I am trying to get CM7 to boot on my NC with an sd card, using these instructions:
http://forum.xda-developers.com/showthread.php?t=1000957
I get as far as this part
"shutdown your nook and take the SD card out, insert it into your computer.
Copy the gapps-... file to the SD card on the first partition (titled boot) without changing the file name".
When I take the card out of my NC and put it back in my laptop to install market and gapps, it says it needs to be formatted before I can use it. The files that were on it before (the installer image and the nightly build) seem to have been deleted from the card by my nook. Any suggestions?
Remove then reinsert a few more times, if still persists, try to use a usb-sd adapter.
Just to confirm, when you inserted the card with the nightly build into the NC and powered on, you did see messages saying it was installing CM7, correct?
Were you then able to boot into CM7 and set up Wi-Fi before removing the card to copy over gapps?
If the above are not the case, it's very likely your laptop never properly wrote the image to the card in the first place. Even if you did everything right, many people report difficulty with the all-in-1 card readers on their laptops, and need a separate USB reader.
Some things you may not have done right:
Did you unzip the compressed .gz archive of the disk image?
Did you write the resulting .img file to the SD card using a program such as WinImage?
I'm assuming you're using a Windows machine. If not, let us know what OS you're using and what steps you took to write the image, and what results you got when inserting the card in the NC.
Thank you for your replies, but I figured it out. My laptop wasn't recognizing my sd card after I took it out of my nook, but when I put the card in my droid, it saw that the files were there. I added the apps file using my phone and when I went to install them on the nook it worked. Took me five hours to figure this all out but I finally got it. Thanks again.

Hi there. I'm new here and have been trying to absorb as much info as I can and learn. I've been trying to follow the verygreen guide to create a bootable SD card. However there's a step there that's not working as written.
The guide says to eject the SD card once the generic*.img has been imaged to the SD card and then re-insert it into the computer. The following step is to copy the ROM that I want to use (either the 7.1 beta or nightly). The problem I'm having is that when I go to re-insert the SD card, nothing pops up in My Computer.
Did I do something wrong?
Thanks very much in advance,
fuul4nook
P.S. This is a Kingston 4GB class 4 card that was connected to the PC with a USB adapter.
You may have... I managed to kill one making images and using them in my nook. If you know what drive its going into when you insert it try to format it and start over. If it doesn't format, you're screwed. If it does, just do the whole card image thing over again.
What you can try is pop-it into either your Nook or another Android device and try to format it through there.
I've had many instances where Windows would just not recongnize and SD card and the above at least put it back to its initial state.
Thanks for the responses. I was able to mount the SD card on another computer and on a Linux desktop, but my own refused to bring up the drive letter. I ultimately did as you guys suggested and reformatted the card on a different machine and started over.
Appreciate the help!
Hi, I have a nook color and an 8gb SD card. I've followed the posts to get winimage to write the generic-sdcard-v1.3.img written to my card and installed on my nook. However, when I shutdown the nook and put the SD back in my PC, there is no \Boot partition, and windows(xp) says the card is not formatted. What on earth am I doing wrong??
Thanks.

Put it back in the Nook after you have booted into CM7 and format it with the Nook. If you have a camera that takes micro SDHC cards you can probably format it with that as well but will probably want to delete any folders the camera creates later.
Well of course! How stupid am I?? Jeesh! THanks.
OK maybe I'm just missing something big.
After I install the SD card in the Nook with the CM7 upadate on it, the SDCard is modified such that when I remove it, the PC no longer recognizes the format. I get the card in my list of drives, but when selected it says "not formatted" If I choose format, it wipes the card and I can't boot to CM7 from it any more. I can't find a format option on the Bare CM7 image - just erase SD card -which still leaves it in a format that the PC can'd read to put the gapps on.
help??
Logical thinking, dr. wambo.
you have drive C which you install Windows OS on it, and then you format it, what do you expect?
In your case, "boot" MUST be there in order to work, if you format the card, it's gone for good. Question is why you format it after creating it?

Understood. My issue is that after I put the SD card into the Nook and boot the nook, it apparently reformats the SD card such that when I put it back in the PC, I can SEE that the card exists, but no files on it. If I check properties, it shows no free space on the disk (and none used for that matter.) So, I am unable to copy the gapps-gb-20110613-signed.zip file to the SD and restart the nook.
See?
A simple question, do you see the "boot" when your plug the card into your PC (running Windows)?

I do not. Windows explorer shows an SD card in the list, but when selected, it says the card is not formatted.
Card seems to boot fine in the Nook. I must be doing something really dumb. I was able to install honyecomb successfully using this card, but wanted the functionality of CM7. Darn, this just shouldn't be that hard.
Wait, if the card still "seems to boot fine in the Nook" then it means the "boot" is still there, it just Windows not seeing it.
On PC side, try to insertion and removal a few times and see what happens.
If completely nothing, switch to other Windows PC OR if you have the USB-SD adapter, use it.

I should mention that the nook boots fine off the card provided I don't Format it in the Windows box.
Have removed and reinserted the card multiple times into the Win (xp) box. No Joy. Tried a different machine and got exactly the same results.
This just can't be that hard!!
Are you using Windows PC or Linux?
Worst case, reinstall
Windows PC running. XP sp2. ADDITIONAL NOTE. After I winimage the SD card with the generic image, I do indeed have a \root partition. Once I insert it in the Nook and let it boot, shutdown, and I reboot, CM7 is installed and running from the card, but when I put it in the PC, the \root partition is no longer there.
Additional info. I've now tried this on 2 different SD cards and they both do the same thing.
Not sure if you're still having problems, but it's normal for Windows not to be able read the entire SD card after it's been imaged for CM7. There are I believe 4 partitions and it will generally only see the 1st (/boot). Additionally, it will sometimes only read correctly when using a USB card reader, rather than putting the uSD card into a built-in card reader in your PC (not sure why). Hope this helps.
Interesting...perhaps that's the problem. I'm using the internal SD reader on my laptop. I'll run out and get a USB reader and see if that helps.
THanks.

