the "backup" directory I created earlier.
Followed the instructions at mrm3.net to repartition my NookColor (rebooting, as directed).
Removed the 2 GB mSD card.
Rebooted again, allowing the Nook to recover from the repartitioning. I did not reregister the device in this step. I just waited for the woman's face to appear and shut it down.
Inserted the 2 GB mSD card.
Booted my NookColor into ClockworkMod.
Saved a backup of the NEWLY PARTITIONED stock system to the "backup" directory I created earlier.
I followed the mrm3.net CM7 Nook Nightlies instructions, but I'll paraphrase here. (Definitely seek this article out, and don't take my word for it.)
Still in ClockworkMod, I reformatted the "data", "system",and "cache"partitions.
Used "install from zip" to install "cm_encore_full-xx.zip"
Used "install from zip" to install "Nook_Color_Google_Apps.zip"
This may be a good time to obtain another backup, if you're paranoid. I did not and wasn't...
Removed the 2 GB mSD card.
Rebooted again, allowing CM7 to do its thing.
Signed into my WIFI network, using the menus.
Signed into the Google Market, selecting all of the Gapps, when prompted. (I figure I can uninstall them, if I find them totally useless.) (e.g. Facebook
app, since I quit it..lol)
Inserted my 8 GB mSD card in the NookColor for the first time and formatted it, from within CM7. I could have made a Win32DiskImage image of the 2 GB ClockworkMod mSD, wiped it out and formatted it for general use, but I like having my own data (media files / apps) separate from my "live recovery environment(s)." Point being, I could have gotten by with just a single mSD card, as tiny as 2 GB and the cheapest class, but I splurged, because I want to keep some music and things on tap, wherever I go.
Rejoiced in the open source goodness.
This would another good time to obtain another backup. I should go do that right now..
Please keep in mind that I might be taking some things for granted. My mind has been altered by being a *NIX System Administrator...
Good luck and let me know if you have any questions.

Great stuff V! So this is what I have decided to do. I will keep my current system until the next stable version of CM is released. Once that happens, i'll go ahead and repartition, reformat, and of course reinstall following all of the proper procedures that i'm too lazy to write out here.
The only other issue I was having with my Nook is that it wasnt recognizing when an SD card was plugged in. I thought it may have been CM7, so I flashed back to the stock OS, and it still wouldnt recognize it plugged in. However, if I have the SD card plugged in, and reboot, it shows the SD card mounted fine. I need to do a check to make sure I can read/write to it, but i'm assuming it will be no problem if it sees it fine. If I were to remove the card, it would not say that the card is unplugged, so theres no instant feedback; it requires a reboot every time to notice if the card is plugged in or not. For me, all I need is it to be recognized and be accessible, as its not like I am going to be taking it out all the time, it will be in there pretty much for good.
I just bought a Nook Color for my girl and wanna root and install a costum Rom...since this is my first time doing this to a nook color (i have done this to my G1,Vibrant and Asus transformer) i wonder what is the most stable Rom?
should i go with Cm7 or Honeycomb?
Keep in mind that i'm looking for stable Rom...i don't want to get my girl mad at me..
Thanks in Advance..
Get a microSD card, and install CM7 onto that. You protect the B&N system, so you won't void the warranty. The entire OS and apps sit on the SD card. The Nook will attempt to boot to the SD card first, so you're golden. Any time you want to be back in the B&N mode - just pull the SD card. No need to root or anything.
Go here for the easy-to-read steps on how to make it happen:
http://quinxy.com/2011/04/01/comple...on-the-nook-color/comment-page-3/#comment-944
Even if you were to mess things up you can always restore the stock rom because it boots from the SD card. That's what's so awesome. I would also agree with cm7. There is a sticky in the apps thread that has a good start on what apps you should download first. Some are paid and some are free. Have fun!
I totally recommend Racks11479's Phiremod/Honeycomb dualboot MicroSD image. It automatically boots into Phiremod (CM7 variant) but also gives you the option to boot into Honeycomb if you want to play with that and an option to boot into stock Nook Color software without taking the MicroSD out. Very nice. Also, if you're worried about stability I highly recommend getting a class 4 Sandisk card to run it off of. If you read through some of the forums this seems to be the best card for running ROMS smoothly. You can find the Phiremod/Honeycomb image here: http://forum.xda-developers.com/showthread.php?t=1045018
Good luck!
And first thing make sure you have a SanDsik microSD card.
It can be a 4/8/16 gb class 2/4 card.
There are a lot of nookers who start out with the wrong card and have a lot of problems later on, not to mention waste of money for those high class cards.
Again good luck.
Echo everything that's been said in this thread.
You have all the right answers posted to get your feet wet without worry.
If you don't want to use the (more experimental) honeycomb on the sd install, just ignore it when you boot it and it goes to the more stable phiremod version of CM7 by default.
The memory card advice is no joke. If you get a whole mess of force-close issues running the rom recommended above from an sd install, it's either a bad download, bad flash, or (90% likely) you need the right memory card.
My sig has the link to the thread if you want to know why SanDisk.
Ok My wife bought me a nook color and I'd like to make it into a tablet. I found a video on youtube that has it running cm7 on a micro SD card but then then runs the stock NC software so as to not void the warranty.
I've tried reading the nook devs, and multiple how to's but feel a bit lost. Can someone point me to
1) step by step instructions even an idiot can follow
2) a link to the different mods and how they are different
3) where these mods are found.
I'd like a way to do this using free software. One place i found to just buy the mod on an SD card and just install it. One other place gave some instruction but needed software that had to be bought (unzippers or something along that line).
thanks for any information I'm feeling a bit overwhelmed..

