If you dont want to mess with making this card and just want me to make it for you and ship it to you, click this sentence.
According to XDA this works on the 8gb nook tablet and the 16gb nook tablet. I have not tested it yet... yet. I have not contributed at all to these files. If you are wanting to donate for the development of these files, do so the the OP on XDA. this file is still in ALPHA testing phase. Proceed at your own risk.
Once I test out the files I will also be offering services of creating this image on 8, 16, and 32 gig partitions with the entire card accessible for both the 8gb NT and the 16gb NT. Not until I test it though and the post will be in the accessories section.
This card should allow you to boot into CM7 without rooting or nulling your warranty on the Nook Tablet. ***no files are modified on the internal SD card***
Hypothetical drawbacks that have not been tested yet: due to the three variations of nook tablets, you may not be able to boot to the SD card without the help of a usb cable or PC as demonstrated with the other root sd cards i have sold. Some people may be able to boot by simply turning on, some may require N and power combo and others may require a USB connected to PC to get it to boot to sd card. I suspect this to be a limitation to the product. You can thank barnes and noble for their poor quality assurance when making the nook tablet...
Files to download
1. CM7 img file for SD
Instructions for windows: (linux instructions in original thread, mac users: just google how to mount an img file to sdcard)
1. Open up Win32diskImager zip and extract ALL files to desktop or folder of your choosing.
2. Unzip and copy CM7 img file pulled from CM7 img zip (4gb file)
3. Use Win32diskimager to write SD card image, by choosing cm7 image and choosing SD card to write it to and click write.
Result will be a 4gb sd card in 4 different partitions regardless of the size sd card you placed in. You can expand one of the partitions to the rest of the sd card and it will allow you to utilize the rest of the card. I have not tested out which one this is but I suspect it is the largest partition that has no data written to it.
If you have performed this successfully, please post back here as a response and tell us:
1. What NT you have (8gb or 16gb)
2. what SD card you used(size and class). Thanks!
3. what proceedure you had to do to get your tablet to boot to SD (use usb, just turn on, or key combo)
I have a 16 GB Nook Tablet. I tried various procedures prior to coming upon this thread.
Every thing else would only bring up the factory restore menu.
I used the Win32DiskImager on Windows 7-64
I used an Sandisk 8GB Class 4 card
I reset the nook to FACTORY 1.4.2
My nook booted directly to the SD card, with just the power switch
It flashed brightly before displaying the splash page.
A power cycle boot brings up sdcard CM7
A warm reboot brings up the factory reset / boot menu which allows you to switch back to
stock interface without removing the card.
To return to CM7 on the card you have to power cycle the NT.

i just tried this with a 16gb class 6 card and it worked great, but it didnt switch back and forth between on board and off board alright... it ruined the card and resulted in a black screen of death when i tried to switch. I need to do some more testing to figure out why
Well, it worked! There was some doubt there for awhile as I thought I'd ruined the sd card when I tried to repartition it after I imaged CM7 to it but after a few (or many) attempts I got that fixed.
The first time I booted with the CM7 sdcard the skateboarding Android popped up and then a black screen (expected) after about 10 minutes I popped the card out and reset it and then booted again. This time it worked.
I'm up and running. Got the WIFI working, added my google account. One thing I haven't figured out how to do is to reload my back-up from Titanium Bankup. That's sitting on the other sdcard and the CM7 card needs to stay in the NT. Another issue I'm seeing is the google recognizes me, my calendar and contacts automatically synced up but when I go to the market none of my apps are listed. Haven't tried amazon yet. I'll let you know how that goes.
I must be dense/ I can get this work just great but any resizing of the 1st or 4th Partition (tried it both ways) breaks it on boot (no splash sceen, nada) Suggestions?
