[gentoo-user] grub2 on macbook pro

[Douglas J Hunley]

I'm completely stuck on getting Grub2 to work with the EFI on a new
macbook pro. I have grub2 emerged w/o issue, and efibootmg as well.
I've looked at both the Grub2 wiki and the Macbook wiki and the
various directions are just /not/ clicking for me. Anyone have any
clue how to actually get the EFI on macbook to boot Grub from
/dev/sda1?

Here I have two macs with linux (gentoo), both are running refit
(http://refit.sourceforge.net/) to boot properly.

There is a catch22 - you have to be booted via EFI to install EFI.  To
do this, I had to boot using EFI (I think it was fedora) and use that to
set up with efibootmg.

I used System Rescue CD, and the whole process of setting up EFI booting
was a lot less scary than the interwebs make out.

System Rescue CD made things so simple

I've found that most problems with EFI and such are easier to resolve
when using an optical drive. If you have the new MBP, then you should
consider purchasing a cheap external drive and try using the Gentoo CD
[1].

Have you made your EFI image with grub-mkimage?

Once that's done tar up your GRUB directory and extract it to /efi/grub
in Mac OS.  I have rEFIt installed as well so I can select EFI GRUB
among other boot options (like legacy BIOS emulation mode and Mac OS).

blee@supra /mnt/macos/efi $ ls
grub  rEFIt License.rtf  rEFIt ReadMe.rtf  refit  tools
blee@supra /mnt/macos/efi $ ls grub/grub.efi grub/grub.cfg
grub/grub.cfg  grub/grub.efi

I'm not dual-booting. OSX is /gone/

Thanks for the input everyone. I figured it out eventually and will be
posting a writeup to my G+ during lunch today to describe the process
since I had several people interested in the outcome that are not on
this list.
