Quadruple Boot into Nook OS, CM7, 9, and 10 on Nook Tablet
Booting into multiple versions of Android have become kind of quite common around these parts. There are many devices that can dual boot. Usually it’s in the form of an OEM-skinned ROM and a AOSP-based ROM, which users choose to flash. Recently however, developers have been pushing a little further than that. The HTC HD2 received triple boot, where it could boot not only into three different ROMs, but those were actually different operating systems. Now, the Barnes & Noble Nook Tablet can quad-booting.
XDA Forum Member malloneem wrote a tutorial that allows users to flash up to three ROMs on a SD card, while leaving the stock Nook software on the tablet’s storage. That’s four total bootable ROMs. As malloneem explains:
This is a guide to use with Windows to create a 3-Boot SD card for a nook Tablet 8GB or 16 GB. After you are done you will be able to choose to boot into your regular nook OS or choose between CM7, CM9 or CM 10.
As stated by the developer, this can only be accomplished through Windows at the moment. Users will be run through the partition process in such a manner that three ROMs can run from it. That is really the majority of the tutorial. Then it’s a matter from grabbing ROMs from the various ROM developers and installing them all. It’s a long and tedious process, though, so make sure to have an afternoon to dedicate.
