I recently ran DiskWarrior on my Mac Pro running 10.7.5 for routine maintenance. After loading the DiskWarrior CD I rebooted with option key pressed and I got a strange startup manager. Instead of the usual labels for bootable volumes, which are just volume names, they were labeled as "efi bootable volume" (or partition, can't remember) and some id code jargon. I clicked the one that I though was the DiskWarrior volume and was right, so just ran the maintenance and everything checked out fine. Today I thought I'd try to reproduce this by booting up the same way and I found that the startup manager screen didn't present itself at all, but the system booted up from the Diskwarrior CD without giving me a choice. Both times there were two bootable drives, "Boot" and "DiskWarrior."
Any idea as to what could have happened here? Could resetting the PRAM possibly help? I doubt it is file damage because DiskWarrior found nothing wrong with the files either time. Any help in avoiding an OS reinstall greatly appreciated.
