4solace - it is recommended that you buy the dual-boot product pre-installed on an SD card. If you had an SD card, you could buy the download and load the software on the card yourself. This allows you to boot either into Nook mode or AFN (KitKat) mode (which is what provides full table functionality).

Periodically you should shut the tablet down, remove the SD card, use the card reader in a Windows PC, and run a program to capture a full image of the entire SD card. (use a free program called Win32 DiskImager to do this.)  A full backup of the SD card running the AFN product will capture all settings, programs and data stored on it, and a restore will provide the identical configuration in place at the time the backup was created.

I realize that this isn't step-by-step, as I do not have a Nook to provide such steps but this should accomplish what you want to do. And it should be pretty straigh forward.
