Ive just installed a fresh new instance of arch-linux on my old iMac. Unfortunately, the apple default efi bootloader isn't be able to load the efi-entry.

My partitions are:

#1 EFI
#2 Mac OS X
#3 Rescure Mac
#4 boot (my /boot-partition for linux)
#5 encrypted

partition 5 is my enrypted partition, which contains the lvm volume-group which contains 3 partitions (root, home and swap).

I've mounted efi (#1) on /boot/efi. In boot, there is my kernel-image vmlinuz-linux. In /boot/efi/loader/entries/arch-encrypted.conf, I've edited the file so the option "linux" has /vmlinuz-linux. Now it looks like that:

title          Arch Linux
linux          /vmlinuz-linux
initrd         /initramfs-linux.img
options        encrypteddevice=UUID=<UUID of partition #5>:lvm root=/dev/mapper/vg--base-lv--root quiet rw

But now when Im rebooting my system, arch isn't booting but an error message will get printed containing "\vmlinuz-linux can't be found".

I guess this is so because the linux-image is located on an different partition but this efi-entry points to the efi-partition where the entry is located itselv.

Can anybody help me with this please?

You probably answered your own question. The paths in the .conf file are relative to the root of the ESP, and no other partitions are known at this stage. vmlinuz-linux (et al.) are put in /boot by pacman, and if /boot/efi (the ESP) is mounted under /boot they are on different partitions.

You could merge the partitions so that the ESP is mounted on boot. For other solutions, see EFI System Partition.

  • Thanks for the answer! So would it be possible to format the /boot-partition as vfat/fat32 so that efi could get installed as well as the linux boot images? – Marc M Oct 6 '16 at 10:39
  • This article and several others at Rod's excellent site might help you understand what's going on. – Michael Shigorin Oct 6 '16 at 11:03
  • Yes, you can of course re-format the /boot partition, but even simpler is to move the files in /boot to your ESP and mount that partition as /boot. – Johan Myréen Oct 6 '16 at 11:21
