So i have a windows 8 computer (upgraded to win 8 ) more specifically a Dell studio XPS 9000/435T and it is stuck in a loop. it says Repairing and then diagnosing your PC and then Windows auto repair was unable to repair your PC. i have tried reset option and putting in Windows 8 disk (it has win 8.1) and it says media is invalid try again. even when i got win 8.1 usb it said the same. i tried booting into the CD but it wont boot. i booted into Windows XP CD but then it says windows was shut down to prevent damage. Specs i7 920 2.67GHz 8GB RAM and GT 220. Hard Disk Seagate St1Dm003 1TB something like that. need help asap
