I've had PC's lose the assigned boot drive in the BIOS, with no drive detected in the BIOS, after a Windows update.

As said, a dead CMOS battery could cause this.

Worth a check to see if the disk is actually detected in the BIOS. If it's not seen, try to manually select the disk in the boot menu area.
