Saikee is pretty close to the undisputed master of such things. Maybe he'll spot this post and provide a more recent link.
PCLinuxOS and kubuntu may provide extra challenge. If kubuntu follows ubuntu practice, the alternative install disk is needed to easily place grub in root. PClinux afaik uses lilo rather than grub.
Check this link if you want to know how to use grub with PClinuxOS instead of lilo.
Then you could chainload adding the new install to whatever grub is installed to the Mbr of hda.
If you want PClinuxOS installed on hda6 for example you would use grub on the PClinuxOS installation, installing grub to root on the PClinuxOS install then just add this to your existing grub(the one on the Mbr of hda)
title PClinuxOS at hda6
See the link at the bottom of this post to find out to load 145 operating systems on one computer and set it all up using grub. Interesting work.
I use this method and can chainload as many operating systems as I can ever use. I have nine systems installed. All are chainloaded except the one that has grub installed to the Mbr of hda.
The grub that is installed to the Mbr of hda is the only one that you want to edit. All of the chainloaded ones have grub installed to root.
A big advantage of having grub installed to root on hda6 is that when I install another operating system to that partition I don't have to re-edit the main grub at all. I would only edit it where the title is to show what's really installed there, and you don't even need to do that. It will boot if you install another linux to hda6 and install grub to root on that install.
Here is a post of mine at another forum explaining about triple booting and grub editing. The link has three links so hope it is what you are looking for.
Look for my post on the thread.
