follow up: well... i'm bummed now. i tried installing it with my dell's OS (win xp home) which is a new, unscratched disc. but i have the exact same error.
STOP: c0000221 Uknown Hard Error
I don't know whats wrong. i suspect it may be the CD drive, because i am unable to INSTALL games or anything off of it when im in windows. i can burn things to it okay, and i can copy files from the CD drive to the desktop okay, but i always get errors when i try to install something directly off the CD drive.
i installed xp off of it on my 180 GB drive okay today though..
edit: i stole my dad's CD drive out of his computer and so far its working. windows sees my two drives as one, and its formatting right now. ill keep you updated.
working. i installed firefox and graphic drivers from inside windows on my raided hard drives. i looked at drive C:\ and saw 68.9 GB. it workkssssssss
