Fairly new, help booting from sd card

Hey guys just got a nook color last night been doing some research but i made a card that I believe should have been able to boot from sd upon start up. I have not been able to get it to do this. I am not sure what needs to be done im running stock 1.2 and not feeling rooting yet just booting cm7 from the SD but if i need to root I can. Please advise i have looked around and searched and not found adequate information? Thanks

If you follow the instructions in the forum you should have no problems. My suggestion is to try verygreens SD size agnostic setup. Follow the instructions exactly and you should have no problems.

k that's the one i followed but do i have the card in the nook when i write the image to it? because it says after writing the image to it to place it in the computer... also do i need to hit anything specific to boot up from SD when i turn the nook on? because those are the instructions that i followed and i have had no luck
edit: also if i am writing the disc onto the SDcard while in the nook how would i go about doing so?

but do i have the card in the nook when i write the image to it? because it says after writing the image to it to place it in the computer...

I was also confused by this...

I'm having the exact same problem, and am having no luck on here trying to read and find the answer.
I just got my Nook Saturday night from Best Buy, and updated it to stock 1.2. It's not rooted. I haven't done anything to it yet. Spent most of the day yesterday just trying to get the loader image to burn to the sd card, kept refusing to do it. I am absolutely NOT a geek, and hubby (who is) finally figured out what I did wrong when he got home last night. Apparently the program I used to unpack it, had it bloated to 4 GB, instead of about 130 mb.
Well, he tried following verygreen's instructions to put CM7 on the card (8 GB class 4) so we could use that in the Nook. Can't get the Nook to boot with the card, it just keeps booting stock. Once booted, I can see the card in it, but it is not booting from it. Also, there is no Touch the future of reading screen on this nook, there is a screen that says Read Forever, if that matters. I'd sure appreciate any insight into why it might not be recognizing that it should be booting from the card.
I was really excited to get this, it's the only decent tablet I can afford, but I'm a bit frustrated. And hubby doesn't really have the mental energy to deal with this sort of thing during the week when he comes home from work. And I really wanted to learn how to do this myself, so I can do what's needed when he isn't here...
Thanks ahead of time if you read all that and can/want to help me!!

It seems likely that the card didn't get made into a bootdisk correctly.
1) Are you using windows, mac, or linux?
2) How was the μsd card connected to your computer when making it into the boot disk?
3) When you connect the card back to the laptop in the same way, what happens? What is the card labeled?
Oh, and it says "Read Forever" in 1.2. "Touch the future of reading" is from 1.1, and also CM7.

Thank you for responding! I have actually fixed it finally. Seems the Microcenter card I was using must not have liked all this. So I had another card laying around, a 4 GB, no idea what brand, and tried it all again. This time it worked! So happy now, got it all going so I can play with it now!

[Q] Help pls: Nook booted from SD w/CM7 good 4 3 days then started to boot to stock

Ok, I've been reading the forum until my eyes are popping out. I can not find my situation. So please forgive but I've been searching.
Bought a NC for my daughter for the purpose of Rooting it using the SD method. I followed the routine install last Monday:
1. Using WinImage, I burned the Size-agnostic SD Card image on the SDcard (Transcend 8GB Class 6 SDHC) using my HTC Incredible as my card reader.
2. Downloaded cm_encore_full-131.zip and moved it to the card.
3. Installed the SD card and bam! Everything was working and I was happy as hell!
4. I went through the process and got gapps-gb-20110307-signed.zip installed and I was working away downloading apps and stuff.
5. Downloaded update-CM7-dalingrin-OC-sd-063011.zip and got that loaded and our NC was flying high. And since we have the right kernel, downloaded Nook Tweaks and we can use a case with a USB keyboard with no issues playing Angrybirds and everything. LOVING IT!
I was happy as hell cause I wanted to be done in my limited time before tomorrow because my daughter is staying with my mom and this will give her something to do.
THEN today after powering it off. I powered it back on again and the following happened:
1. It appears to attempt boot from the SD card.
2. The green Cyannogen logo comes up and under it it says "loading..."
3. However, instead of the Android on the surfboard coming up like before, it will boot up to the stock Android with the N splash screen first then to the stock interface???
I tried several times powering it on and off to see if it was just a glitch but it still did it. Soooo, I redid the whole process again. But once I tried to boot from the SD card with CM7 loaded, the same thing happens. Green logo, loading..., then back to the NC stock OS.
I tried downloading the image a few times to make sure it wasn't corrupt and reburned the img on the SD card, tried booting it again and still the same results. (I did this whole process at least 5 times!)
Sorry for the long read but I am frustrated and disappointed that i will have to tell my girl that it's not working like it was earlier. Can someone give me any advice to try? Or what can I possibly doing wrong? I'm beyond my skill sets at this point. The only thing that I can find on the forum is that it maybe the Transcend SD card but it worked find for three days. Can it really suck that bad after 3 days? I only have tomorrow to work it during the day so If I have to I'll go to Costco and get a Scandisk over there as some have mentioned, I will. But if there is something someone can tell me to try, please let me know.
Thanks in advance!

