I have a extra OS listed in my grub menu. I'm dual booting Ubuntu 10.04 and Windows 7. I am able to boot into both Ubuntu and Windows. 30_os-prober has two menu entries for Windows though. The first one is Windows 7 (loader) (on /dev/sda1) and the second is Windows Vista (loader) (on /dev/sda2). My laptop came with Windows 7 and had 4 primary partitions (System, Windows, Recovery, HP_TOOLS). After making my recovery disks I removed the Recovery partition and shrunk the Windows partition to make space for Ubuntu. So Windows 7 (loader) (on /dev/sda1) is the System partition which I select to boot Windows. Windows Vista (loader) (on /dev/sda2) is where my Windows 7 is installed.
Here is output from Boot Info Script (http://sourceforge.net/projects/bootinfoscript/):