I started my NC journey by reading some good, but outdated, guide on how to do root and flash custom ROM to the NC. It took me some time to find the correct program to use.
manualnooter: http://forum.xda-developers.com/showthread.php?t=1054027
This post has a rather detailed instruction. Note that you will be installing a custom ROM onto NC and will void warranty... but you can also flash the stock ROM back to the NC in case you need to use that warranty so you don't really lose much.
I forgot which ROM the manualnooter procedure would install, but I think the current most popular and stable ROM is cyanogenmod 7.
Unfortunately the entire procedure will take beginners more than 10 hours to have a grasp on how to do things and maybe poking around and see why some things work that way.
Welcome!
I've personally installed CM7 to emmc (internal memory) using these steps:
http://forum.xda-developers.com/showpost.php?p=11452450&postcount=19
I was also using the microSD card method, and the steps below are good to follow:
http://forum.xda-developers.com/showthread.php?t=1000957
I would recommend using the latest nightly vs a labeled "stable" release. The nightlies have a lot of improvements and are in fact very stable these days. The only thing you'll need is a microSD card, a card reader, and a little bit of patience. It's really not hard, but just make sure to follow all of the steps. If you have any more questions, feel free to ask or search previous threads
I was considering a nightly build.. the nightly builds I need to find the encore build right? (wonder why we call these units encore). Secondly I was wondering if theres an option out there that allows a plain version of gingerbread without the cm7 markation all over the place. Is there functionality in the CM7 builds that I wouldn't get with a pure gingerbread build?
Yeah - encore is the codename for the Nook Color. I think it came from the initials NC....encore. You can always find them at
http://download.cyanogenmod.com/?device=encore
I'm actually not sure if there is a pure gingerbread rom out there. CM7 is based on the official release of GB, and adds some nice things for the nook -- one big one is the honeycomb style soft keys at the bottom since the NC doesn't have the normal android hardware keys.
For newbie, I strongly recommend installing and running CM7 off the uSD first.
Play with it for a while, get used to it, familiar with it while spending more time reading threads/posts in here then thinking about switching it to eMMC or rooted NC later.
Installing and running off uSD are much more simple and easier.
The requirement is: a good (SanDisk class 4 reported as very good) uSD, 8GB or 16GB.
Then follow this: http://forum.xda-developers.com/showthread.php?t=1000957
Cyanogen has this quirky little tradition of naming the software release after the original code name of the device. The Nook Color was code named "Project Encore" (http://www.droiddog.com/android-blog/2010/10/nook-color-likely-dropping-this-week-image-leaked/) by the developers, so the NC is the Encore in CM7. (Similarly, my old Motorola Cliq is called "Morrison" and my T-Mobile G2 is called "Vision")
And Stock Gingerbread doesn't have a number of things which are very useful for Tablets, such as the taskbar "soft buttons" for back, search, home, and menu, as well as the ability to put the taskbar on the bottom, and adjust the lock screen as you see fit. CM7 has all of these, plus the ever popular "much, much more!" The CM7 developers and mods have really outdone themselves and made the Nook Color a massively useful device.

