Hi Liam and thanks for this trick but... if I get it correctly, this
method is based on running virtualbox in windows and executing those
commands EVERY time you want to boot Linux, isn't it? If so, it is not
applicable in my case. Eventually, the laptop must boot directly into
Linux by itself, because it will not be used by me, but by kids, or
teachers without any sysadmin experience at all, on any OS.

Or am I missing something?
