After reading this again, did this:

I know this needs to be followed by more steps... the reference refers 
to Syslinux but we're using GRUB. It says:

2. Next, mount the partition somewhere, say in /mnt/data
3. Use [GRUB2] to install the boot loader, pretending that it is a 
regular partition:
4. Copy [ ? ] which is capable of booting GPT partition to the disk's MBR.

What is needed to fill the two [...]?

The mbr's first 446 bytes are non-empty, but possibly incompatible with 
bios.
