Hi there, I'm trying to upgrade from windows XP to Windows 7 Ultimate. After I boot the installation and chose a custom installation, it asks me to select a drive to install windows 7 onto. Only problem is the program cannot find any drives... It then gives me an option to browse my drives for the drivers. I tried browsing the Installation Files under the E drive but that didn't work out too well either... Does anyone have any tips?! Much Appreciated, thanks.
