Tried to dual boot 6.06 and vista. Ubuntu works, Vista does not show up on grub.

I had windows Vista already installed my my laptop. I installed Ubuntu 6.06 (thought i grabbed the 7.04 cd but didn't realize it was the old cd until Ubuntu was already installed). Now when i start up my computer I do not get an option to choose between vista and ubuntu. I think my problem is similar to the one here:

I didnt have any problems when installing. I know i didn't write over my vista partition. I had 93gb for vista, 10gb for linux, and 8 gb or something for my HP recovery partition that came with my laptop. Its a 120 gb harddrive. I would really like to get vista and ununtu working without having to reinstall windows. Help is appreciated. Thanks!
