If Vista has been installed on a partition which takes up 100% of the hard drive, you need to repartition your drive to make some space for XP. In Windows Vista, right click My Computer and select Manage. Expand Storage and select Disk Management. Right click on the drive that’s taking 100% of the hard drive space, and select Shrink Volume. Boot up computer with Windows XP CD and install it as normal on the new partition that you’ve created. Once XP is installed, boot up computer with Vista DVD. When you get the screen that says “Install Now“, at the bottom you’ll see “Repair your computer“. - Problem after installing Windows XP after Vista, you won’t be able to boot into Vista with Windows XP Boot Loader.
