This happens because while installing Windows XP, you have overwritten boot sector at MBR (master boot record).
All you'll have to do is boot via Ubuntu CD/DVD and there will be some option like repair or rescue etc. It will guide you regarding how to install bootloader. I've used Ubuntu very rarely, so I don't have any idea if it does support it.
Otherwise, you can try some other live CD (e.g. Puppy Linux) as well (because bootloader is just a reference to actual partition) and try installing GRUB or LILO with (at least) 2 entries - one for Windows and 1 for Linux.

but how to install GRUB and what is grub?
GRUB (GRand Unified Bootloader) is a bootloader (a piece of code which sits at boot sector of bootable disk and is responsible for initiating boot process).
As you are not aware of it, I would not suggest to install bootloader from command line (because if you run straight-forward command, you'll end up in another mess - bootloader only pointing to Linux etc.).
Best approach would be what I suggested in previous mail - rescue/repair the system using live CD.
Well, I'm not sure how to fix this via Ubuntu live CD. It might be somewhere during install (say, instead of a clean install, it would ask something like if you want to repair, or make a new install etc.)
But, before even touching the install option,
1) Boot using 'Try Ubuntu'.
2) Take backup of everything on an external drive. You never know what goes wrong, and when.
3) Next time onwards, create a separate /home partition (if you haven't already). That way, even if you reinstall on / partition, your data (/home) would be safe.
