What I would like to clearly understand is:-
a. As I finish 'looking at' a distro, can I just eliminate it from the

Your favourite text editor is (probably) fine for making changes to
/boot/grub/menu.lst - I most frequenly use vim.
Debian has a tool for automatically updating grub's menu, and it works
out what to put in there by inspecting /boot. It will play with stuff
between these two markers:
### BEGIN AUTOMAGIC KERNELS LIST
### END DEBIAN AUTOMAGIC KERNELS LIST
I assume you have grub nicely placed in the master boot record for your
the Debian tool will not know what other kernels and such are around in
your other distros: what if you wrote your own filesystem and called it
What I recommend is that, for each other OS, you install its boot loader
in its partition: hda1, hda2 hda6, hda15 etc in Linux terms.
For each such partition, in grub have an entry modelled on this:
title Red Hat Linux 7.0
It does not matter whether it's before the above section or after it.
This stanza loads LILO, but it could just as well be loading DOS or Darwin.
If you've read closely, you will have noticed it's actually loading the
MBR of the second drive.
With this setup I can diddle away with RHL as much as I like, install
kernels, remove kernels, reformat the drive and install OS/2: whatever I
do, grub on the first drive is unaffected, and whatever is on the second
drive will get booted when I choose the RHL 7.0 entry.
It would be exactly similar if I were playing with other paritions on
the first drive: I'd have
