Right and this cannot be done with a USB stick imaged using dd (or variant including Fedora Media Writer) from a Fedora produced ISO image. And that's because that image is a read-only ISO 9660 file system. Hence my advice in related bug: https://bugzilla.redhat.com/show_bug.cgi?id=1883609#c30 In this case you can replace it by just copying a substitute grubx64.efi to the proper location on the USB stick... which might be EFI/BOOT, I'd have to poke it with a stick to find out. -- Chris Murphy _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org 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@lists.fedoraproject.org
