BEFORE YOU START, you'll need a MicroSD card with an MicroSD card to SD adapter. You'll need at least 128MB of memory on it, but it's recommended to carry a 1GB. (Besides, who carries a 128MB SD card in today's day and age?).
Step 1: Charge up your Nook Color and then power on your Nook Color to register your Barnes & Noble account on the device. (Make sure you register, as you will not be able to do this after you root your Nook Color).
Step2: Mount the SD card to your Windows PC and make sure you format/erase everything on the SD card and remember the Assigned Letter to this SD card.
Step 3: Download this program called Win32DiskImager.
Step 4: On your Nook go to, "Settings" -> "Device Info" -> "About Your Nook Color and Check Software Version"
Step 5: Download this program called Auto Nooter (by GabrialDestruir). This program creates a bootable image on your SD card for booting your Nook Color. You'll have to download a specific Auto Nooter version based on the version of your Nook Color.
Here's a small table to figure out which to download:
Nook 1.0.0 -> auto-nooter-2.12.18.img.zip
Nook 1.0.1 -> auto-nooter-2.12.25.img.zip
Nook Later Versions -> NookDevs guide
Step 6: After downloading the appropriate version of Auto Nooter, open Win32DiskImage.exe
Step 7: Navigate to where the Auto Nooter file you downloaded is located.
Step 8: Click the Drop-Down menu and select the assigned letter to the SD card.
Step 9: Click "Write". The program will format the SD card and copy the bootable image to the SD card.
Step 10: Remove the SD Card from your computer.
Step 11: Hold down the power button on your Nook Color and Power Off.
Step 12: Insert the SD card into your Nook Color.
Step 13: Plug in the Nook Color to your PC via USB. Your Nook Color will now boot.
Step 14: If using Auto Nooter for Nook Color version 1.0.1 or later, your Nook Color will reboot after the root process and proceed to boot normally.
If using Auto Nooter for Nook Color version 1.0.0, once the device shows in Windows wait at least 5 minutes for the scripts to complete and then discounnect the USB cable, remove the SD card, and hold down the power button for 15 seconds to boot your Nook Color. You'll see it boot to the new boot sequence after the Nook Logo.
Step 15: After booting, you'll notice the Android logo. Proceed with the setup process and register your google account. You have successfully rooted and installed Android OS on your Nook Color! Congradulations!
