Install grub to partition

I would like to install Calculate CLDG 10.9 beta 1 to a partiton. I would also like to install grub to the partition and not to the MBR. Can I do this using cl-install with the appropriate parameters? If so what would they be? There does not seem to be an option to install grub to a partition in cl-install-gui.

Thanks in advance.

Sync portages and update calculate-install package:

emerge calculate-install

and use cl-install with --mbr=off option.

Thanks for your reply. I will give it a try. I did some along the lines with --set-mbr=off but cl-install did not like the parameter.

I tried it but the 10.9 beta installer does not recognize the --mbr=off option nor does it recognize --set-mbr=off as described in the documentation.
