As this is a “full disk encryption”-scheme which includes /boot, I’m sorry to say, there’s no easy way to change the default keyboard layout from US-qwerty at this early stage in the boot process. At this stage solely grub and not our initramfs/kernel is in charge.
You have two viable options:
- You’ll just have to memorize and input the appropriate qwerty keys for your password, -or-
- change the pw, or add another password to something that works in both layouts.
Sorry,
