Why have two operating systems ?

A recent post:
I am looking for information that will show me how to build multiple
installations (2 minimum) of Windows 2000 Professional on the same physical
disk (multi-boot). I need the option to choose which installation I will
boot
from when I start the CPU.
-------------------------------------
Can someone explain why
some people want 2 installations of the
same OS.

One reason might be to have one OS as the working system,
the other as the experimental system. However, unless this
is a laptop, having two exchangeable disks would be a
more robust solution.

Can you suggest how the experimental disk might be returned to it's
initail state, or to the same state as the reference disk?

By a cloning or imaging process.
