[Q] New Nook user, EMMC/SD card dilemma - Nook Color Q&A, Help & Troubleshooting

Hi guys, since a couple days im the proud and happy owner of a Nook color. Before this I had an Archos 70IT, but the nook kicks its ass any day of the week.
But... i am having a bit of a hard time getting familliar with all the terms and policies that come in play when "hacking" the nook.
Mine is rooted using the "burn SD card method". I downloaded a copy of CWM and burned it to my SD, along with the uIMage and uRamdisk files and the latest version of Phiremod. Booted up in recovery, flashed Phiremod and set everything up.
Now, on the forum i see a lot of talk about EMMC and SD cards and running the ROMs from them.
What exactly do these two things mean? Where do I run my ROM from? Which is the preferred/fastest/most stable method?
What is the overall preferred method of flashing/running ROMs?
For example, i cannot seem to boot into recovery anymore because i formatted the "boot SD card" after flashing the ROM. On my phone I am used to just hold vol down and power on to boot into recovery.

This blog may help you sort things out:

EMMC = internal memory ( Electronic Multi Media Card ) it's basically a SD card that's installed inside your device from the mfr. It's the 8GB of memory your Nook color has
SD - is your microSD card
You can run your ROM from either place. Depending on where you have it installed - but the NC - boot priority starts with the SD card - so if you've got a boot ROM installed on your SD - you'll boot from there. Otherwise it'll boot to your NC EMMC - and the SD card will be data.
For example, i cannot seem to boot into recovery anymore because i formatted the "boot SD card" after flashing the ROM. On my phone I am used to just hold vol down and power on to boot into recovery.

Right - you booted off your SD card - and then erased it - so now there's no longer a boot file on your SD card - and now run off EMMC for boot ROM.
You can choose which memory to boot from - if you have a quality brand - fast SD card - the speed difference is minimal from what I've read. So far, I've kept the Nook software in tact for Warranty reasons - and it's easy to reformat a SD card if I want to get the memory back after a ROM install makes the drive " TINY " for storage purposes.
Check out the development section if you want to read more about SD card options - or EMMC ROM installs.

It's actually "embedded" multimedia card...but yeah...

I found out my Nook cannot be registered because I live in holland. You need a United Stated IP address to be able to register. Something with license to buy ebooks online.
So the Nook stock software is kinda useless in Dual boot for me.
I burned a CWM recovery SD card, flased the latest Phiremod and formated the SD so I am assuming im running off of the EMMC...

If your machine can boot into Phiremod - with no SD card in your nook - when you power it up - then you're running off the EMMC.

[Q] Noob question: How to boot from SD?

I tried to create a CM7 bootable SD card per the thread entitled "Size-agnostic SD Card image and CM7 installer for SD Cards. with updater."
I used WinImage to create the supposedly bootable SD card with the installer, placed it into my Nook which was fully off, and the Nook booted as usual instead of from the SD card.
Am I missing something? How do you boot from an SD card?
Is there such a thing as a boot choice menu like on my PC or is the default always to boot from the SD card?
Does the Nook have to be rooted for this to work?
Thanks
ETA: My PC shows the uSD card as nearly full, but my Nook shows the SD card as nearly empty (1.74 out of 1.84 GB available).
When you bought your Nook, did it have a blue sticker on the box? And does internal storage show 1GB or 5GB for you?
Also, you did drop an update CM7 zip file onto the imaged uSD before you tried booting off it right?

No blue sticker was on the box. The internal storage shows 5GB.
Yes, I had a CM7 zip file on the imaged card. (The latest encore nightly)
Interestingly, my PC shows the uSD (2 GB) as nearly full. The Nook shows it as nearly empty (1.74 out of 1.84 available).

When you burned the installer img, did you run WinImage as administrator? Also, when you put it in your reader it comes up as boot (drive letter in Windows, with files like uImage, uRamdisk, mlo, u-boot.bin, right?

