Assuming you have the Intel provided UEFI fastboot firmware, I would
suggest using scripts/contrib/mkefidisk.sh rather than dd'ing the
hddimg. The hddimg is not in a format that is well supported by EFI.

mkefidisk.sh partitions the target device and creates a proper EFI
partition and a root partition.

You don't see GRUB over the serial port? Do you see the UEFI shell on
the serial port. Does the ttyUSB* device appear on your host machine?
Are you configured at 115200 8n1?

Try mkefidisk.sh and let us know the result.
