You cannot upgrade from XP directly to Windows 7. You must upgrade to Vista first, or perform a new installation.
...with Windows XP Professional already installed on your computer. Windows Vista cannot be installed without Windows XP Professional installed first on your computer, it's the same with Windows 7; Windows' latest operating system (OS).
It's one of the first Windows operating systems.
You have two choices. First one is to use virtual machines (VMWare is one of the best ones). Or you can make your system dual boot. For that you need to have at least two partitions large enough to hold Vista or Windows 7. First install Vista in the first partition, second, install Windows 7 as a new installation in another partition.
Install Win XP on the first hard drive, then install Vista from Xp and on question about "what kind of installation do you want to have?" Answer "separate" installation. When it asks you "which hard drive are you going to use?" Choose the second one. Vista will create a boot list automatically.

Just insert your Vista DVD and start installation from Windows Xp, choose new installation and choose that hard drive where to want to install Vista (your second hard drive). Vista will make all required jobs including boot screen to choose which OS to boot. Before you start, please, bakc up all your data from your hard drive(s).

Vista has DX 10 when WIndows XP doesnt. While Vista was suppose to be the upgrade to XP, it had a lot of problems during the first launch and it took awhile to fix everything. Vista is suppose to run faster, and use less resources on your system. But Vista failed and Microsoft then released Windows 7 as the replacement to Vista.
