how would i reformat/wipe a Dell L400 Latitude Laptop with a pentium 3 processor... Its got Microsoft 2000 Professional edition on it.... I need to wipe that and put XP or a home edition of 2000 on it... Every time i boot the pc up i come to the gilead log on screen which i can't log on because im not connected to any domain.... ive tried multiple selections in BIOS, ive tried booting up from the CD, but nothing seems to work... any help would be cool.....
