If it was me i would download another Linux (Debian or Xubuntu) and install that where SUSE was to reside, it should work out ok and get your XP going WITHOUT having to reinstall.
you wouls need 3-4 partitions total.
one for Xp
two or preferably three for linux
I would go with the four of them as primary partitions (4 is maximum then, no adding later)
C: for XP, Windows wants this first on the disk for some reason. i personally made it 10G over updated XP install and added 1G of other stuff but that is me, you may have other wishes.
/ root partition say 5-8G (plenty room to play)
/home whatever is left when 2x ram is made into Swap partition.

why a separate / home? so that if i reinstall or add another Linux i can still use my / home untouched where all my personal files... are.
/ home in other words is about like having a separate documents and settings folder in Windows but as on its own partition easier to keep settings, wallpapers, mail... when formatting