You are probably on the right track with getting a new SD card. One of two things happened: the SD card failed during the initial "burn-in" period or the Nook's reader slot did. The card is thebmore likely point of failure.
If the problem persists with a new card, get your Nook back to B&N for warranty replacement. Just don't let them have your SD cards an you won't lose all your work
P.S. Yes, ANYthing electronic can "suck that bad after just 3 days". If an electronic component is going to fail, it will either be DOA (and even cursory quality control will catch it) or it will fail shortly after being placed in regular service (burn-in). If it survives the first 60 to 100 hours of use, it will PROBABLY last for years.

Thanks DiDGR8!
I hear you on the electronic part. I was also really tired when I posted. I guess I just didn't want to believe that the card was the issue or rather could be the issue specially when I can read the card from my phone and read it from the NC in the stock interface. It had to be something I did or forgot to do. But I've seen stranger things happen. LOL Things can break.
As soon as I can, I will run out and get a new (Scandisk) card and I hope that it resolves the issue. I hope it is not the NC's reader slot because I hate going through the "returning process" plus we have to leave tonight.
I'll post my results as soon as I can today.

I often not to believe the uSD card itself is the problem but I guess this time, I believe it.
I have the same card as yours (Transcend 8GB class 6), testing random read/write small block and the result were about 0.08 (meaning bad). Sure enough, running CM7 off it last few days then I got ton of FC errors. I now then boot CM7 from eMMC and use the card as an external storage, the card still gives me some problems.
Try Sandisk and keep yours fingers crossed.

Well at least I'm not alone. Thanks votinh!
I wanted to avoid running it from eMMC so that if i wanted to I can do the warranty thing.
Well, I got me a Scandisk 4Gb Class 4 this morning in addition to a card reader/writer to eliminate my phone as a card reader.
Followed the steps and still the same thing. However, I did noticed this time some I/O errors come up during the installation process.
So, I let it go to stock so i can test my phoness SD card (Scandisk 2GB) and it worked just fine. So, I'm really stumped now.
I'm going to try flashing it again a couple of more times. I can go to B&N and tell them it is not working but if i show them it does work reading my phone's SD card. unless i just push them for an exchange.

OK, tried the the latest stable and now the Driod comes up and it is in a loop. I abandoned that all together. Need to stay focused.
So, I went through the process again using #133 on my Scandisk 4GB and tried to boot with it. Same results again Green logo, loading..., then back to the NC stock OS.
However, this time I was able to take a pic of the screen so I can copy what I saw when I saw I/O errors during the installation. So at one point I got:
end_request: I/O error, dev mmcblkl, sector, <insert number>: this flashed down the screen quite a bit
also
JB2: DetectedIO errors while flushing file data on mmcblk1p2-8
Ok so I went back to the Transcend card and did #132 but using my new reader. This time it seem to install clean. When I powered it back up, this time str8 to the "Read Forever" splash screen and back to stock. Weird.
So, I redid the 4GB card again and got the I/O errors again same thing the "Read Forever" splash screen and agian back to stock. It's like it's telling me to go F*** myself.
At this point, I'm thinking its the NC reader reading off the card itself. I tried 2 brand new cards, dif brand, dif reader/writers, multiple downloads of the img and installers...I don't know what to say. I should just root it to eMMC but if i'm having trouble with the SD method and I go eMMC and that messes up I won't be able to return it on Warrenty. What am I doing wrong? Can anyone give me anything else, I'm desperate and ready to fling it out the window. LOL

LOL I love the way I'm bumping my own thread here.
So, I went to B&N and got me a new replacement NC without any hassles.
I ran through the routine from scratch with CM7 #133 (which I believe has the OC kernel in it) on my new Scandisk 4GB Class 4 without the gapps.zip just to take it one step at a time.
I powered it on and prayed to the CM7 gods. I see the same I/O errors on the install and I also saw chown: cannot access '/tmp/backuptool.sh' : No such file or directory which I've seen before as well. However, this time the droid came up refreshing itself in a continuous loop. Like when I tried the stable version earlier. I did this twice and the same results.
At this point I'm thinking it maybe the WinImage. I'm using Winimage V 8.50? So, I downloaded Win32disk imager to give it a try and using my phone as the reader again because that was the last known combo. Again, the same errors. Then the Logo, loading…, this time blank screen…crickets…
I’m out of ideas…I had a clean install once on Monday worked fine until yesterday and I can’t do a damn thing.
Different SD cards, 2 brand new NCs, different readers, multiple downloads of image, installer, etc. Two dif imagers as well…Someone please tell me you are missing a step or doing something working because this does not make any sense… Booting in recovery mode maybe?

