Update: restored BIOS to default and rebooted, and recognizing SSD again
I updated OS to Windows 11 22H2 (I think) this morning via Windows Update and while restarting automatically during the update, it took me to an error page rather than the OS, where it said "no bootable devices found". It appears to not be recognizing my SSD during the update. I've tried safe mode, selecting drive (none found), reinstalling Windows (error, unable to complete), resetting computer, restoring from recovery partition, uninstall last update, all via the recovery blue screen, with no luck. I don't have a recovery drive as I assumed the recovery partition on my SSD was sufficient - maybe not. Any advice appreciated.
