alright heres the scoop my comp is down sadly and it wont load up windows or even safe mode so i want to format my disk or reinstall xp see if that works but the disk wont showl up since i have a os installed and i cant bring it up... o and i guess i should tell u it trys to come up but i either get the evil blue screen or it restarts ne ways, so what im asking is how do i reformat or even format a hd without actually going into a os or even going into safe mode if i have xp installed on the disk?? please help
