On getting to the boot menu: if I reboot with no usb stick inserted, I can get into the firmware options menu via "esc". But if I have either a Libreelec or Ubuntu usb stick inserted when I reboot, "esc" does not workand the Chromebox goes straight to booting from the SSD. So having flashed to the new firmware, I can now no longer boot from USB.
