On my HP laptop, “legacy” boot wouldn’t actually do what it’s supposed
to do; I had to use UEFI.

Ah :-/

What’s happening exactly: do you see the GRUB screen? Or do you just
get an error message from the BIOS/UEFI thing? What other relevant
messages or clues are there?

No, I don' t see the grub screen

A black screen with a white writing comes up immediately

The writing says: "Operation System not found"

On the second line, under the capital T there' s a cursor blinking

If I press a key the Bios screen comes back. The Bios screen used to select a boot device

If I select the hard drive where GuixSD should be, the black screen with white writing comes back

And so on
