The XP Pro CD you have from Dell, is it the same one that is installed on
your wife's computer. If so and you attempt to install it on your Dell you
will violate the EULA for the product.
Sure the CD said "not to use on" and that it did not say "for use on a new
computer"? If it said the later it is an OEM version and can only be
installed and used on the first computer it is ever installed on according
to the EULA.
Make sure that Dell has all the drivers for XP as they are in all
probability different than the drivers for Vista.
If this is a retail purchased XP Pro and it's activation key has not been
used on any other computer actively being used and you can fill all the
proper drivers for XP for your system boot with the XP Pro CD, delete any
partitions and install XP Pro using the XP drivers you have already
downloaded and put on a CD. (Make sure you have all the recovery
information, disks, etc to be able to return your system to Vista if you
ever need to.)
