Sorry for the hard to understand title but it's difficult to describe in one sentence.
What I'd like to do is install Windows and several different versions of Linux on the same system. After everything is installed, I'd like to switch between operating systems from inside the operation systems.
I'm inside Windows but I want to reboot into Ubuntu 9.04. I need to run a command to update the boot manager so it knows to boot into Ubuntu 9.04.
I do not want to walk to the physical box to make a menu selection.
EDIT: I'd like to be able to switch between Windows 7 and Ubuntu (9.04, 10.04, and 10.10)
