My Guix GRUB EFI boot entry is also now gone.  Fortunately, I had
another GRUB installed with a Guix entry, so I can still get into Guix
(an older system generation, though).

What are the consequences of that?  I'm afraid.  Would it make the still
existing EFI boot entries go missing?

I think I don't have a Guix image.  Would a Trisquel image do?  (I guess
yes.)

I don't care about GRUB's look, I just need to get into Guix.
