ME to XP

I recently purchased a four year old Toshiba laptop running WindowsME on 6 gigs of hardrive space. I want to upgrade to XP, but the XP software is for a new computer, therefore it’s not an upgrade version. I’m guessing the only way to install would be to reformat and start over.

However, I had an old ’95 which I tried to reformat and use XP and when I got all done, the software wouldn’t work and I was stuck with a useless computer I eventually threw out. I don’t want that to happen.

Does anyone know what I should do?
