It may be one of the TPM related patches for GRUB. I suggest filing a bug, as during the entire pre-release testing of beta no one ran into this and the more information that's collected about the problem the better off Fedora is for final release. Include in the bug cc: mjg59@xxxxxxxxxxxxx More info on TPMs and measured boot. http://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx/message/LTZW5RA3VAYGS7GFIXNYUU3GJBNLPGPH After that, you can probably fix this by booting any media you have and putting the new system in a chroot: mount <devrootfs> /mnt mount <devboot> /mnt/boot mount -B /sys /mnt/sys mount -B /dev /mnt/dev mount -B /proc /mnt/proc chroot /mnt curl -Os https://kojipkgs.fedoraproject.org//packages/grub2/2.02/0.25.fc23/x86_64/grub2-2.02-0.25.fc23.x86_64.rpm & curl -Os https://kojipkgs.fedoraproject.org//packages/grub2/2.02/0.25.fc23/x86_64/grub2-tools-2.02-0.25.fc23.x86_64.rpm & curl -Os https://kojipkgs.fedoraproject.org//packages/grub2/2.02/0.25.fc23/x86_64/grub2-efi-2.02-0.25.fc23.x86_64.rpm & dnf downgrade *rpm grub2-install /dev/sdX exit reboot Seems like it ought to be easier but that's what I'm thinking off off hand. -- Chris Murphy -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: http://lists.fedoraproject.org/admin/lists/test@xxxxxxxxxxxxxxxxxxxxxxx
