1. Start with Windows 7
2. Download and Install Windows XP Mode with Virtual PC: http://www.microsoft.com/windows/virtual-pc/download.aspx
3. Type "Virtual PC" at the start menu.
4. Click the "Create virtual machine button" at the quirky folder that opens.
   
5. Make a new machine, and then right-click on it and pick "Settings" to set where the virtual machine should look to install an operating system.