Could it be because my Nook operates in "factory mode," in order to skip initial registration?
You should run it and register it and setup wifi and everything first. Get the stock software working fine and dandy (its not half bad actually). Then, checkout this guide for installing CM7 onto an SD card:

I'm not sure, because I ran through initial registration on stock prior to running CM7 off SD --- I used the same image (verygreen's agnostic at http://forum.xda-developers.com/showthread.php?t=1000957) as you did without a hitch.
If you decide to run CM7 off internal sometime you're going to need to register the nook anyway.
You could try an alternate bootable SD (e.g., using an image from here: http://forum.xda-developers.com/showpost.php?p=13283643&postcount=34) to eliminate one of the two: a) your nook having issues booting from SD or b) your SD install is not set up correctly.
An update: I decided to try to create a bootable SD from another bootable image (MonsterRootPack with CWR). This time the nook wouldn't even turn on. I'm going to try to create a third bootable SD as angomy has suggested to see what happens.
I need to add that when I removed the uSD card, it booted normally.
Also, when I create the bootable SD with winimage, I get a dialog box that tells me that the format of the SD card is not right and asks me if I want to resize the image. But this happened on both the images. I don't know if this has anything to do with it.

Ok, I tried the CWR image in the link you gave. Same problem - no-go. Just sits there dead. I remove the uSD and it boots normally.
FWIW you do not have to boot into stock B&N at all before you setup and install to CM7 SD card. One of my NCs has never ever booted into stock ROM at all, I installed CM7 onto SD card and running off that from the moment it was unboxed.
The NC will always boot off the SD card first, so if it's booting off eMMC instead then there must be something wrong with the img that you wrote to your SD card.
Make sure that you have a freshly formatted SD card, preferably one with good small random block r/w speeds (eg Sandisk class 4 8G). Follow the instructions in verygreen's "Size Agnostic..." OP to the letter. Re-download all the files as you may have a corrupted one. Make sure to check MD5 this time. Try using Win32diskimager instead, the 0.1 version works better.
It should work. Good luck.

Thanks for the link. I have given this some thought, and it doesn't seem reasonable that booting from an SD card should depend upon the state of registration of the device because the whole idea of booting from an SD card means that the content of the SD card is loaded in the place of the stock software.

Thanks. Yes, I just replied to another poster that I didn't think that the state of registration of the device should matter since the whole purpose of a bootable SD card is to load the contents of the SD in place of the stock.
I have followed the instructions in verygreen's thread to the letter - several times. Also, I have tried to make other bootable SDs without success. But that's a good idea about trying Win32diskimager. Also, I will try a Sandisk class 4 card SD as soon as I can get to a store.
I do have a question. When I format the SD card what "allocation unit size" should I be using? (formatting through Windows) The default is 32 kb.
PROBLEM SOLVED!
Thanks to everyone for trying to help me figure this out. The winning idea belongs to robot8.
When I switched from using WinImage to using Win32diskimager, it worked immediately. I am now running CM7 on my Nook Color! Took forever and a day to boot though.
Congrats!
Re: allocation unit size, do you mean cluster size? Depends on how big the FAT32 partition is --- larger clusters used means more actual space used but too large a size can reduce access speed. Generally Windows defaults to suggested 4k for up to 8GB, 8GB-16GB = 8k, 16-32GB = 16k, and 32+ = 32kb.
Also the first boot is the longest --- shouldn't take as long after that. Welcome to CM7 - I don't regret installing it over stock after waffling for weeks on whether or not I'd use stock at some point -- CM7 is just too much faster with too many more options and tweaks for my impatience to deal with stock Froyo.
THANK YOU OP!
I had the same issue, tried 20x various ways, 2 different computers, 2 different SD readers, and it was WinImage that wasnt working correctly. Win32DiskImager solved it.
Thanks.

[Q] Nook not booting using SD card CM7, goes into Nook mode

Hi,
Having a with a Nook where it will not complete boot of CM7 which is installed on an SD card. Instead it boots into the Nook Color software.
I hold down the power button till I see the green Cyanogenmod logo with the Loading text, which I think means it is booting from the SD card (I can get it to boot into CM recover), then the screen goes blank and something goes wrong and the boot process continous with the 'n' screen and eventually loads the Nook boot animation and ends with the Nook software loaded. The nook software seems to be running fine except I can't get the SD card to boot all the way.
I've tried 2 known good SD cards, which boot without problems on my second nook, so I know it is not the SD card. I suspect something got corrupted with the boot process files, so I have been trying to find a way to overwrite the existing files with a virgin copy.
1) Can't get ADB running, I suspect the ADB route is only possible if I have the nook booting in a rooted CM7 in the first place (if some one could confirm that would help)
2) I have tried the x8 boot fail reset as well as the erase and deregister option in the nook software with no change in the above behaviour.
3) My last hope is to do an update back to stock using the recovery mode of the SD card. I can copy an updater file to the small partition of the SD card that is visible on Windows. I found a 1.2 stock updater, but it is ~200MB which is too big to fit on the SD card. If someone could point me to a smaller updater or a sd image with CWM and >200MB space that would be very helpful. TY!
What exactly are you trying to do? If you are just trying to set up dual-boot of CM off of your SD card, you don't need to do anything to the stock B&N internal install. I've had good luck using the procedure in the [ROM][CM7] [v1.3] Size-agnostic SD Card image and CM7 installer for SD Cards thread.
Are you sure the initial CM install on your SD card went well? It's known to be very particular (see top of that thread) about what SD cards work. The first few times I tried, I didn't realize there were error when CM was initially extracted which led to similar failures. From what you've described, the SD setup is failing. Normally, you don't need to worry too much about what's on the internal emmc setup of the Nook Color.

