I installed Ubuntu on a MacBook and everything was working fine. A few weeks into using it I realized that the Mac had a few problems with the keyboard.

I had another MacBook of the exact same model so I swapped hard drives but now the new Mac won't boot Ubuntu or even recognize it.

Originally, after the Ubuntu install I had to boot into the live CD and manually change the boot order with this command:

efibootmgr -o 0,80

However, when I try to do this now it says:

boot entry 0 does not exist

I can see my disk there as /dev/sda with partitions /dev/sda1, /dev/sda2, /dev/sda3 .

Any suggestions on how to get it to boot? Just a note, I am not dual booting this is just Ubuntu by itself.

EDIT

My installation is Encrypted with LVM as well. This may be causing more issues.

  • Not an expert here, but I think that with Macs you also have to resync the partitions again with rEFIt.

Trying to single install on MacBook Pro but won't automatically boot from new OS?

I was able to get it to boot with a live USB's grub menu. However, something went wrong with the rest of the steps and while trying a few other things I formatted my boot partition.

I had to reinstall and transfer my files from backup. Everything is working now from a fresh Ubuntu install.
