All right so it appears it was the right choice because now when I run the crossystem command to boot from USB, it didn't just sit there and wait for me to sudo reboot it. It gave me a long list of other commands, of which I had not seen before until now. I still proceeded to reboot as is, tried CTRL+L, got beeped at so that was no where.
Logged in as Guest, ran a browser tab, got into the terminal, then shell then ran the command there. No go.
Did this again in Developer Mode through the boot screen and same idea.
