Dual booting on Android devices isn’t the newest technology out there, but whenever it gets ported to a phone, it’s a pretty exciting experience. So what does that say about triple booting? That is even more exciting, for one thing.
XDA Senior Member racks11479 has posted a method that will, once installed, allow users to boot into CyanogenMod7, CyanogenMod9 and stock on the Barnes & Noble Nook Color. Simply boot into CM7, then reboot to get into CM9 or power off and power on while pressing N to get to the boot menu for stock.
The process is relatively simple for those who own the Nook Color. You simply follow the same directions you normally would if you were to burn a NookieFroyo SD card from NookDevs.com, which racks11479 has been gracious enough to link to in the process. After that, there’s a short installation process, including an optional install of a Supercharge script, and you’re reading to start triple booting. Additionally, it appears that racks11479 consistently updates the thread and method so you can be sure that what you’re using is current and will likely be updated again.
For those who want triple booting goodness on their Nook Color, you can find download links, the full instructions, change log and all the additional options in the original thread. As per the norm, don’t forget to make a back up just in case!___________________