+1 This.
Follow the instructions in that link and you should have a working microSD CM7 installation. 3 things to add to those instructions though:
1.) Try using Win32DiskImager instead of WinImage. People have had problems writing the image with WinImage. The only problem I've seen reported with Win32DiskImager is that sometimes you cannot create a good usable image of a disk greater than 4GB.
2.) If you are looking for a good usable card, get this one. It includes a good USB microSD reader to use when writing the image.
3.) This one is optional. The default SD card image writes an approximately 120MB boot partition to the microSD. With the latest nightly releases of CM7 you can run into issues if you are trying to install both CM7 and gapps at the same time. It is recommended to resize the initial partition upwards in size. Some folks put it over a GB but in my mind a few hundred MB should be fine. The most popular tool to do this with is EASUS Partition Master. I haven't personally done this since it is something that has to be done before the initial install and I had mine up and running before running into this problem.

oI bought a microSD from merit line. Its an ADATA BRAND 16GB CLASS 10. it had good reviews and some places I read to stay with above a class 6 or better. I hope this doesn't cause a problem or my wife will be upset... LOL
I was watching a video on youtube about this process and they mentioned not having all the memory on the microSD available due to the partitions. they used the same partition manager to maximize the storage on the card. Will this be needed or does something happen automatically to use make all the uSD card usable?
With that brand, with that speed, keep all of your fingers crossed and prayed.
And after few weeks of enjoy the CM7, if you start seeing weird things, you then can start blaming the uSD.
does it matter what version software i start with? I've been reading around and see everything from making sure that your on 1.0.1 to 1.3? I'm lost?
Also since I'm wanting to do this all on the MicroSD then this may not be an issue but I've heard some say also to log on first and make sure I sign in with barnes and noble before doing anything. is that important or not?
Lastly. does rooting or anything leave a permanent record in turn voiding warranty or can it be taken back so the factory doesn't know.
Rooting does not leave any records. All you need is to return to factory stock before sending in for warranty
ok I've tried the version 1.3 over and over and each time I get the same problem. after reboot it comes to the blue android on a skateboard it it just keeps running in circles. it will go black occasionally but then right back to the android on the skate board.. what might I have done wrong?
I used the installer in verygreens 1.3 posts and cm_encore_full-209 nightly build

Lets test that card and make sure it's gonna work. Go here and get Crystal Disk Mark. Install it and plug your microSD card into your computer. Run the default tests and post them here. We're looking for the 4k read/write speeds in particular. If they aren't around 1.0 then you're likely to have a problem running CM7 off the card.
My suspicion is that since its a Class 10 card it's optimized for large block writes and not small block writes. Card manufacturers will trade off small block write speed to get the higher class ratings instead of going for overall speed. SanDisk seems to be the exception to this in that they do not tweak their cards to get the high speeds which why they're the recommended card for SD install of CM7.

