How to Boot to Clockwork Recovery in Nook Color

1. Open the 'Applications' menu on your Nook Color. Tap 'Market' or the application you're using for marketplace access.

2. Type 'ROM Manager' in the Market's search box and press 'Enter.' Tap 'ROM Manager' when it appears in the search results. Touch 'Install' and 'OK' to install this application on your Nook Color. Tap 'Allow' if prompted by a SuperUser request.

3. Open ROM Manager. Select the first option labeled 'Flash ClockworkMod Recovery.' Tap 'OK' and restart your Nook to finalize the installation.

4. Open ROM Manager when your Nook Color boots and select 'Boot Into Recovery.' Tap 'OK.' Your Nook Color reboots once more, this time launching the recovery boot menu before you enter the Android operating system.
