Yep it looks full of superfluous boot entries. There were some combination of firmware and shim.efi that caused this problem. You can delete Boot0019 through Boot0129. Use either 'efibootmgr -b XXXX -B' or rm from efivars/ but I wouldn't try deleting 0000 through 0018. Basically don't delete anything you don't know exactly what it does. But any boot entry that's pointing to shim.efi can be removed. Next make sure you have a current shim.efi. I can't tell you if the Fedora shim package overwrites EFI/BOOT/ so I would just remove whatever is in there, and then 'dnf reinstall shim grub2-efi' and that'll repopulate both EFI/BOOT/ and EFI/fedora/ with the right things. While it shouldn't matter, you could top it all off with 'grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg' to get it back to a stock state. # sha256sum /boot/efi/EFI/BOOT/BOOTX64.EFI 475552c7476ad45e42344eee8b30d44c264d200ac2468428aa86fc8795fb6e34 /boot/efi/EFI/BOOT/BOOTX64.EFI What you should have now at reboot is a one time fallback to BOOT/BOOTX64.EFI which won't find a proper boot entry, and it'll create one and one only. And you won't even notice that happen probably. So reboot a few times and check 'efibootmgr -v' to see if you start getting accumulating boot entries again or not. And if you haven't done it already make certain the firmware is up to date. -- Chris Murphy -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx http://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx
