Does not work on HP Chromebook 11 G2

[sleepy9090]

Everything runs without error. On reboot after pressing CTRL-U, the screen is lit up for a few seconds then goes to a black screen. I can hear that the chromebook is still on but nothing is happening. I have to hold down power for x seconds, then tap power again and the chromebook turns back on back to the chrome screen.

Tested with 2 different usb drives, sandisk cruzer glide 16gb and a sony 4gb.

I also manually tested using the instructions here:

but I had the same results, so it is possible it just doesn't work on HP 11 G2.
