Triple-boot? -- XP Pro/ubuntu [or kubuntu]/Mandriva

[Chuck Mattsen]

I currently have a dual-boot XP Pro/Mandriva cooker setup, but I want to 
install Ubuntu (or Kubuntu) while leaving both XP and Mdv intact.  I've 
searched around, and see scattered references here and there to 
setting up a triple-boot setup, but nothing [yet] that's dumbed-down enough 
for me, as I tend to freak out when it comes to the lower-level stuff like 
partitioning, file systems, manually modifying lilo, etc.

Anyone have a pointer/URL to a decent, basic walk-through for setting up a 
triple-boot? (Keeping in mind that my skills and knowledge are rather limited 
and basic.)  FWIW, if it helps point me in the right direction, my current 
disk usage/setup is:
        hda1    NTFS            XP Pro          14 GB
        empty   unformatted     empty           9.7 GB
        hda5    ext3            / (Mandriva)    5.8 GB
        hda6    swap            swap (")        499 MB
        hda7    ext3            /home (")       6.5 GB

Ultimately, I want to run Ubuntu (or Kubuntu), but need the others intact 
and operational for some time to come.  I'd be significantly less paranoid about the whole process if I had a second drive, or second machine, but I currently don't and there isn't one in the cards for the foreseeable near future.

TIA
