I'm trying to boot off of a thumb drive which has an OS X recovery image but am unable to get it to be recognized.
I'm pretty sure the USB stick is written correctly (GUID partition table, Mac OS Journaled file system, etc). I created it through the Restore menu in Disk Utility. It mounts exactly as my original disk did (I would normally use my Snow Leopard disk but I recently moved and am unable to find it).
When I open up the 'startup disk' menu in the settings, I noticed my only options are Network Boot and my current hard drive.
How can I get it back so I can boot off of the USB drive?
