Right, I wanted the boot loader of sda to start the boot loader of sdb so I would not have to manually update the stanzas in the fedora grub.conf file. > > I think though using the chainloader path makes the updating the > mandriva kernel more transparent and cleaner.

When I choose that option the grub of mandriva loads and I can see any mandriva supplied updates. > The way you are doing it you should leave the softlink > for /etc/grub.conf for mandriva pointing at its /boot/grub.conf on sdb. In my OP, I thought it would trivial to make the boot loader installed on the mbr of /dev/sda to the mbr of a second drive, not so though. Unless someone else has an idea I am thinking that it cannot be done. -- John Registered Linux User 263680, get counted at http://counter.li.org
