Hi, I have Librem 14 (coreboot/seaBIOS) with Samsung 970 Evo Plus 2TB SSD. I installed Guix manually, the disk has MBR partition table and these partitions: /dev/nvme0n1p1 - 1GB, Linux (83), bootable /dev/nvme0n1p2 - 1.8TB, Linux (83) The nvme0n1p1 (/boot) is unencrypted with ext4: mkfs.ext4 -L system-boot /dev/nvme0n1p1 The nvme0n1p2 (/) is encrypted using LUKS and on top is ext4: cryptsetup luksFormat /dev/nvme0n1p2 cryptsetup open /dev/nvme0n1p2 luks mkfs.ext4 -L system-root /dev/mapper/luks mount LABEL=system-root /mnt mkdir /mnt/etc /mnt/boot mount LABEL=system-boot /mnt/boot herd start cow-store /mnt The relevant part on /mnt/etc/config.scm: (bootloader (bootloader-configuration (bootloader grub-bootloader) (target "/dev/nvme0n1"))) (mapped-devices (list (mapped-device (source (uuid "...")) (target "luks") (type luks-device-mapping)))) (file-systems (cons* (file-system (mount-point "/") (device "/dev/mapper/luks") (type "ext4") (dependencies mapped-devices)) %base-file-systems))) guix system init /mnt/etc/config.scm /mnt Installation is without any errors. After rebooting grub asks for a password to decrypt LUKS partition, then gives me the boot menu. When I hit enter, the laptop gets stuck, I can't do ctrl+alt+f3,f4... only ctrl+alt+del works. Attached are pictures from grub. I also tried to use unencrypted root partition (basically the same as above, but without LUKS) and it works. Thanks, J
