Yes, I did that multiple times. I think it was attempting to open x-wayland as root that failed for me. Though running /mnt/guest/start_desktop.sh 1 didn't work for me either - I have to run it with a '0' at the end instead of the '1' for the desktop to start.

Edit: I just realised what the 1 or 0 represent, and either work for me.