The only idea I have is a longshot. When you were getting the looping bootanimation (the blue Andy on a skateboard), or the "crickets"; how long did you wait before aborting the boot?
I have seen it take a LOT longer in those steps than I ever remembered (or thought reasonable). I'm talking 5 or 10 minutes.
It has something to do with recreating internal partitions and the dalvik cache (IIRC). It's been so long since I booted off the SD card, I'm not really sure what is supposed to happen that way.
Sorry that I can't offer more than "just let the first boot take all the time it wants".

It's all good. I understand.
So, Truth be told I think the first time with the "stable" image I let it go for 3 rotations before I said jumped ship. As I type now, I tried going back to #128 and it's doing it again. Andy has done skated across it at least 20 times...21... I'll let it run for a bit since you say that while I research the recovering to stock in emmc in case I decide to chuck it up and go emmc. This is driving me crazy. I would guess that emmc maybe more stable than running it from an SDcard.

You have got to be s***ing me. So I staied persistant and used my 8GB Transcend card again. This time it installed clean (I was taking pictures so I can read the damn thing) and booted clean. WEIRD!!!
I'm going to see if I can get my Scandisk to do the same.

I have seen mention that using the latest winimage is not a good idea, something about it not working right.
Version 8.1 is the usual recommendation.
I have been using the dualboot image racks11479 put together, and i've burned it with winimage a handful of times without issue, but always used winimage 8.1
Not sure if that's your issue, as i've never forayed into the realm of recent nightlies, but it could be a contributing factor.

Win32Disk Imager works perfect for me, even on win7 x64 and winimage would write, but the disk wouldn't boot.

[Q] Help w/CM7 sd card install on new NC

Hello, Just got a refurbished NC with version 1.2 (read forever). Works great from stock system, but I'm trying to install CM7 on SanDisk 8gb card via post directions on:
[ROM][CM7] [v1.3] Size-agnostic SD Card image and CM7 installer for SD Cards
I've tried the 2 latest stable updates 7.1.0 and 7.0.3 and everything seems to install fine with the last lines saying "all steps complete...flushing caches...shutting down"
When I restart, it goes to the last 20 or so lines of the install and shuts down again (same messages at the end...all steps etc) I've redownloaded both the green 1.3 installer image and the stable roms. When I tried a "nightly" the install stopped on a line saying "looking for file starting with update..." or something like that and it sat there until I held the power button for a looong time.
I did try searching for a solution but couldn't find one like this problem. Any ideas what I'm doing wrong or not doing? Thanks
One thought...the 8gb card doesn't show what class... it only says Sandisk Micro HC

Are you certain you are dropping the CM7 files on the root of the boot partition on the SD?

You seem to describe doing it right but we need step-by-step how you get it done in order to maybe figure out where the culprit is.
I would suggest RECREATE the bootable uSD first.
Note: redownload the image file if needed.

Thanks for replying. Here's what I've done:
formatted 8gb micro via windows 7
downloaded image installer 1.3 via xda
downloaded winimage
restored sd card from image (generic...)
I saw boot disk w/4 files
downloaded latest stable cm7 and copied directly (zipped)to boot partition on sd
inserted sd in NC
it loaded and started updating for about 60 secs like mentioned above
it automatically shut down
When I restart NC, there is a quick white screen it goes to loading and redoes the last 20-30 lines of update and shuts down again. The lines go by so quick I can't read it (or more accurately remember them)
I've redownloaded both install image and stable updates with same results. When I tried downloading a niightly, the installer stopped midway with last line saying something like...looking for file starting with update...
Any help is appreciated

I have the same device as you (refurb NC 1.2 from the recent dailysteals sale) and did the exact things that you did except use win32diskimager instead of winimage, and it installed the cm7 nightly 240 without any issues. It's only afterward that I ran into trouble, trying to install gapps (read about it here: http://forum.xda-developers.com/showthread.php?t=1332441)
same device, same procedure, different results.

