hi, i was wondering if u could help me, my lil bro's computer is hacked or something, his OS is windows xp media center edition 2005, and i read that i can completely erase his computer by restarting it in MS-DOS mode? i cannot find out where it says "restart in MS-DOS mode" option in the shut down windows dialogue box, all i really need to know is how to restart the comp in MS-DOS mode so i can erase everything, get back to me if ya can please. thank you.
