Installed the software and windows XP SP2. Was running XP fine for a while with no problems, but the computer crashed and I was forced to reset the machine. I turned it on and got the folder+question mark of death. "No problem, I'll just reinstall the OS or repair the hard disk." WRONG! The hard disk is gone. The computer can't recognize it at all, won't allow me to install from the DVD, can't target disk mode it, nothing. Simply gone. I'll be taking it to the Apple store tomorrow to see what else can be done... Always back things up when trying out new software!
