[Q] Recovery glitch after installing rom topic

When i was installing the new nightly of CM11 on the nook color, i ran into a funny glitch or something along the lines of that. After i installed the new ROM and the rebooted after the 1st screen splash instead of going on into the ROM like normal it takes me back to the recovery, i retried like rebooting 20-30 times but no luck, i tried choosing to boot the ROM but it took me to the recovery, i tried to reinstall the ROM but still the same problem is happening. and clue to whats going on?:(:(:(
