scratched or not original CD, missing HDD drivers and/or driver floppy.
Search on Windows fora please.
The CD is fine I used it couple minutes before I used it on the Dell optiplex sx260. I also check it for errors and scratches I even check the ram, the Hard drive works fine because it shows up and even lets me partition it. The only thing its not letting me format. keeps saying updating after I select for formating the drive is says updating as if its searching for something then shows a blue screen of death.......
