Windows users, installing a second copy of Windows XP

Windows users, installing a second copy of Windows XP in its own partition
can also be helpful as a way to experiment with a program or device driver that is not certified
to be compatible with Windows XP without possibly compromising a working system. After
you finish setting up the second, clean version of Windows XP, you’ll see an additional entry
on the startup menu that corresponds to your new installation. (The newly installed version
is the default menu choice; it runs automatically if 30 seconds pass and you don’t make a
choice.) Experiment with the program or driver and see how well it works. If, after testing
thoroughly, you’re satisfied that the program is safe to use, you can add it to the Windows XP
installation you use every day. If it causes problems, you can remove the program or driver.
