HD Install :: Too many options in LILO...

I've dual-booted DSL and Windows XP.

And the boot-menu is there successfully.

But in the bootmenu, I see Linux, WinNT hda1, WinNT hda2, WinNT hda3.............

There are too much extra "operating systems" there. I have only two which is Linux and WinXP.

So how to remove these extra options until two are shown only?

BTW, I used LILO as a bootloader...
