It is near impossible to brick the Nook Color. Since you can at least get it turned on you should be alright. but, Gbatemp isn't the best website to be asking about this. i doubt many users here have a Nook Color. Anyway, you should head on over to this link.

This is the place where all the hacking methods are developed for your Nook Color. There are plenty of people there who should be able to help you out. Just be good with your grammar and try not to sound like to much of a noob and maybe they won't yell at you.

I installed the image file on the memory card. Took it out then put it back in like it said to. But now my computer can't find the memory card. Or any other memory card for that matter. In other words the card won't show up on my computer anymore. What happened? I'm so disgusted right now
