First of all, I know there are other threads from users who've had the same problem. I did try reading those but I couldn't really make any progress. I have run the boot info script and I got the following output.

I'm not very proficient with partitioning, although I do have a basic understanding of how this works. I also don't happen to have an XP recovery CD.. Is there anything I can do?
Thanks.

You have installed grub2 to the XP partition during the upgrade. You need to perform this fix on /dev/sda1, so that's partition #1 on disk /dev/sda:
http://sourceforge.net/apps/mediawiki/bootinfoscript/index.php?title=Boot_Problems:Boot_Sector

It should be OK after that.
