Public bug reported:
Ubuntu 15.04
With the --removable switch, grub-install will now correctly install
grubx64.efi as the default bootloader
in the EFI partition's /EFI/Boot/bootx64.efi file, but with the addition of
--uefi-secure-boot, it still
uses grubx64.efi as bootx64.efi instead of shimx64.efi. The use of both
--removable and --uefi-secure-boot
should result in shimx64.efi copied to the /EFI/Boot/bootx64.efi file, and
grubx64.efi just copied to the
/EFI/Boot directory.
Since the shimx64 as bootx64.efi will work with secure boot enabled or
disabled, the easiest solution would be to just use it every time the
--removable is used.
grubx64.efi will not successfully boot a UEFI machine with secure boot
enabled.
