I'm having a problem. I got my Nook HD replaced by a newone and I just thought to enter my microsd card into the new one but it just stays at the image of cyanogen in a boot loop I suppose. How do I fix it?
If you installed CyanogenMod using the Hybrid method, certain files are stored on the SD card (most of the essential boot requirements, and some other stuff) and the rest is stored on the internal storage. The the two come together to provide you CyanogenMod (internal + SD storage).
Since you've now got a new Nook HD, it will simply not work with the SD card alone (if you had a Hybrid setup previously on your old Nook); since there are no CyanogenMod files on your internal storage. To solve this issue, you may have to boot into ClockWorkMod and reflash CyanogenMod (+ Gapps, and any other zips, such as leapinlar's SD swap etc). Whether or not you will still have your old files, I'm not too sure on. If you used your SD card as storage, you will NOT lose anything on your SD card; however, anything stored on internal will be lost on your new Nook.
Basically, to solve the issue (if you're using a Hybrid set up) may be to flash the latest ROM again; or if that does not solve the problem, completely abandon your current setup, and start again fresh. The latter should prove results, no matter your current setup.
I'm sorry about the issues, and/or if I've misunderstood you. All the best in your attempts/solution.
