I can't seem to find a step-by-step procedure to get my NC to dual boot w/CM7 on SD card & ManualNootered 4.5.18 (1.2) on eMMC. Can someone please point me in the right direction?
I am currently using CM7 via size-agnostic SD card setup. Can I use this existing image & add the dual boot capability, or do I have to start from scratch with a new image?
Thanks for your understanding. I really did search for this answer.

I'm looking for some help with my nook color. I have read multiple threads and I'm looking for the best solution for my situation. I'm currently running version 1.2 on my unmodified nook. When I boot my nook I would like to have two options, the primary option would to boot an unmodified standard version of the nook OS. The second option would boot CM7. I have a 2GB sd card I can modify in any way, however I do not want to modify the nook OS at all. I'm looking for simple instructions on how to do this without modifying/erasing the current nook OS. Could someone reply with the xda link that would work best with my situation? Thanks!
I was in your shoes last month and it can be very confusing and intimidating to get CM7 up and running. I will try my best to help you out.
First of all, the most important thing is the SD itself. Around 99% people here have had sucess with Sandisk Class 4 SDs in 8 or 16 gig. Other brands, even with higher class ratings do not perform as well due to small block random write speeds being too slow.
Here is the thread regarding this:

After you have a suitable SD card, then the instructions on this thread will take you through the steps to creating a CM7 run from SD system:
[ROM][CM7] [v1.3] Size-agnostic SD Card image and CM7 installer for SD Cards.

There are also videos on youtube that will help you through the process.
I used these videos as a reference to help clear up the parts I wasn't sure of.

The one part that really gave me trouble was getting the NC to boot into recovery mode.
I would recommend the size-agnostic install thread from the dev section...

This will guide you through installing CM7 onto your microSD card. In the latest CM7 versions, if you press the 'n' button while the boot logo is displayed, you will go into the boot menu where you can select to load from emmc or the sd card, including the options to boot normally or go into recovery mode.
Note that I had toyed with one of the dual boot options previously, but I found out later that they don't seem to be recommended since they use a custom uboot. The basic functionality was rolled into the standard CM7, as described above.
I followed this thread to create a CM7 bootable SD:

Is there a way to dual boot to the stock rom without removing the SD card?
Thanks.

remember to read all the instructions before attempting, but it's fairly easy to do.
and also, remember to use the search button.
Very nice, thanks!
Hi. I am awaiting delivery of a new NC which I ordered after reading about "nooting" and running Honeycomb etc. I am a total noob and trying to get my head round all the different procedures has left me a bit confused! Can someone tell me if I'm right in the following : 1) My new NC should be (or will be after connecting to WiFi) system version 1.3. 2) If it is, and I do not want to mess with the internal ROM/booting/processes, it is possible to install HC on a 4Gb SD card along with an "img" file called phiremod 6.2 (available from :http://forum.xda-developers.com/showthread.php?t=1045018) in order to burn an image to the SD card that can just be stuck in and which will allow me to boot the NC into Honeycomb OR Phiremod depending on how the Nook's start button is pressed. 3) If I just want to use the original system, I can then just remove the SD card before powering on. I.e "Nooting" is not necessary if you go for the dual boot system? If I am right in the above, is there an up to date HC/phiremod image file for the Nook 1.3 as of this month (i'e newer than the one mentioned above) and could someone kindly point me to it?? Many thanks to all in advance, and sorry if this has been asked, but the info here is overwhelming!
That's what I did with mine. I'm running the Dual-Boot Phiremod 6.2 and Honeycomb from the SD card. The nice thing is with that image is the boot menu also gives you the option to boot from eMMC so you don't have to remove the SD card to boot into the stock OS.
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?

Thanks, the first worked like a charm!
I made a 32gb CM7 sdcard.
Still wish I could have got the size-agnostic card to work, it bugs me when I can't figure stuff out.

I'm in the same boat, but after 1 day of research and trial and error I'm happy it works. Maybe someone smarter will see this and know the answer and solve my problem curiousity.
Hi there
I am new to the tablet world and recently got a nook color. I decided I would like to make it more like a tablet and have been trying to root it but to no avail. I've tried everything, even the guides posted in the forums right here. Most recently I extracted the clockwork mod 3.2.1 to my 4g microsd plus moved a cyanogenmod zip to it as well. Every time I boot up my nook however, it goes straight into the normal OS welcome screen. My version is 1.4.3 and would like to find a guide that deals specifically with this version. I have been successful in the past getting into the microsd boot menu but the zip files that I install never show up. Thanks in advance for any pointers anyone can give me on this and I hope I am posting in the correct forum.

Looks like you are having two issues.
One is getting the CWM card to boot to CWM instead of stock. There can be several factors that determine whether the card will boot. Look at my Nook Color Tips thread linked in my signature and read item A9, bootable SDs. It talks about the issue. Rereading what you said, you say you "extracted to the SD", you mean you burned the .img file to the SD with burning software? Followed by copying the zips to the card?
The second issue is why your zip files don't show up. I am not sure what is causing that. When it boots to stock, can you see the files with the stock file manager? In the CWM menu when you do get it to boot to CWM, are you choosing the option that says "install zip from SD, followed by "choose zip from SD "?

While I'm not the OP, I am having the same problem. NookColor 1.4.3
I burned the SD agnostic image to a SD card. Then copied a CM7.zip build to the card. Placed that into the nook, powered on. It just boots stock.
The card shows up in stock OS, has the 5 files(MLO, u-boot.bin, uImage, uRamdisk, cm-7.2.0-encore.zip) that it had when in the PC and 3 added directories from the nook upon boot(B&N Downloads, LOST.DIR, My Files)
Have tried lots of other files on the SD card. It always boots stock. Tried different SD cards(SanDisk 8GB Class 4, Generic 1GB)
Have EVO rooting skills so I understand what I'm doing. This is my first Nook.
This thing is crap with locked app store. Need to root to either install my apps on stock or run full blown android. Dual boot would be ok too, but I don't care about warranty. I just want something to work.
Are you sure you have a Nook Color? You could have a Nook Tablet, they look just like a Color but have a silver bezel instead of black. The model number on the Tablet is BNTV-250. These cards will not boot on a Tablet.