You might want to re-download cm7 zip file... you can use 7-zip or winrar to "Test archive" to see if it is corrupt before copying it to the boot partition of the uSD.

Like jh mentioned, I would give win32diskimager a try, there were many reported of winimage didn't work well.
Search for the win32diskimager, older version is better for some reason, 0.15 or something. If you can't find, let me know, I'll host the file.
Again, redownload all files, make sure no hiccup in the middle of downloading process.
What you did was correct, just to let you know.

Work-around works---next question
update!
I took out the micro 2gb sandisk from my phone and tried it again doing the normal install. It works! So, next question. Can I make an image of the 2gb sd and restore it on the 8gb sd and via some procedure maximize the rest of the sd?
Any ideas why 8gb didn't work in first place? I had done a full format via windows explorer before trying the first time. Even tried formatting via NC and still no luck. The 8gb was being used in my rooted Eris phone with no problems.

By any chance you got the counterfeit one? the 8GB

not counterfeit...I think...because when fully formatted it was 7.4+ gb

Found another 8gb sandisk micro and used it. Worked perfectly. I should have tried that first and saved a whole lot of time and energy! Thanks to all that chimed in with suggestions.

You have to use at least a class 4 card and that still works pretty pokey. I have my nook overclocked and running on internal and it is almost as fast as a stock Atrix

[Q] Nook Color Rooting Issue.

New here, yes I did look around. Found lots of other good info, but not this. If I missed it, feel free to remove my man card. I just got a nook color for x-mas yay me. I have followed two guides:
Well I tried to post two links but that wont work. I understand. Anyway, one guide is called How to Install CyanogenMod 7 on the Nook Color (PC Version), found it on Youtube. Other is called How to: Root a Nook Color, install CyanogenMod 7, and overclock it off of icrontic.com Hope that helps.
I am using at 8gb version to write to SD card. I copy both files over without un-ziping them. Follow all directions. However nook will not boot into Cyanogen. I just get the normal nook boot up. I have tried several times. I am new to the whole rooting thing and have seen people post different versions of the same file. Not sure if that has anything to do with it.
Lastly,
Nook firmware: 1.3
Not using a Scan Disk SD card.

I assume you want to enjoy the beauty of CM7.
Before guiding you, a very first basic question needs to be asked: do you want/intend to run CM7 on eMMC or off the uSD?

I assume you want to enjoy the beauty of CM7.
Before guiding you, a very first basic question needs to be asked: do you want/intend to run CM7 on eMMC or off the uSD?
Well I didn't know there were other options other than CM7. I have also been told that is one is the best all around one out there. You will have to excuse my ignorance but what is eMMC and uSD?

Don't worry, we all learn something day to day.
CM7 is a custom ROM (or OS if you want to call it), which replaced the stock OS by many of us. It is one of the most used ROM out there for NC (short cut for NOOKcolor)
In order to run/use CM7 on the NC, there are 2 choices:
1. Installing and running it (CM7) from the internal memory (a.k.a. eMMC) or
2. Booting and running it (CM7) from the external uSD card
You can spend the whole day searching for the difference in details, here, I just give you some quick thinking of the 2.
Running from eMMC = more complicate installation process, smooth performance, a lot less FC's (Force Close = applications hung), easy to backup, more storage. But you will void the B&N warranty since you delete their original stock OS.
Booting off uSD is a quick way to explore the beauty of CM7 or any custom ROM WITHOUT effecting the stock OS, meaning still under warranty. Down side is you need to have a 8GB or 16GB Sandisk class 4, which probably costs about $20 (onsale for 16GB).

Ok does it have to be a Scandisk sd card? I thought loading CM7 via SD card removed the warranty also. A side question I have. I saw on youtube someone was able to "dual boot" the nook OS with the CM7 OS. They could swap back and forth, any idea what this is about? Sorry I don't have much more information on it than that.
If loading through SD card does not void warranty I would prefer that for the time being until I get the hang of this stuff more. Then again a fully rooted nook is basically a android tablet+nook. The only reason I would want the warranty is if something inside were to break.
Would the reason why my attempt didn't work be related to the fact that I didn't have a Scandisk SD card?

No, it does not have to be a Sandisk but Sandisk (class 4) is the best (have been tested) on the market. You can use any other brands, it might work and might not. Therefore, if you intend to run CM7 off uSD, Sandisk is strongly RECOMMENDED. If you use the uSD as an additional storage, any brand is OK.

No, it does not. Running off uSD has zero effect on stock OS.

