How do I reformat one of my computers? Currently, the OS is XP Media Center,
and I have a new full version of XP Pro which I have tried to install, but
after typing in the authorization code, the reply comes up that the code is
incorrect. I have already verified that via Microsoft that my OS CD & V-Code
is valid and correct... but in order for the install to continue, I would
have to reformat the computer; of which I have never done.

Can anyone help? I would greatly appreciate any instructions how to
reformat so I can install XP Pro. (I do not want to have duel OS, only XP
Pro)

Thank you...thank you!
