Hey, I'm getting ready to switch over to WinXP from Win98 SE and was wondering if I should go with the WinXP Pro Full version or if the upgrade would suffice. I want to do a clean install and want to do all the partitions and formats using the WinXP partitons and format types. If I buy the upgrade will I have to install Win98 and then install WinXP over it or does WinXP simply ask for a previous OS disk before installation? I'm just basically asking if I can do a clean install of WinXP using the Pro Upgrade. Thanks for any help you can give me.
