Default [Q] Help with my nook!

Hello, today I saw that my nook has this problem, I think it had it since a while, but today I started to mess up with it.
It has Cyanogenmod 7, but I don't know what's happening.
It is stuck on this screen:

I was planning to use Cyanogenmod 10... but right now I have this problem.
Does someone knows how to solve this?

--Update-- Today, I tried to turn it on differently, I pushed all the buttons at the same time, and instead of "Loading" it says "Booting into recovery" with a micro SD card into it, then when I removed the micro SD and tried again, it says "booting into alternate..."
Should I try to put CM 10 on it right now?
