please can someone help i have just brought a toshiba satellite 4080xcdt (a bit old i know but hey) and when booting it says sorry for the inconvenience windows can not load due to pci.sys missing or corrupt. Now i have attempted to fix by putting in a copy of xp but when i get to the windows set up screen there is no option to choose from and the cd does work! Can anyone please help me to get this problem sorted thankyou in advance
