Hello Thibaut,
Even in that code that you comment out it is using the probe to find the
uuid. If it finds the uuid i wonder why setting it can not find the uuid.
less -N /usr/lib/grub/grub-mkconfig_lib
127 # If there's a filesystem UUID that GRUB is capable of
identifying, use it;
128 # otherwise set root as per value in device.map.
129 echo "set root='`${grub_probe} --device ${device}
--target=drive`'"
130 if fs_uuid="`${grub_probe} --device ${device} --target=fs_uuid 2>
/dev/null`" ; then
131 echo "search --no-floppy --fs-uuid --set ${fs_uuid}"
132 fi
