Xp Home edition giving big trouble. My father in law rather foolishly likes to re install XP every time he gets the the most smallest of problems with his PC. I have told him time and time again that he will cause great damage and should only re-install windows if he is absolutely desperate. Now it would seem my words have come true and his system is totally corrupt. I want to reformat the HDD but cant. In windows 98 I used to do Fdisk. WHat do you do with XP.?? I cant do it by starting windows and right clicking on C: and choosing format, because it just tells me that I cant do that whilst other utilities are using the drive. Any Ideas how I can manually do it. Fdisk was a very usefull tool on 98'... why you cant do it anymore is silly. Please help.
