hi, something went wrong with my fathers computer and now he can't even go into windows (he's running windows 98). he wants to upgrade to xp but he doesn't know how to reformat his hard drive. can he just put in his windows xp cd and reformat from there or does he have to do the whole fdisk stuff. and if he has to reformat his hard drive by himself, can someone explain the specific steps of how to do that so i can tell him? thank you all in advance!
