When UEFI Secure Boot is enabled, which it should be if available, especially on a system with Window on it, you need the distro signed shim.efi and grubx64.efi on the EFI system partition. If you use grub-install the signed copy is wiped out, and the system won't boot until you disable Secure Boot. So in a UEFI Secure Boot world, grub-install (and grub2-install) is obsolete. This bug is still annoying, and I wonder if it should be a blocker bug. https://bugzilla.redhat.com/show_bug.cgi?id=1170245 -- Chris Murphy -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
