I think he's mistaken and what you've specified below is correct.
And my Bootmanager already DOES point to the drive with the Linux on it
(/dev/hdb in Linux talk) & can even point to the /boot partition
(/dev/hdb1) - -
Problem is that Linux does *not* boot.

From what I've found in the GRUB documents the Linux OS requires a special
Bootmanager to boot, it requires the Bootmanager itself to point to s file
location within a MS-Dos partition it calls "/boot"
- - other systems generally just use a boot-strap at the very start of the
drive or a MS style Dos-partition.
My problem is that this anaconda installation routine does not allow one to
"update" the installation drives own MBR unless it is the primary drive on
the system.

So can you tell me how do I mannually update the second drives MBR so that
it can boot the Linux OS that's installed on it?
