Instead I see the UUIDs > 1970-01-01-19-49-46-83 for partition 1 and 3495-32E0 for partition 2. The option in the GRUB menu uses the “DCE” format for the UUID, but if you convert it to an ISO-9660 UUID, it looks almost the same: --8<---------------cut here---------------start------------->8--- scheme@(guile-user)> ,use(gnu system uuid) scheme@(guile-user)> (string->uuid "31393730-3031-3031-3139-333534353239") $60 = #vu8(49 57 55 48 48 49 48 49 49 57 51 53 52 53 50 57) scheme@(guile-user)> (bytevector->uuid $60 'iso9660) $61 = #<<uuid> type: iso9660 bv: #vu8(49 57 55 48 48 49 48 49 49 57 51 53 52 53 50 57)> scheme@(guile-user)> (uuid->string $61) $62 = "1970-01-01-19-35-45-29" --8<---------------cut here---------------end--------------->8--- The ISO UUID is computed in a deterministic fashion. Are you sure you’re looking at the same ISO? For example, if you pick <https://alpha.gnu.org/gnu/guix/guix-system-install-1.2.0rc1.x86_64-linux.iso.xz>, it boots just fine. In the GRUB menu entry (type ‘e’ in the menu), you can see both the DCE UUID for ‘--root’ and the ISO UUID for ‘search.fs’, which are actually the same. HTH! Ludo’.
