How can i boot from a USB on the HP Chromebook 11 G5?

[droppercomber]

I've recently gotten an HP Chromebook 11 G5 and am looking to boot software off a USB. However, I've been unsuccessful in all my attempts. I've tried the following (all of these were done after putting the computer in developer mode):

1. I tried going to press CTRL+L and CTRL+U as instructed in some sites, but every time the computer would beep and refresh the white recovery screen without doing anything else.

2. I then tried going into the terminal as root and type the following commands: "crossystem dev_boot_usb=1 dev_boot_legacy=1" or "crossystem dev_boot_usb=1 dev_boot_signed_only=0". Then i repreated step 1 but still the same thing happened.

Other solutions i found were either outdated or were not compatible with this chromebook.

Everything was done with a wireless internet connection.

My goal is to install some popular linux distro on my hardrive, as chrome OS does not fit my needs, and neither does the "crouton" solution.

How should i deasl with this?

thank you

Have you watched this YouTube video:   https://www.youtube.com/watch?v=UWXO61_v_xo

It talks about "developer" mode, and booting from USB.
