Ok I installed windows on my machine and I did all the updates did everything then clicked retstart after intalling the drivers. It started to boot but now shoes 'Windows could not start because the following file is missing or corrupt: system32\DRIVERS\pci.sys You can attempt to repair this file by starting Windows Setup using the original Setup CD-ROM Select 'r' at the first screen to start repair.' Okay so I restart and put the disc in.. screen comes white I hold down R the same message comes back up.. it doesnt do anything. Help? Edit: I just tried a USB keyboard with the disc inside and holding down R but no luck.. the little lights on the caps lock and stuff don't even come on.