[Q] Chronic "Unexpected Lack of Boot Partition on the SD card! Please Report"
Hi,
First let me say - YES, i have searched all of the forums here (and a number of other sites) and seem to have tried almost every option.
I have Chronic "Unexpected Lack of Boot Partition on the SD card! Please Report" problems. The farthest I get guaranteed is the cyanogenmod boot and menu (if I try and bring it up). I'm simply trying to get the SD card with cm7 to boot reliably and not eventually loose the boot partition.
Off and on since spring I was able to burn a CM7 image (verygreen's size agnostic, and one or two others I have since lost track of) to a SD card; have had it boot to cm7 and it work for awhile - but then eventual degraded into the no partition found error. the majority of the time it just doesn't work and results in that annoying purple black screen.
When it does work, it only works for awhile and then the boot partition can't be found; a few very small 3 of times - if I copied a new update it woke back up ad worked for a couple of reboots then lost the partition again.
Anybody got time to take pity on my melted brain and take a few guesses?
Clearly I'm not only missing something - but as things have gotten worse, am now missing more (if that is possible) as I'm going backwards to see why it no longer works at all.
At this point wrong has happened so often, I'm just lost on what even worked way back when I started.
I'm trying to backtrack to where it at least worked a little for a few days...but noob world is decaying into worse world.
I tried a couple of other, older processes and a multiboot menu one that seemed promising (plus could handle the new naming conventions for 7.2 CM7); but that one never even got past the missing boot partition.
I have tried approx 10 2gb SDCards, Sandisk, Kingston, Unknown; Class 4 and mixed.
I have tried 3 8GB SD Cards, Sandisk, class 4
I have tried 1 16gb SD Card, Sandisk, class 4
I have tried a Vivitar Micro SD Card Reader
I have tried the micro SD card Adapters in a laptop, and then in a sandisk USB adapter.
I even tried doing it all using the Nook color via a USB cable.
I even tried leaving the nook color off and connecting the USB cable to the PC to initiate a boot.
Using Windskimager
Using SD formatter
Have formatted Full erase and overwrite.
Tried leaving partition size alone
Tried partition resizing up to 250mb
Tried cm7 zip alone and with gapps
WinXP on 2 desktops and a laptop
It sounds like you have run the gamut of attempted resolutions.
That message is part of the verygreen partitioning script that runs every time the verygreen recovery is run. So, that means the normal boot kernel for CM7 is not loading.
The way the verygreen SD should operate is it starts with uImage and uRamdisk on the boot partition. Those are verygreen's recovery files. The first time it is booted, it looks at your emmc to be sure it is a nook. Then it looks at the SD to see if it has been partitioned yet. If it is not, it partitions it into those partitions necessary for installing ROMs. After partitioning, it looks for a zip to install. If it does not find one, it shuts down and the next time it boots it does the same thing until it finds the first ROM zip to install. If it finds one, it installs it. The first time it installs a ROM, it renames those uImage and uRamdisk verygreen files to uRecImg and uRecRam and they become the verygreen recovery files. And it installs new uImage and uRamdisk files from the zip to become your CM kernel and ramdisk. These are what normally will load in the future to start CM.
Now, with the disk partitioned and CM installed, ordinarily, after the cyanomod logo comes up, it boots by default to CM via the uImage and uRamdisk files. If you intercede with the boot menu and tell it to boot to SD recovery, it looks for uRecImg and uRecRam to load the verygreen recovery. If that is loaded, the verygreen script does all its checking again, it verifies that emmc is a nook, then tries to verify if the SD is partitioned. If it is, it looks for a new zip to install. If, in checking to see if it is partitioned, it cannot find partition 1, it gives that message that has been bugging you.
So I see two things that are happening to you.
First, it is booting to the verygreen recovery first instead of CM. That could be due to a recovery bootloop happening. Look at my tips thread linked in my signature to see an explanation as to what that is and how to possibly get out of it.
Second, after it boots to the verygreen recovery, it does its checking and cannot find partition 1 of the SD and gives you that message.
What I cannot understand is, if you have no partition 1 on your SD, how is it booting to the verygreen recovery?
What you have not told us is what you have on emmc. Stock? Does it boot properly without the SD installed? Or does it go to stock recovery?
After this happens to you again, take the card out and put it in the PC. Tell us what you see. What files are there? Maybe look at it with Mini-Tool Partition Manager and see what partitions it reports.

