I did it, but nothing...the light of the key flashes two time and stops and nothing appears on the screen. I have also tried update grub on my hd to include the item linked to the usb and as soos as I click on it I can see only a magenta screen. Is there a way to debug what is happening. In which filesystem grub is written on the key (ext2?)
