Can't boot - computer doesn't see OSX install

[bonfilio]

Gigabyte UD3P. Everything works 110% 10.7.2 flawlessly.

 

After doing a restore from my backup drive using Carbon Copy Cloner I can't get the system to boot. Once I've restored a backup the only way I can boot is using my USB boot/install disk.

 

Pretty sure this is an active partition/fdisk issue, but I can't figure it out. The only solution I've had is to completely reformat everything from my USB Lion installer, which apparently puts the proper permissions in place to get things working, but really kind of negates the point of having a working backup.

 

 

bonfilio-pc:~ bonfilio$ diskutil list
/dev/disk0
  #:                       TYPE NAME                    SIZE       IDENTIFIER

  2:                  Apple_HFS Mac OS X                999.9 GB   disk0s2

 

 

Is the main drive in question.

it shows me my partition is active.

 

 

Hitting F12 and selecting the appropriate drive doesn't make a difference.

 

Also, this doesn't seem to be a Chameleon issue as I'm not getting to that point in the boot. I'm having the OSX equivalent of 'BOOTMGR missing, press CTRL+ALT+DEL'.
