I tried to install Windows 7 x64 on a machine that I already had Windows 7 32 bit successfully installed. But the 64 bit install failed with message "A required cd/dvd driver is needed...." . Removed everything from the motherboard except one hdd/sata and tried installing from usb image too and the same dreadful cd/dvd driver needed message stops the install.... any clue ?
