Hi - I have an ASUS V500C laptop that came with Windows 8. My client decides he hates Win 8, so I purchased a Win7 Pro license, hoping that the drivers I need will be around, and may be able to find some substitutions if necessary. I get the drive formatted, boot up with the Win 7 DVD with an external DVD drive, it says to "touch any key to run dvd", I do that , it shows the "Starting Windows" screen, and basically STOPS. Thats it. Ive tested other Win7 DVDs as well as another DVD drive i have, and it does the same thing. The hard drive seems to be ok, being that Win8 was working fine prior to this. Any idea what would cause this?