A lot of people mistype or mis-use the term "dual-boot"
AFAIK, there is 2 kinds of "dual-boot" (one of them is incorrectedly used)
a. Leaving stock OS on eMMC and booting CM7 off uSD.
b. Installing 2 different ROMs on eMMC.
I personally choose to say b. should be called "dual-boot", not a. but a lot of people calling a. as "dual-boot". I don't mind.
What your question is for item a.
All you have to do is during powering up, press and hold the "N" button then select booting Normal, it will boot into whatever on the eMMC (i.e. stock OS) even having CM7 uSD plugged in.
If loading through SD card does not void warranty I would prefer that for the time being until I get the hang of this stuff more. Then again a fully rooted nook is basically a android tablet+nook. The only reason I would want the warranty is if something inside were to break.

A very good choice. Go for it.

I don't know what you're doing so can't say.
What have you done?

Ok sorry it took me a little bit to get back to you guys. I work the night shift so it can be a pain and make you seem like a ghost.
So I downloaded a file called 8gb_clockwork-0.7. Used a program called Win32 Diskmanager to write that file to the SD card. I have an 8gb SD card. Not Scandisk.
I then copied over two file that are .zip files. I did not un-zip them. Files are gapps-gb-20110307-signed and update-cm-7.0.3-encore-signed.
I am using my phone as a micro SD card reader. Could that be causing issues?
Everything I read said to do what I just said/did. I then pop in the SD card into the nook. My nook then boots up normally, I.E. standard nook OS.
Any help would be greatly appreciated, thank you.

Again, it goes back to my question in post #2.
Before getting an answer from you, I cannot provide any more help.
In fact, I don't want to guide you through the wrong direction.

I would like to run it off of the USB drive until I get familiar with it. Just in case I do not like it. As this is my first time rooting something I would like to keep my options open.

I assume you meant to run CM7 off uSD (you said USB drive???)
Anyway, if that's the case, what you have done was incorrect.
Forget about it, start over again.
With your not Sandisk uSD card, I wouldn't recommend but if you have to use it, then go with it for now.
1. download "win32diskimager" (I hope you already it)
2. download the "Size-agnostic SD" v1.3 imager from this link: http://forum.xda-developers.com/showthread.php?t=1000957
3. try this ROM (build 12122011) as many others like it from this link: http://forum.xda-developers.com/showthread.php?t=1344873
4. download this GApp (20110828) for CM7 from this link: http://wiki.cyanogenmod.com/index.php?title=Latest_Version
5. try to follow verygreen's instructions from the link that I posted in step 2.
If you not able to or hitting issue, get back here for more help

Will do. Thanks again for all the help. Also yes I did mean uSD :/ I will try this Wednesday during the day and get back to you as I am about to start another shift.

[Q] problems with sd partitions

ok first let me start with I have the tab 2 7.0 3113 with stock jellybean. I am new to the tablet world but not android my phone works much better than this tablet. I have been trying to deal with the inabiltiy to move apps to sd card by the way the worst engineering screw up known to man a simple task that can be done on any android phone but not my $250 tablet. Sorry getting off track been surfing every forum for an actual fix for 3 days. first i tried the simple fix via app2sd or link2sd withno prevail neither worked ad no other program i could find did either not titanium back up pro nor rom toolbox. I have tried partitioning the sd card with clockwork mod and minitool both say its partitioned but still cant move anything. And i keep getting a low internal storage space which keeps me from doing update i used funny patcher to fix that issue but still cant figure out how to actually really trully not just link2sd but actually download apps to my ext sd card and move some of my bigger games there for storage i have a 32gb sd card that barelly has anything on it nothing works i hav done 4 factory wipes and even tried night time build rom which wouldnt function on my tablet. My tab 2 is rooted by the way please if anyone can think of anything else to try let me know my hands are up in the air.
Thankyou in advance.

First, Welcome to XDA. Not let's see if I can explain...
The device has two "sdcards". One internal and one external. By default, apps go to the internal sdcard. You'll need root and one of the many scripts around to trick the device into thinking that the external sdcard is the internal one. I have the same tablet BTW. Love mine.

how do i do that i have already partitioned it with mini tool and mounted it with clockworkmod what am i missing

Search... We stress using the search function here at XDA. The main reason is you'll never learn if someone gives you all the answers all the time.
Although you say you've mounted the sdcard in CWM, it's only mounted in CWM. Once you reboot, it's no longer mounted by CWM as CWM is no longer in control. Linux and Android are in control now.
Being the nice guy I am, I'll point you in the right direction this time. But from now on, please search, and search again if no luck the first time. Check out this thread.
Good luck
