Public bug reported:
I don't have any ideas now. My 1 Tb must be too full. I deleted old
directories from the EFI directory, so the active ones are Win10 and
Fedora. I'll try 'grub-install /dev/sda' from a shell and look for more
information.

Public bug reported:
My efi boot directory probably is too full. I will boot live Ubuntu,
cleanup my efi directory and try again.
