I am not sure that I understand.
After this, you will need some other boot manager in your MBR,
something that can chainload the copy of GRUB in your Ubuntu root
partition. This setup alone will not be able to boot your computer.
It is a way of confining Ubuntu's GRUB within Ubuntu. You will need
some other bootloader, such as the FreeBSD one perhaps, or the Windows
one if you use Windows.
