I dual-booted my Mac with Ubuntu and it was running fine, I wen't out the office but continued to use it via VNC just to set up my environment, this obviously caused a lot of updates that wanted me to restart my computer (Something I couldn't do as it would boot straight into mac unless someone selected Linux on ReFit). Then there was a power outage causing it to be shut-off one day, I came back into the office today to find that it refuses to boot, I just get a black screen with a flashing white cursor, it does boot into the Mac no problem, any solutions?

It seems to not even get into the Grub loader, as pressing Shift does nothing, I select Linux from rEFit then it goes straight to a black screen with a flashing text input cursor, I can do nothing, only restart and do it all again.
