Dual Booting:
Allows two or more operating systems to exist in a single hard disk. Each operating system is installed in a different partition. When you start the computer you will have a menu of choice between which operating system to load with. Dual booting is supported by all the Windows operating systems.
You need to take certain measures before installing the dual operating systems. You must also consider compatibility issues.