I dont remove the SD card throughout the whole process of formating, imaging, and copying files over to it while it is in the Nook for installing CM7/CM9. I boot to internal Nook software and format the card through the Nook. Then I image it with the appropriate image. I resize it if necessary and copy the installation files over to it and then restart it. I do this because I have had problems unmounting it in the PC and then remounting it again to put files on it from the PC. If you need to add files to the boot parition later on, I just reboot to internal Nook and mount the SD card on PC through Nook software. Works great for me since I hated taking the card out all the time.
Yesterday I installed CM9 to a bootable sd card and my 2 biggest problems with this setup are: can't seem to get a usb hookup to a Windows PC working for either boot or sdcard, and can't get Adobe Flash to work. Anyone else?

Flash does not work yet on CM9. Dunno about the USB..I don't use it.
I am using a recent ICS nightly and have the same problem. It worked on an earlier install so this may be something with the current nightly. One work around is just to boot into stock nook and then connect.
The other night I got a NC with 3.1 and decided to root it and flash cm7 onto it. This all was going fine until after the rom flashed and I booted up the device I have micro SDCard 2GB in the NC and it isn't able to read the SD card it says I need to put one in. Every time I go to download something off the browser it says I need an SD card to download this so and so file. I used my phone SD card in the NC to see if that will work and same problem persists. I have .apk files on my SD card I would like to run on the NC but can't get them off the SD card. This NC belongs to my brother who I was trying to help out by rooting and putting cm7 on it for him but now there's really nothing he can do with it any and all help is welcome. If someone knows how to fix this please tell me. (When I plug it into the computer it still can't read the files on the NC. Even if I mount SD card or USB storage through recovery) please help

Try plugging in the SD card by itself to your PC to see if it got corrupted, and if it hasn't you can transfer your files, format it and give it another go. I hope that helps.
Yep. Sounds like a card corruption problem. I had one. Reformat was the only solution. Be prepared to sacrifice your apks. And always drop spare copies onto your computer, just in case.
Thank you ahead of time for reading,
I have finally gotten my NC to run CyanogenMod 7.2.0-RC1-encore-KANG without any bugs, but I have one problem. Everything works fine and dandy, but when I reboot or power on my NC, it will go straight to recovery. In recovery, I press the first option to reboot, and it usually reboots into recovery again a few times. After anywhere from 1-7 times, it will boot normally into the rom.
Before this, I tried many different methods of rooting, and all of them left me with a buggy rom that would freeze a lot. This time, I simply wrote 8 GB CWR onto my 8 GB class 4 sd card using windiskimager and then installed the zip file for the rom in CWR. I feel like I skipped some steps, but the rom itself works flawlessly, the only problem I have is the minor one where I have to boot several times to get to the rom. How can I make it so that my NC boots directly into the rom, rather than recovery?
Thank you so much for your help and if you need any more details, let me know.
Since the NC looks at the SD card first, it will always boot from any boot files on it. If you don't want to mess with the SD card, simply remove it during boot (assuming that your CM is on the nook itself (aka EMMC)), and it will boot into CM 7. Then push the card in after the loading screen starts, and it will find the card without problems.
So, I guess we would need to know where you installed the rom, and what steps did you skip in the install process.
I am not really sure where I installed the rom. These are the steps that I took:
1. Wrote 8 gb CWR onto my blank 8 gb sd card.
2. Put the card into my nook, booting it into recovery.
3. Connected the nook to my computer and put the CM7 zip file on the sd card.
4. Unmounted the nook and then "installed zip from sd card"
5. Installed the rom and the rom started up after the reboot.
Now I have the problem described above. I don't really want to reinstall the rom in any way because everything works great, but it is a minor inconvenience whenever I need to reboot.
Thanks for your help.
You need to remove the SD card. You wrote CWR to it and it will always boot to recovery if that card is inserted. Once in recovery it is actually take a shortcut boot to boot the ROM which is why it seems like it works. As soon as you try and reboot or boot from power off though it is going to the SD card first.
Just remove the SD card and you should be fine.
Thanks for your reply,
Your method works, but is there any way I can leave the sd card in during boot? This is just for convenience because I have a lot of files on the sd card and my NC is in a case so I don't like removing the sd card. If not, then it is all good.
Thank you!
You should just be able to delete the boot files from the card and be fine.

I think alternatively, you can use one of the bootloaders to set it to boot from the nook rather than the SD card (or from alternate images or recovery images for that matter).

You don't actually have to remove the card. You can just pop it out for a sec (still seated but not engaged) and then push it back in. You don't have to physically remove it. You might also want to check to see if the things are being installed to your portable SD card versus the internal memory. Sometimes it says SD, but the files are on the internal card not your external.
(Oh, and be sure to leave thanks with the thanks meter if it helped).

Once you have used the bootable SD card you don't need it anymore (except possibly for recovery) and you can always create it again in the future.
Ideally you will add recovery to internal memory through ROM Manager or flashing it from a zip before formatting your bootable SD card back to normal. Then copy any data files you have off of the card and onto the pc. Format the bootable SD card back to normal to recover all of the space. After formatting add your files back onto the card and then put it back in your Nook and use as a normal SD card. No more worries about rebooting into recovery.