Hi bobsto, some background. I've been using CM7 on a microSD for several weeks now. I dual boot between Nook SW and CM7 that way. I've been using the link you posted above to create the SD cards and so far I have not had to touch the eMMC files at all.
Then a friend messed around with the Nook I gave them with CM7 on an SD card. I don't what the friend did, but when I got the Nook back it would not boot into CM7. I pulled my SD card from my working Nook and it wouldn't work either. So I'm guessing someone screwed with the Nook internal files. So I am trying the factory restore of the Nook SW to see if that will fix the problem and allow me to load CM7 from the SD card again. Interestingly Nookie will boot from SD and CM7 won't. Still trying stuff to see what will fix the problem. Suggestions are welcome.

Gosh, I wish someone could figure this out.
I restored original stock after a full CM7 root and it went fine but I can NOT get a dual boot sd card to work.
It seems to install but when I reboot it shows CM7 screen briefly then always boots to Nook OS.
Tried many many different cards and image writers and CM7's and even a card from my other Nook which I know works.
It will not boot into the CM7 from the SDcard.
Any help?

[Q] Please help!!! Noobie messed up NC (big time)

I have a Nook Color. Somehow (and I really can't recall how), I can no longer get to the B&N side of my Nook. Even with the micro-SD out, I still go directly into CYANOGEN. To make matters worse, every single app I try to get from the market will not download. Once I 'Accept & download', the app starts to download then I get an Error overlay screen: "name-of-software" could not be downloaded due to an error.
So I have a V--E--R--Y generic tablet that can't do much. Please help.
Thanx in advance...................................
How did you go about installing CM7? Did you install it to the internal storage?
Please help!!! Noobie messed up NC (big time)
That's part of the problem. I did not consciously install to internal memory, I wanted it to boot from the SD card.
That's what I did...
That's what I did once. I unwittingly installed it onto the internal memory. It also happened to be really buggy. I restored it to stock using Clockworkmod Recovery. Did you use the installer for the SD card?
On a 16GB microSD, I used Win32DiskImager to write 1gb_clockwork-3.2.0.1-eyeballer to a newly-formatted SD card.
I put the ZIP file for: gapps-gb-20110828-signedgapps-gb-20110828-signed, and gapps-gb-20110828-newtalk-signed.
I tried the home-power key combo. It asks me if I'm sure that I want to restore to the factory. I say "Yes" but when the Nook starts up, I'm still in cyanogen mod.
Should I (re-)format the MicroSD, write 1gb_clockwork-3.2.0.1-eyeballer (or another version) then move recovery-clockwork-3.2.0.1-encore?
Aside from not being able to get back to B&N-supplied software, I can't do anything with the NC as an Android tablet.
OP, do you intend to install CM7 into the internal memory?
All I'm trying to accomplish is to get back to the factory NC settings. Once I can get there, I'll decide.
How to hard reset and Factory Default Nook Color - http://goo.gl/pSFui
Power down your NC. Wait approximately 10 seconds or so-- just give it a bit of a break between shut down and factory reset.
Press and hold power button and your "N" home button almost simultaneously-- press Power first and then the N.
Hold these until your screen flashes the "Touch the future of reading" message; hold for a second or two afterward, then release. You will then get a prompt asking if you want to reset your nook to factory. Press the home button to continue. It will ask you to confirm. Press the home key again. Your nook will deregister, reset, and when it reboots, you will see "Kate" in her tutorial video, as if you'd never registered it in the first place.
(Obviously your account info will still be valid-- simply register with your email/pw combo instead of creating a new account.)
Hope this helps- if so please click thanks
Sent from my MB860 using XDA App
I did this (more than once - grrrrrrrrrrrrr!). I never see the "touch the future....." message. Instead, I get a cyanogen mod 7 screen with the message "Booting into Recovery". Then I get a sickly yellow-greenish screen that asks (twice) if I want to teset. I confirm both times then it "wipes" the data. It then boots into a cyanogen mod 7 screen (and the skateboarding 'droid) and I go through the registration process.
Now, when I select a Google app, the downloading (Google Maps) seems to be taking forever, but at least I'm not getting the error I got before.
Also, I do not see the progress of the download that I'm used to seeing on my phone. All I see is "movement" under the "Downloading..." message. How long do I leave it before I abort the download?
Your micro sd card is removed right?

