I do not think XP even had its own partitioning tool. Newer Windows does and we normally suggest you use it with newer NTFS partitions. I use gparted and think I used it back in XP days, but part of reason for suggesting Windows partitioning tools is that is any issue with the NTFS partition and gparted does not work, user blames Linux, not the real Windows issue.
BIOS boot on one drive has several things you need to know. You only have one MBR (per drive). So only one boot loader can be installed. Windows will not boot Ubuntu, but grub boot loader will boot working Windows. Linux tools cannot fix most Windows issues, so if Windows needs fixes, grub probably will not boot it and you need a Windows repair disk.
Or you need both Windows repair flash drive (if system boots from flash drive) and your Ubuntu installer to make possible repairs. And you must have good backups of both systems.
With an old BIOS only system a lighter weight flavor is probably better. Ubuntu not really designed for DVD install, and does not fit anymore. Latest Ubuntu is full featured and intended for newer systems probably within latest 10 years unless old system very highly configured. UEFI has been standard since 2012.
Even is XP is 32 bit, you may have 64 bit system. I used 32 bit Ubuntu on my XP desktop system and upgraded every 6 months. Had to do new install to convert to 64 bit Ubuntu in 2009. Only done new installs since then and use LTS versions as main working install.

Acouple of years ago, my new Dell laptop died & had to go back to Dell for repair. I needed laptop and pulled out my 2006 XP Dell. I had last installed Ubuntu in 2012. New Ubuntu would not install, server did install & I was able to add lightweight Fallback gui. But Kubuntu installed & was functional but very slow. Then I used my external SSD with full install of Kubuntu and while not speedy system very functional.
Or I suggest a full install on an external SSD, if system can boot from USB. I make my own by buying a $25 USB to M.2 adapter and SSD/NVMe drive.
