[SOLVED] Full disk encryption with BTRFS on UEFI/GPT

Hi there

I want to install Arch on a Laptop running in UEFI mode, with GPT partitioned disk, full disk encryption by dm-crypt and BTRFS formatted partition. Following https://wiki.archlinux.org/index.php/Dm … .28GRUB.29 everything works fine until I should mount (nonencrypted) ESP to (encrypted) /mnt/boot/efi. Then it tells me "mount: unknown filesystem type 'crypto_LUKS'". I know, that the described steps works if you do it on a LVM/EXT4 setup but that's not what I want

I tried with encrypting ESP before, but then UEFI couldn't find GRUB at all and I was stuck with "There was no bootable device found".

Isn't there a way to encrypt bootloader as well on a UEFI system and only with BTRFS (no LVM)?

Any help appreciated!

After all I found the solution

Just format the ESP as you should and everything works:

mkfs.fat -F 32 /dev/sda1
