FIxing boot loader after installing windows xp

[kimolias]

I have a Sony Vaio VGN-NR21S laptop and it came (unfortunately) pre-installed with Windows Vista.

I successfully installed Ubuntu 8.04 (Hardy Heron) using this amazing how to:
http://apcmag.com/how_to_dualboot_vista_with_linux_vista_installed_f irst.htm?page=1

Then I found this other great how to on downgrading my Vista to XP (which, to my great luck, he had the same laptop model):
http://www.spydro.be/tutorials/downgrade-your-laptop-to-xp/

So now my hard disk has four partitions:
40GB - Windows XP
165GB - FAT32 Data
30GB - Ununtu
SomeMB - Linux SWAP

But since I installed Windows XP last, the bootloader from the first how to doesn't work, thus, I'm incapable of booting into Ubuntu.

Can anyway help?
Thank you for your time,
Panagiotis

Anyway, thank you very much for your help and sorry for your time ;)
