Hi I am using this to install on a laptop that has XP. I downloaded the file on that PC and then created a bootable flash drive. I am waiting for it all to load onto the flash now my question is do I just plug it in to the pc as is with XP on it or do I have to do wipe it out first?? Please help me I have been messing with this machine for 2 1/2 days now, thats why i decided to put windows 7 on it.
