No because there is no EFI partition. If I create one and restart the installer, then it is *not* mounted either, only /mnt/boot/efi later during the install. (I believe since the installer is installed as on an external medium, it does not need an EFI partition.) I had booted the install image via UEFI boot and had expected auto partitioning and the default configuration to do the right thing. > If it were EFI, it would be a GPT partition table, not a DOS one. Thank you for explaining. If Guix defaults require GPT on EFI (according to <https://wiki.archlinux.org/index.php/EFI_system_partition#Create_the_partition>) some computers apparently really do not support dos partition tables for the EFI system partition), then I think gnu/installer/newt/partition.scm should disallow selecting a DOS scheme when auto partitioning the entire disk.
