Updated to 10.8.4 - won't boot off the drive.

Updated to 10.8.4 - now X79 won't boot off the drive.

I updated and I can't get it to boot off the drive.
If I boot from another working drive of 10.8.2 and MB 5.21
I boot up into the bootloader and then select my 10.8.4 drive it will boot (with no flags)
but it will not boot by itself......

Should I use MB 5.43? any wisdom that can be shed on this dark situation....Thanks guys.
