When I try those commands I get error messages (see below). I just remembered something that might be related to this bug. A few months ago I followed a guide to fix a boot error (the computer would not boot into ubuntu without live DVD). I was able to fix the boot problem, but maybe its solution is causing this bug? Here is the guide I followed: http://heeris.id.au/2014/ubuntu-plus-mac-pure-efi-boot/#fixing-efi
