i just aquired a used laptop that has a cluttered up version of windows me. i want to start over and wipe out the harddrive and install another os. either linux 9because its free) or i have a 98 laying around. do i need a program to do this. i thought there was a way by rebooting in dos mode and typing "f/" or something like that. its an old toshiba 2100. 400 mghtz. 128mb ram. how hard will it be and how much can i update this.
