RE: Boot not possible after BIOS update
Same problem here. My laptop is about 4 months old, never had problems. Dell forced the update to BIOS 1.2.2 -- and BOOM. No boot device found. I got in by pressing f12 and getting into the boot menu and booting to the UEFI partition (or something like that). Now I'm backing everything up, and will be attempting to roll back my BIOS to something older.
