Here you say "change booting method to Legacy" which implies you *can* interrupt booting and go into firmware setup. Could you clarify? If you *can* interrupt booting and go into firmware setup at this point - how does UEFI boot menu look like? Does it have entries for Linux? Does you system offer possibility to run EFI shell? _______________________________________________ Help-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-grub
