I’ll give you a general method. Two, in fact.
Choose one install to be “master”, meaning that this one will have grub on the MBR.
Alternatively, have a generic MBR, have a primary partition marked as bootable, and have grub
installed on that partition (which has to be the one holding /boot).
Now, for the second linux install, tell its installer to install grub to its root (or /boot if
separate), never to the mbr.
If available, this root (/) or /boot can be another spare primary partition, and marked bootable
instead of the previous one. This is optional, would make the second install the master one,
reversable any time.
Now, have the first grub point to the second grub (you will have to find the exact hd numbers for
yours, of course):
title Bombadil – (via configfile in /dev/sda1)
and the second grub point to the first one:
title Elessar x64 – (via configfile in /dev/sda3)
This will allow you to start the second grub menu from the first one.
If you are using two primary partition marking bootable one or another, then you can change that
mark this way:
title Bombadil – via chainload - changes active boot to /dev/sda1
title Elessar – via chainload - changes active boot to /dev/sda3
This system makes “permanent” the change, so that when you boot the computer you always get grub
number 1, or grub number 2, till you change it again by changing the bootable mark. This system can
be used for three installs - perhaps four if the extended partition can be used this way, I don’t know.
The advantage of these two systems is that each install manages completely its own grub without
interferences. It is really simple and easy to mantain. You can have as many linuxes as you like
(with the first one).
