I have a MacBook Air that has suddenly stopped booting at all. I booted into recovery mode and see the harddrive fine in Disk Utility. The partition is there as well marked: Mac OS X Base System. I can verify this partition with Verify Disk. The disk verifies just fine and appears to be ok.
However when I go to set it as the startup disk (in Choose startup disk), it doesn't show. I get a blank list.
What gives? How can the disk be seen by Disk Utility but not Choose startup disk?
Other things attempted:
- ⌥⌘RP to reset PRAM (reset the box)
- Shift on boot for safe mode (did nothing)
