OK all you nit picking twits. Given the nature of the question one need not
be so specific in a response. Given that the man has an Apple and wants to
install Windows - in general - not possible in the manner suggested by The
Undertaker.
To be complete with the answer, Microsoft Windows XP as published for Intel
[and Intel Compatible products, although one generally does not specifically
state AMD as anyone with one day's experience in computers knows of this]
will not install or operate in the Apple Computer.
However, it is possible to Emulate Windows on a Mac with OSX: 'Virtual PC 7'
works by emulating a Pentium-based Windows machine on your Mac. When you
launch Virtual PC, the Windows OS appears inside a window on your Mac
desktop.
You can switch back and forth between your Mac OS and Windows as easily as
you go between any two windows on your Mac desktop. Using Virtual PC, you can
copy and paste text and graphics between Mac and Windows, and drag files and
folders from one OS to the other.

This goes more to the point of solving The Undertaker's needs.
