Well the autopsy is that the advice to re-install grub wasn't appropriate for UEFI computers, and actually makes the problem worse on UEFI computers with Secure Boot enabled. By using grub2-install, a custom grubx64.efi (core.img) was created and replaced the signed one making what was actually a booting system, not bootable. To replace the signed one, you need to boot the DVD with the rescue a system option found in the troubleshooting menu. Accept the default options in the menus. cp /run/install/repo/EFI/BOOT/grubx64.efi /mnt/sysimage/boot/efi/EFI/fedora/ chroot /mnt/sysimage grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg exit reboot See the other email I posted for what information you need to supply to fix your original problem.
