No, it isn't.

It sounds like your BIOS implements Fast Boot
<http://mjg59.dreamwidth.org/24869.html>, but then I don't understand
how you booted the installer originally.

According to <http://superuser.com/a/535953>, you can enter BIOS setup
from grub-efi by going to the command line and running 'fwsetup'.  From
here you may be able to select a new boot device or disable Fast Boot.
