Things I've tried:When I hit enter with the first or second line selected, the screen goes dark and stays dark.
When I hit 'e' I see a screen with a similar box with 15 lines of what looks like config or code. If I hit f10 from that screen, the screen goes dark and stays dark.
When I hit 'c' a command line, I get a "grub>" command line following some instructions starting "Minimal BASH-like line editing is supported..."
