[GoFigureItOut]

I'm trying to triple boot my laptop for the first time. I started off with just Windows 7, and I installed Ubuntu 11.04. All went well from the dual-booting aspect. After installing Windows XP, I had to use Boot Repair, so grub will be the default boot loader. The only way I can boot into XP is selecting Windows 7 from the grub menu, then choose XP from Windows 7 boot manager. How can I add XP to Ubuntu boot menu? I've tried editing /etc/default/grub and using os-prober to no avail. Basically, I want to be able to use XP without going through Windows 7. I read some where that you can manually add entries, but I have no idea as to where. It goes something like this:

title Windows XP
root (hd0,1)
makeactive
chainloader +1

Any help is greatly appreciated!
