Ubuntu – Ubuntu installed GRUB over rEFIt


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.

Try holding down the Option key while powering on the computer. This should enable you to boot OS X, from which you can re-install rEFIt (or install rEFInd instead, if you care to upgrade, since rEFIt is no longer being maintained).
