I had my Mac set up with rEFIt and installed Ubuntu 13.04, unfortunately GRUB was installed over rEFIt. I was not expecting this and have since found out that I have no idea where my installation disk is for OSX 10.8. I want to boot to OSX, but I cannot do boot repair using any OSX tools since I have lost the ability to boot to this. Any suggestions?
GRUB lists the Ubuntu options along with Mac OSX 32 and 64bit, neither of which work.
