I have a ASROCK X79 Extreme9. I have a kingston SSD and a CDRom attached the the SATA ports. Both devices show in BIOS including in the boot menu. I have the SSD set to ACHI and others set to IDE.
When I bring up the boot menu, I select the cdrom and hit enter. I receive a message, "Reboot and Select proper boot device or insert Boot Media in Selected Boot device and press any key". When I hit any key, I continue to receive the same mesage. I have tried two different Windows install cd in the cdrom drive.
