I used to use Crouton to run Ubuntu on my Acer C720. It worked well but other users kept writing over the boot info that permits access to the Crouton install.
Is it possible to configure a Chromebook to boot into something like Gallium OS from a USB stick, without making modifications to the Chromebook hardware? I now have an Acer R11.
- change the firmware to permit the USB alternative OS booting that I wanted
- remove the obnoxious white warning screen that occurs after 'developer' mode is activated (and replace it with a black screen with small white lettering)

- change the bootup choice delay from 30s down to 1s
- change the default boot device from the internal SSD/eMMC to the USB external device instead (I prefer that ChromeOS remain the default, but I like the 1s boot delay)
