i have windows XP and was told by a friend I need a start up disk for my computer. He's gonna clean out my computer and start fresh with the start up disk. However when I searched for XP start up disk at Amazon so many different kinds of software came up. None of which said start up after Windows XP. Can someone explain to me the the difference between XP startup, upgrade, recovery, and what's the other software where you start all over, restore, that's it? Wouldn't they do all the same thing? I'm confused.
