OK so some kind of regression in GRUB, but also a firmware bug because otherwise many other people would run into this. It's GRUB 2.02 in Fedora 31 and GRUB 2.04 in Fedora 32. So it could be an upstream bug. Where I'd start is making a livecd-iso-to-disk based USB stick, from the Fedora 32 ISO that you already know fails, and make sure it still fails when created this way. If it doesn't, then it's probably not GRUB it's something else about the image. But assuming it fails, you now have an easily modifiable USB stick, it's read-writable, so you can just copy each test grubx64.efi binary onto the stick. You could start with this, pretty sure it'll fail too. So just extract the grubx64.efi from grub2-efi-x64-2.04-1.fc32.x86_64.rpm and replace the one on the USB stick. https://koji.fedoraproject.org/koji/buildinfo?buildID=1356278 -- 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
