Nice, thanks for your feedback!

Is it impossible to boot directly from the USB image on this machine?

I’m not familiar with GRUB’s EFI support.  Why do we need the ‘loader’
and ‘options’ lines instead of just one ‘linux’ line?

Should be provide a field in ‘grub-configuration’ that would allow one
to choose an EFI installation?  This sounds similar to special-case for
Libreboot that was recently proposed.

Thanks,
