Restore EFI boot on MBA after failed Mint17 install [SOLVED]

Post by goinglinux » Thu Jul 03, 2014 12:45 pm

Clem created an excellent tutorial for installing Mint17 on Macbooks using EFI, without rEFIt or rEFInd. "Linux Mint 17 on the MacBook Pro" http://community.linuxmint.com/tutorial/view/1643

I followed the instructions above, and made a mistake during the installation of Mint17 onto a USB stick. Yep, it's a self-inflicted wound! I would like to return the MacBook Air 6,2 to the original Apple efi booter loader. (I.e. remove Grub completely.) Any ideas on how I can reverse this? (I have searched for a solution in the usual Mac support places to no avail.)

Right now if I power on normally, because of the failed installation, it will not boot into anything. I get the Grub 2.2 prompt, not the menu. I can type "exit" at the Grub screen and boot into OSX. I can also boot into OSX if I hold the option key during power on. Opt-R does not boot into the recovery partition, just the Grub prompt.

Of course I don't have a system backup prior to the problem. :(

Any and all advice is welcome.

Turns out I was over-thinking it. The solution:
  • In the System Preferences, select Startup Disk
  • Select the icon for Macintosh HD
  • Click the Restart button
The selected disk is set as the default boot device.
