I got a similar message asking for the CDROM driver on Windows Setup. I thought this was interesting since I was using the drive to install from DVD! Turned out it was a bad burn. I redownloaded the ISO file (just in case there was something wrong with my initial download), and chose the slowest possible burn speed to resolve the issue.
