A grub2-install based grubx64.efi expects to find the grub.cfg in /boot/grub2/grub.cfg. This OSLoader is not signed. The grub2-efi-x64-2.04-31.fc33.x86_64 based grubx64.efi expects to find the grub.cfg on the EFI system partition inside EFI/fedora/ and this OSLoader is signed. Basically you've stepped through the Looking Glass by using grub2-install on a UEFI computer. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
