I get this message "Windows/System32/Config/System file missing or corrupt" when I try to boot into XP Pro. I tried to use the windows CD to get into the repair console but I get a BSOD error that says Registry_Error. I get the same message when I tried to reformat. I cannot boot into safe mode, last known good config, or regular boot up. Thanks in advance for all the help, it means a lot.

turn off the bios virus scan., how is the cd drive connected to the mobo, did u try to format with the cd?

How do i turn off bios virus scan? CD Drive is Secodary Slave. I tried to reformat with CD but i get a BSOD that says Registry_Error

when your pc is posting you have an option to press either DEL, F1, or F11 to enter setup, press that key then look through the bios for any option to scan boot sector. disable that. I would ale put the CD on the Secondary MASTER and the HDD on the primary MASTER (setting both to master Single) Until you completed the install.

What do you mean by ale? To make CD secondary master and HDD primary master will I have to change any jumpers, or just change IDE cables? Also what do you mean when you say (set both to master Single)? Sorry I am not as good with computers as I would like to be. Thanks for all your help thus far.
