Recently, I decided to dual boot my Mac with Ubuntu 12.04 beta2. Not sure what I changed, but now I can't boot into Ubuntu, a live cd, or OS X. When I try to boot Ubuntu in recovery mode (as for some reasion I can access the grub menu), the last two lines say:
[ 1.160316] BIOS EDD facility v0.16 2004-Jun-25, 0 devices found [ 1.160381] EDD information not available.
Am I able to recover my computer?
