Trying to install Windows 7 home premium....getting error This installation disc isn't compatible with your version of Windows. To upgrade, you need the correct installation disc. For more information, check your computer's system information. To install a new copy of Windows, restart(boot)your computer using the installation disc, and then select custom(advanced). I currently have Windows XP media center edition 2005. Fry's sold me the oem version telling me it would work and would be cheaper for me. When I try to boot with the disc in it shows black screen and in the corner says boot with disc and when I hit enter it just comes up to the regular startup screen for windows xp.
