The nv-u-boot on KERN-B partition can boot from usb but I've not tested. Might try that durring flock.

twice, with a SD card and an external USB 3.0 hard disk. To cut a
long story short, SD card works fine, but USB hard disk just beeps and
fails to boot.
The USB hard disk is brand new, from a reputable supplier, and works
on other machines. It even works fine on the Chromebook once it has
been booted into ChromeOS. Here is the partition table:

I can't find any documentation that says that the Chromebook
definitively cannot boot from USB 3.0 or from external HDDs. (Also it
doesn't work when the same disk is plugged into the USB 2 port).
Any ideas? I'd really like to eliminate dodgy flash cards from
my life.
Rich.
