Hi Peter, This is indeed not nice. Guix does not provide a useful package that would reinstall boot configuratipn because boot configuration is managed together with the rest of the system configuration.
You need to update your /etc/config.scm to declare more entries, and reconfigure. Here are the relevant chapters in the manual: https://guix.gnu.org/manual/devel/en/html_node/Bootloader-Configuration.html (in particular, see menu-entry) https://guix.gnu.org/manual/devel/en/html_node/Invoking-guix-system.html (see reconfigure) Of course this is only a workaround I'm proposing, we should fix the installer to detect other OSs.
