-:: Recent versions of grub may fail to boot with secure boot enabled. The
-   message will look like this:

-   Handle installation to UEFI with care and be prepared!

+:: Grub does no longer support side-loading modules when secure boot is
+   enabled. Thus booting will fail, unless you have an efi executable
+   'grubx64.efi' with bundled modules.