Eyeballer is a clockwork recovery bootable SD image which is used to install stuff (e.g. CM7) to internal memory.
http://forum.xda-developers.com/showthread.php?t=1030227
VeryGreen (size agnostic thread) is the SD image which creates a full OS on the SD card itself leaving the internal memory alone.
http://forum.xda-developers.com/showthread.php?t=1000957
You have used the Eyeballer method and have therefore done an internal install. You must also have installed a CM7 zip not just the gapps zip as they are just google apps and not an actual ROM.
You have 2 ways forward.
The simplest is if you want to end up with internal CM7 and are not interested in running the B & N ROM. Start again by creating the Eyeballer SD card using win32diskImager. Make sure you use a real USB SD adapter and not a card slot on a laptop. Put onto the card the CM7 ROM zip. I recommend the one from the KANG MiRaGe thread in the development forum. It is the most up to date and stable version available at the moment. Also put on one gapps zip (20110828). Now put the card in Nook, Power up and when in recovery then use the menus to format system, data and cache. Do NOT format boot. Then flash the CM7 ROM zip, then the gapps zip. Power down and prepare a clean SD card either by reformatting the eyeballer card with something like the HP USB card utility or a partition manager in the PC like miniTools. You could also use a different SD card if you want to keep the eyeballer one for future use. Put the card back in, power up and you should now be in a stable CM7 environment where you can set up wifi, register with the Google market and download apps.
The second way if you really want to return to stock on the internal and run CM7 of the SD card then use the eyeballer method but instead of flashing CM7 and gapps you now use a return to stock zip. Make sure you still format the partitions as before.
http://forum.xda-developers.com/showthread.php?t=914690
Once you have it back to stock and upgraded to whatever stock you want then follow the VeryGreen method from the link above. Once the SD card has put CM7 on itself, do not worry that there is only a 114MB space if you ever put the card back in the PC. That is normal; it is just the boot partition that the PC sees. The rest of the card can be seen if you USB connect the Nook to the PC.
Yes it is. Also, even though I'm not getting an error, no apps are loading.
You absolutely rock!!!!!!!!!!!!!!
I'm back at the NC "baseline". I tried to go back to a 1.2 (which is what it came with) using "update-nc-stock-1.2-signed". Once I re-booted, it kept returning to the NOOK COLOR screen. Then I used a 1.0.1 from your last post. It came back fine with 2 exceptions. 1) I now have a message that I need to install a SD card. When I do, my (Windows Explorer) "Computer" screen only recognizes the SD card and not the Nook. These are piddly little issues, but if I can get them fixed, great! (Right now, I cannot upgrade the NC or move any books or load any apps.
Thanks again!!!!!!!!!!!!!!!

I had this same problem. Since I am a new member, and can't post links, I'm going to try to help.
Install Clockwork Recovery to an SD card. Yes, the same way you did when installing clockwork to the SD the first time.
There are some threads on other fourms (google is your friend) that have links to Update files that allow you to update while keeping clockwork recovery, and some that will remove clockwork recovery. If you can remove the SD card and boot into the Stock Nook OS, then don't worry about installing 1.0.0 or 1.0.1 like some of the forms say. Just place the .ZIP file of the hacked update (usually 1.3 or 1.4 I think) into the root folder of the SD card, then Install it on your NC just like installing CM7 onto the internal memory. Your nook should start working again. It restored mine to full functionality. I can now pay 3 Dollars for angry birds, but at least its not as terribly slow and laggy as it was with CM7.

I had the same issue last weekend, somehow my internal memory had become unrecognizable to anything, and the local Barnes and Noble store had a SD card that repartitioned the internal memory, and I was back in business. And as an added bonus I now have the 4 GB app/BN partition and the 1 GB mostly useless partition.

