Article: Install Bootloader and Extra to EFI Partition

Yes. I had this working flawlessly up until I did a "Repair Disk" on my system SSD in Disk Utility. Disk Utility wiped my EFI partition as part of the "repair".

  • :banghead:

As an alternative, I've tried to create a real partition on another drive to act as the boat loader but every time the system just loops with the cursor dancing around.

Now I am back to needing to keep that USB hard drive plugged in so I can boot...

  • :eek:

Any thoughts on how to stop Disk Utility from "repairing" my EFI partition during a disk check? Thanks in advance for any help.

I've re-run the procedure and I'm back to booting without the USB hard drive.

  • :thumbup:
I must have been booted into my DR clone of the system disk when I ran the Disk Utility. At any rate, be careful for this case or you'll be re-running the procedure.

Is your Unibeast USB installer drive plugged into the computer?

Looks like we both used the Maximus VI Extreme in our builds... cool. :thumbup:

Well I have scoured the internet and no way does my Win 8.1 computer let me get to the BIOS. Every suggested option I have tried. I have downloaded Ubuntu and it seems that I can boot off their USB OK by pressing repeatedly the enter button on boot. The same procedure, hitting the Enter key whilst booting does not work on the MAC OS USB. Looks like I can load up Ubuntu, and use that to reset the MBR etc and give me some boot choices. Then I should be able to install the Mac OS.

I hate Windows 8.1.

Hi, I just switched from my 280x to a GTX 780. Now I would like to have my extra folder back on my Main HD.
How can I reverse this operation here and make everything normal again?

Thank you guys!

It means I followed the "Install Bootloader and Extra to EFI Partition" guide and got back to booting without the USB drive attached.

If you do a disk repair on your boot disk with Disk Utility (in my case a SSD), when booted from another drive (in this case my DR clone of my SSD), Disk Utility will "repair" your EFI partition and cause your rig not to boot. If that happens, you will need to follow the guide (aka the procedure) to make it boot properly again
