2. Click on Disk Management
3. Right click on the drive you wan to split and hit shrink.
4. With the extra space format the space into a drive.
5. Place the windows XP cd in the drive and install XP (or your desired OS) to that drive.

There is one last step. There is a possibility that after installing xp or linux that your Vista will not be in the boot manager.

6. Pop in the windows vista cd, boot the pc off the cd, After the cd boots up click on the fix button. The fix utility will take care of the system files that enable you to choose which os to load when the pc is turned on.
