Hello. 

The SSD partition table is MBR, and all three partitions contain an
ext4 filesystem. I don't see how it could be a missing module issue,
and even if it was I'm not sure which module would I have to choose
since Guix is already installed on an MBR partition table with ext4
filesystem and it boots just fine.

This looks like some sort of obscure and bizarre bug, as
everything I'm seeing tells me that the SSD filesystems should be
recognized without any issue by Guix GRUB, but they aren't.

I ran e2fsck, lsblk, blkid and fdisk on a booted system to verify
that everything is fine with these partitions, no sign of anything
unusal...
