WIN XP message: "Windows cannot read from this disk. The disk might be corrupted or could be using a format that is not compatible with windows." However the same Win 7 installation disc works fine on a VISTA computer.
Any help would be greatly appreciated. I am trying to upgrade both computers to WIN 7 ULTIMATE.
DVD drive functions fine on everything else. I think I finally realized that the problem may be that the WIN 7 ULTIMATE I purchased on EBAY is really a clever fake, after viewing several examples on YOUTUBE. Thanks for your replies though.