The instructions I see when googling around where I see that image mentioned are instructions for installing onto the Nook Color internal memory.
In the simplest case, making an n2a card is much less complicated than that ~ all you need is on the PC, write the size agnostic image, then drop in the CM7 build you want to use, then put the card in the Nook and it creates itself. There are upsides and downsides to different n2a methods, but that one seems to be the easiest ~ I've done it successfully several times, and I'm certainly nothing like an expert when it comes to these Android systems.
A recovery card image will make a bootable recovery card ... and while that might not have been what you needed to get what you want, its what you need to get the nook back to stock.
You might want to go to
http://forum.xda-developers.com/showpost.php?p=22809801&postcount=148
... to get a version of the 1.4.1 upgrade that your recovery card can install. You'll probably have to wipe all sorts of partitions, which means you'll have to sign in with the B&N store again and you'll get to download you B&N apps again, but that's pretty straightforward.
This OP in this thread:
http://forum.xda-developers.com/showpost.php?p=10623716&postcount=1
... says that it will be necessary to format ("wipe") the /data and /system partitions, but it doesn't seem like you'll lose anything you want to keep. After all, you've either overwritten or completely tangled up your stock B&N info.
That post above has 1.4.1. There should be a signed 1.4.2 lying around somewhere, but if not, once its back to stock, you can update to 1.4.2 the normal way, download the B&N update file, drop it in the root of the Nook, make sure its at least 30% charged, and let it go to sleep, which will run the update file.

booting from sd - issues with 32gb card

Trying to prepare 32gb card for nook cm7
Using verigreen's size agnostic img
Wrote it to the card using win image writer
dropped cm7 and gapps
on boot it recognizes card, makes partitions, inflats stuff everything looks ok
on reboot it does NOT boot from sd
instead goes to nook default
exact same stuff on 8gb card works fine
what gives?
I have two nooks at this point
both may have cwm recovery - i dont know how to check
(I know how to use nook, update it etc, but not sure about this cwr thingy)
one has cm7.1 on emmc
other has nook 1.2 rom on emmc
in both of them if i insert 8/16/32gb card
1) if sd card has fresh verygreen image with update...zip and gapps..zip installer kicks in and preps sd card
2) once i reboot, it ---- does NOT ---- boot from sd card anymore
All I want is bootable sd card with cm7.1 on it so that I can give it to a friend of mine
what am I doing wrong
is there a way to force nook to boot from sd card?
I think if it finds cwr on emmc and cwr on sd, it boots from emmc or something
I use win32diskimager which I think gives more reliable results.
Also you must mount the card in a PC for writing the image using a real USB / SD adapter. Using a card media slot on the PC or using another device like a phone to mount the card are known to give problems.

Only put the CM7 zip file on it for the first boot.
use easeus partition software to extend the size of the boot partition to 200 MB after you flash the card with verygreens installer, but before you put cm7 and gapps on there.
I bet you it fails to write the kernel during the install because there is insufficient space - try it again without resizing and pay attention to the readout when it scrolls down the screen, you'll see.
cm7.1 + gapps is almost your whole boot partition, for me it leaves only half a megabyte of free space - that's not enough to unpack and install what's needed.

Sorry for the OP but also happy for you that your NC is up and running.
I keep saying many times, do it one at a time.
...........
Sorry to bring this thread back but I'm having the same problem using verygreen's tutorial on my NC 1.3. However after booting the NC I get the "cyanogen mod loading..." screen shortly followed by a blank screen (Nook doesn't turn off, though). If I remove the SD card the nook starts up as it normally would.
Followed the advice of these other members (extended partition size to 16gb/16gb, haven't installed gapps either) but I still can't get it to work.
I'm using the latest nightly release of CM7 following the link on verygreen's tutorial released on 11/23. Should I use a stable version instead?
Thanks...

There's where you made your mistake. The recommendations of the others on the forum were probably to expand the partition created by verygreen's image to something like 200MB or 250MB. The scripts in the image create and format 3 other partitions in addition to the one created by verygreen's image. When you expanded it to the full size of the SD card there was no room to create the additional partitions.
I would suggest you re-apply verygreen's image, expand it to 250MB and try again.

[Q] Chronic "Unexpected Lack of Boot Partition on the SD card! Please Report"

[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.

-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:

Initializing random number generator.... done.
modprobe: chdir(2.6.32.9): No such file or directory
Starting Network...

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.
