Yes, that's what I said, or thought I said. This will install grub to 
where you want (not the OS grub.cfg though) *as well* as leaving it at 
the /boot/grub/ of the OS too AND setting the <where you want> grub.cfg 
to mbr, NOT the OS grub.cfg.

That is...
o <where you want> grub.cfg is set to mbr
o OS grub.cfg is NOT set to mbr
o OS /boot/grub and OS /boot/grub/grub.cfg
   will remain unchanged at OS partition
o updates the <where you want> grub with OS grub version
   but NOT the <where you want>grub.cfg with OS grub.cfg

I've learnt to happily accept the warning sign  :)
