Yes, I have a small partition on both disks around 2-4MiB. That didn't 
help. I did it using parted, something like:

# parted /dev/sda
(parted) unit MB
(parted) mklabel gpt
(parted) mkpart primary 0 2

From Gparted it was visible as "bios_grub" labelled partition, if I 
recall correctly. I could check for sure...
But, after all, I manage to install grub manually, so it should be 
fine... I believe...
