Ok, that should be easily fixable. It's of course wrong when there's no
boot device at all ;)

The only reason why i want to have this feature is because my Thinkpad
spents the boot wait delay (default 2.5s) waiting for the user to press
the F12 key, even though there's only one Boot device.

But if i insert a USB device, i want to have the menu - that's the
reason why i've added this.
