If I understand correctly, you have two different hard drives with two different operating systems (OS's) and you want a choice at start-up which one to choose.

The following is an example booting Fedora 11 and Windows 2000.

Please note that I have set the default to 10 seconds in order to select the OS I want.

Without making a choice Fedora, (default 0), would boot automatically after the 10 second countdown expires.

Windows would be default 1 in this example.

Also note that hiddenmenu has been commented out. 

This then provides a splash screen with the 2 "title" choices.

In Kubuntu you would edit the /boot/grub/menu.lst file to accomplish this.

title Fedora 11.x86_64)
   root (hd0,0)
   kernel /vmlinuz- ro root=/dev/VolGroup00/LogVol00 rhgb quiet vga=0x318
   initrd /initrd-
title Windows 2000 Pro
   map (hd0,0) (hd1,0)
   map (hd1,0) (hd0,0)
   rootnoverify (hd1,0)
   chainloader +1
