Debian on MacBook

There is a very good blog article which only lacks some minor information:

This article adds the required information on how to get grub-efi to work in case of troubles.

After Debian installation re-insert Installer CD/DVD and boot from it.

Choose the rescue menu and select your root filesystem device (the device where "/" and not where "/boot" is on).

Check for mounts:

mount -a

If this command shows you that /boot is mounted try to verify:

umount /dev/<device where /boot is on>

If this gives you an error, than you know for sure that the information was in /etc/mtab but the device was not mounted.

Now mount your /boot device again:

mount/dev/<device where /boot is on> /boot

Create efi directory:

mkdir /boot/efi

Mount your hidden efi partition

mount /dev/<hidden efi partition> /boot/efi

Load efivars module

modprobe efivars

Install grub-efi

apt-get install grub-efi

Rerun update-grub and grub-install

This will put a new directory in /boot/efi/EFI/ with name debian

Unmount all partitions, exit the terminal and reboot the system.
