I installed grub on a EFI based system. So I have the EFI partition on /dev/sdc2 and my LUKS container in /dev/sdc5. I have only one linux partition in the LUKS container. So even /boot with the stage 2 of grub is encrypted.
When the system boots the EFI boots the grub entry and grub stage 1 loads. This tries to open the LUKS container in /dev/sdc5 and wants a password.
This is the time where I want to have a german layout instead of the english-us one. I know how to change the layout in grub stage 2 but how do I change it in stage 1. Is this even possible?
OS is Debian Jessie.
