Hmmm, I don't recall the screen of the Kubuntu installer now, however, you should be able to force the installer to use on hda4 (if that is the correct name) without touching the other partitions.
If your happy to reinstall XP from image, then, I would (note. i do silly things, this is not necessarily recommended!) boot the deb/kubun install disk, and wipe the HD of all partitions (again, ONLY if EVERYTHING is backed up safely) then install Linux, but only to 1/2 of the HD (or whatever size you like) install GRUB, and also make a GRUB Boot Floppy, as when u install XP again, if you do, it will wipe out the GRUB.
So yeah, thats what I would do as I'm a bit of a meddler. IF your not quite mad enough for that, the Live CD environment of a number of Linux Distros is a great way to begin learning.
The standard Ubuntu install process seemed straightforward to me but it assumes a lot and I think the way it will only install GRUB and only as the MBR has caused a lot of grief.
The "Alternate" install disk is supposed to be better at getting it running on low spec systems but I haven't tried it myself.
