Install grub-efi-ia32 and run grub-install. Mount the required partitions and chroot into the new elementary OS installation. Now we have to fix the bootloader manually. After that the installation from the wizard is complete.

/dev/mapper/apple-root: ext4 partition mounted at /.

/dev/mapper/apple-home: btrfs partition mounted at /home.

Now you see that the installer sees the partitions we just created. At the “Installation type” screen choose “Something else” once again.

Now run through the installer once again. You’ll see it also created some device symlinks in /dev/mapper. We’ll create a 10GB root partition, 4GB swap partition and the rest is for the home partition. Now execute the pvcreate, vgcreate and lvcreate commands.

As you can see /dev/sda3 is encrypted and referred to as /dev/mapper/sda3_crypt. This is not possible to configure this via the installer. We just quit the installer, because we want to create 3 partitions in the encrypted sda3_crypt for the root partition (/), swap partition and home partition (/home) using LVM2. Change this partition and configure it to not format it. The installer tries to be smart now, by marking sda3_crypt to be formatted as ext4.

To be able to boot this ISO from a USB stick on a MacBook, you have to create FAT32 formatted USB stick which contains an EFI/BOOT/ folder, with 2 files in there: Creating a MacBook compatible bootable USB stickįirst of all I downloaded the 32-bit ISO of the latest elementary OS release (Freya). I’d like to explain how I installed elementary OS on my MacBook including full disk encryption. But I was interested in this lightweight Ubuntu based OS to replace OS X on my MacBook. Normally I use Debian with i3 or sometimes Gnome3. Lately I stumbled upon this “Linux Sucks” YouTube video, which showed the enormous growth of elementary OS on in the past years.

What always frustrated me a bit is that this MacBook wasn’t 100% capable to show 720p YouTube videos. Now almost all videos are available in >720p format.

Along the way I upgraded it to 2GB RAM and gave it a fantastic boost by replacing the HDD by an Intel 320 Series SSD.
