Seems to be a common issue. Bios has nothing to do with (normally) the OS. In some odd cases you don't need bios to see all drives but you need it to see the boot drive.
See web pages on how to fix this issue. I think it ends up with a get new motherboard or ssd or both.
If you think it is possible that linux has somehow changed bios settings then be sure to try some different or older distros.
Guess it can't hurt to change the cmos battery.
