How does the Ubuntu system modify the default boot system? It's really simple! The code is as follows:

sudo cp/boot/grub/menu.lst/boot/grub/menu.lst_backup
sudo gedit/boot/grub/menu.lst

Find the default 0 and change the 0 to the location of your other system, located at item X, which is modified to X-1 (starting from 0).
