Can't boot Windows Vista after installing Ubuntu

I'm very new to Ubuntu, and have come to this point that I can't boot back to my Windows Vista anymore.

I thought that I would get some kind of dual boot in the beginning when booting my computer, but this doesn't seem too happen and I don't have the slightest idea on how to fix this. I was looking for help here at askubuntu, but I couldn't seem to find anything. I'm too new with this software.

I'll need hints and tips on how to fix this

Thanks for your time folks!

When booting back up, you should see the GRUB menu. In this menu, you should see a list of the operating systems you can boot up. Arrow down to Windows Vista and hit enter. Then it should boot Windows Vista. If you don't see the GRUB menu or you don't see Windows Vista listed, then you probably accidentally erased Vista while installing Ubuntu.