Ditto on that - especially as it boots happily to that error message time after time after the green cyanomod screen appears and I can also do the menu trick to get it to go into recovery.
Just as a clarifier: A number of times it tried to do the install (text flowing by) and at the end claims it can't find the boot partition - odd (unless I have less of an idea of what I am doing than I think) as isn't all that running from that partition? A fairly even number of times it doesn't even run the install and just errors out right up front.
Once in a great while it all works, and I'm good for a few days - but eventually upon rebooting to get it back to normal (either by menu choice or by pulling the sd card) - all I get is that lack of partition again.

Yes with the SD card out it boots to stock, although a few time what looked like the CWMod menu came up after I shut down and started up without the SD card installed. Maybe only 2 or 3 times out of WAY to many boots to stock so the kids could read their books while I went to work.
I have even tried resetting the nook to factory on the off chance I did something dumb while mucking about to cause that.

Will do so later tonight and will read the notes in your signature as well.
I saw something go by about the boot partition having to start at the 63 block or something - I can't believe ALL my SDcard adapters / writers are bad, but could the nook reader be screwy? Anyway to do a real test? I've been using the Easeus Partition Manager, but will try the Mini-Tool Partition Manager.
Thanks for the step by step explanation of exactly what happens in the process so I can again get a handle on what it's all doing. That all makes sense to what it looks like it tries to do. Deeply appreciate the time!.
You know, I am beginning to suspect something is wrong with your card reader built into the nook. Some sort of intermittent thing like a pin not making a good connection to the card. Put an ordinary SD in it and see if your stock can consistently read it.
Is your unit still under warranty? You might want to explore seeing if you can get it replaced.
Your downloaded verygreen image might be corrupted. Have you tried re-downloading it?

I had thought of that too - at stock it seems to have no problems reading consistently; I've done surface tests using partition manager - but haven't located any real other options of hard testing like once done for hard drives.
Plus the fact that sometimes, it will work for days before it craps out.

A number of times - I went through and wiped all my downloads for the latest try.
Okay So As I mentioned I went back and wiped everything I had downloaded and restarted (again).
Current status is it's working BUT:
suspiciously too easy this time, worked first shot
- (having said that, I've had looking stupid and asking suddenly means it all starts working - so if it's that I'm good with this)
I've only rebooted into CM7, not back to stock at any time
Have not removed the SD card
I've not had time to load up the apps I like, just the kids games
- (sometimes I think it's the more wanted, the less reliable)
Obviously because I haven't removed the SD card, i haven't been able to retry things enough to recreate the other problems of boots right, yet can't find the partition when it really counts.
Changes (listing stupid things too, just because):
-Went back to my sandisk class 4 16gb HC card
-changed USB adapter back to sandisk one, using a sandisk micro to SD adapter that specifically says sdhc (although I think that is really just marketing
-Formatted the SD in the Nook x2, and did not use SDformatter
-Looked at the partition on the card with MiniTool not Easeus partition manager
-There is a step in verygreen's where you pop the card out and reconnect to the PC BEFORE adding the cm zip, made sure to do that - but could swear I had done it before.
Full painful boring steps that SO far has gotten it past the first stage of creation (again the full test is when I boot into stock a few times, or remove the SDcard for anything, or load my really wanted apps on the android side):
--Also note my lack of class 4 Sandisk cards, I only had one after all. BUT I have had this all work to this point with the 16gb only to have it go south.--
Painful details is so I can catch what is really worthwhile different as even WHEN I get it to work, I'm going back to try all the other cards because it worked so oddly and failed so oddly and differently - but that's just me.

I'm going to go the weekend before rebooting to stock as I can do some adding, and rebooting to android.
Maybe backup the droid side this time around.
THEN the death tests on Monday
-thanks for listening_
p.s. - Yes, I still suspect the card reader somewhat as REMOVING may be where it breaks down.
However, once or twice when I had the Unexpected lack of boot partition error - I was able to bring it back by doing a CM7 update via recovery, despite it refusing to find the boot partiton immediately previously - of course that means the SDcard was removed and reinserted. Most time reinsertion = no help.
You do not need to remove the SD to test booting to emmc. Just press and hold the n button during the boot until the boot menu comes up. Then select emmc/normal and boot. It will boot to stock. The only problem with doing that is now your SD boot partition is 'sdcard'. But should work for testing stock.

