I need to add XP to my Vista
It is not possible to "add XP to [your] Vista ." Windows XP and
Windows Vista are each operating systems. They are separate from each
other, and neither can be "added" to the other.
Perhaps what you want is to have both operating systems installed on
your computer, which presently has Vista installed on it. Is that
correct?
so I am able to work from home.
Why do you think you need XP to do this? What application(s) do you
need to run at home, and what makes you think that it (or they) won't
run under Vista. With few exceptions, anything that runs under XP
should also run under Vista.
If you actually need to do this (and I suspect that you don't), and if
you want a dual-boot scenario, with both operating systems on your
computer, so you can choose between them, yes, it's possible to do
this, but what you want to do is the hard way to accomplish it. It's
considerably easier to add a newer operating than an older one.
Another choice is to run Windows XP within a virtual PC environment.
One more point: I don't mean to be insulting, but the phrasing of your
question suggests that you are a relative beginner at using
computers. If that's the case, I would suggest that you get this done
by a professional, rather than trying to do it yourself. The risk of
screwing up everything is otherwise great.
