Cleaning up boot loader

[Dist]

Does anyone know how I got about removing entries in the boot loader that comes with Ubuntu (I think it is called GRUB)? The problem is that as well as listing the latest version of ubuntu and its recovery mode, it also lists 3 previous versions along with their recovery mode. Also, as well as my XP install, for some reason it lists NT there as well.

I am not sure if the old versions are usable, or if the NT one is usable, but none of them are needed so I would like to know how I would go about removing them from the boot loader.

I searched the package manager for linux-image, and it is showing 2.6.28-13 and 2.6.28-14 being installed, but when i search for 28-11 it is not even listed in the package manager (either as installed or not installed).

As for the extra MS OS, I ran it just incase and it turns out it was the hidden thinkvantage recovery partition on my thinkpad, so i renamed it in grub rather than remove it, as who knows when it may come in handy.