Yes, I know - but it's two separate tests to see which one caused the problem.
Turns out that neither was needed - it was easier to create; my son simply turned it off (not a reboot cycle as I had been doing which worked).
When it was turned on, it no longer boots - it goes straight to BSOD (actually deep purple).
Booting into recovery gets me:
Penguin Logo
rcS!
Populating /dev using udev: done
Initializing random number generator.... done.
modprobe: chdir(2.6.32.9): No such file or directory
Starting Network...
Detected Standard B&N nook layout, emmc first
Error! Unexpected lack of boot partition on the SDCARD!
Please Report!
Poweroff when ready
Since I'm till held to the noob reposting limit of once every 5 minutes and the captha I can barely read - I'll post MiniTool result in about 5 minutes. I'll link a screen capture if i can here.
I tried to boot per menu to the EMMC stock; Clockworkmod Recovery v3.2.0.1 came up. I know I did emmc and what ever the second default is (which should be normal) - I'm pretty sure it was normal.
I offed it and did the same and confirmed it was the default; THIS time it came up Nook stock.
Is there some way I installed something to the stock NOOK and didn't remove it when I restored to factory? The other day I did the restore from that same clockworkmod screen NOT from the stock Nook environment.
I'm wondering if I somehow created my own monster way back when I first started this and was playing in the android environment.
I just edited what I wrote a few seconds ago. The reason it went to emmc recovery is because the recovery flag was not reset when that SD Recovery told you that error. Did you read my tips about recovery bootloops? When you exited 3.2.0.1, it cleared the flag and booted normally.
I still suspect hardware issues.
Just for Ha, Ha's I hooked the Nook via USB to the PC.
G Drive "Removable Disk G" (wants a disk to be inserted)
E Drive "MyNookColor" ( Lots of what I assume to be standard Nook folders.

Sorry, apparently not closely enough - got lots of time again.
....didn't expect that anyone would be watching, was busy posting pictures so I could go away and read and think...
Probably is hardware - wish I had some way to vigorously test that, I get that basic use in Nook Stock doesn't really prove everything is good.
Plus I bought refurbished and I have to go dig up the warranty, it was months ago, so not too hopeful and boxes long gone. Don't know how nice B&N is, free replacement charger and cord is one thing - whole another refurb unit is different if I can't show stock SD card reading is an issue, not sure how much they check, but I don't think they care about CM7 off a SDcard not working!
Everything looks perfect on that card. All the right files, partition sizes, etc. You have stock on emmc, CWM 3.2.0.1 on emmc recovery.
I still suspect hardware issues. Powering off makes card semi-unreadable. Can still boot to it but when checking for partition information on SD fails.
If you registered your nook, the serial number is all you need. Refurbished usually have a one year warranty. Mine did. Just tell them card reading is intermittent. Which it is. They are pretty generous. You still have stock on there.
Edit: Try just an ordinary SD and power off, reboot, and repeat many times and in between check card reading ability.

Yup, it's really the only thing that hasn't been able to be changed through all of this.
I've mostly gotten these results - I've managed to make it worse as I redid things and apparently got sloppy. But when going back to methodically following instructions I have what I had months ago. I had hoped buying other cards would make it at least act differently.
Thanks for all of the reviews and double checking, at least I now it's not something obvious (but wasn't obvious to me) that I missed along the way!
I'll have to call B&N and see how strict they are and if they take the "It just has trouble reading any SD card consecutively".
Now where was that review of the Nexxus 7.... and I wonder how all the tablet prices are going to drop especially for the Galaxy Tab. Buying is not as fun but I am completely beat with modding failures.
We are too fast with each other. Lol. See my edit above.
