Chosen Solution
I want to boot in Safe Mode but no disk will show up in my “Choose Startup Disk” menu. I went through and (First Aid) repaired all Disks in the Disk Utility but I still can’t get them to show up. I have these Disks currently in Disk Utility: Internal = APPLE SSD AP0512Q Media ^ Container disk3 ^ Macintosh HD (named) Disk Images = Apple disk image Media ^ Container disk5 ^ macOS Base System This customer just got this new MacBook and I’d love to give them hope!
What if you Option boot and try to Reinstall the OS. Disk Utility is seeing Macintosh HD so something is there. I would try reinstalling the OS and see what that does. How to Reinstall macOS on an M1 MacBook Air, M1 MacBook Pro, and M1 Mac Mini
