Explanation

If the SATA controller port to which the DVD-ROM drive is connected is disabled in BIOS/UEFI settings, the system will not detect the drive at all, making it completely unusable in the operating system. This is a valid hardware-level cause of the reported problem. Media Player not being installed would prevent media playback but the drive would still appear in File Explorer and function. DVD-ROM drives use generic drivers provided by the OS and rarely require separate driver updates; Windows 7 handles optical drives natively. The DVD drive's boot order setting in BIOS only affects whether the system attempts to boot from the disc - it has no effect on the drive's availability during normal OS operation. A disabled SATA port, however, means the device is invisible to both the BIOS and the operating system.
