I'm pretty sure that was not OP's intent, i.e., none of Grub at all in MBR.
Yes, no grub in mbr - unless installer insists.

FWIW, this done just now:
# gdisk /dev/sda
GPT fdisk (gdisk) version 0.8.10
Partition table scan:
    MBR: protective
    BSD: not present
    APM: not present
    GPT: present
Found valid GPT with protective MBR; using GPT.
Command (? for help): b
Enter backup filename to save: mbrforgpt
The operation has completed successfully.
Command (? for help): q
  I don't see anything above to indicate a boot flag has been set anywhere. That
HP might have firmware that insists one exists.

# ls -l mbr*
-rw-r--r-- 1 root root 17920 Dec  4 05:47 mbrforgpt
# mc -v mbrforgpt
The above shows 0x55AA at +0x1FE (Boot signature [1]).
  That proves a partition table exists, not whether there is requisite code in
the 446 bytes preceding the table.

Also, the search for 'ERROR:' is not found in the entire 17920 bytes of
file mbrforgpt.
  'ERROR: ' you are encountering is coming from the BIOS/firmware, not anything
on the disk.

Apparently, all is in readiness. It's simply that this PC is not loading
the mbr or anything else from sda. Any other opinions?
  <all, or you wouldn't be getting the ERROR: message. :-p

True, that! :-) There's that business about the pesky bit again. One in 1T.
