Okay, so my Dell Dimension 9100 seems to be stuck at that Windows XP screen. It will NOT allow me to start in safe mode, and when I choose "start windows normally" or "last known configuration" nothing happens. I tried to start in safe mode countless times and one of those times, I got a blue screen with an error of "UNMOUNTABLE_BOOT_VOLUME" I ran the hard drive diagnostics which came back as "Fail – Return Code:7" on Drive 0 and of course I have no idea what that means. I haven’t installed any new software. Any help on the matter would be greatly appreciated. Thanks.
