Dual Boot

Grub with ubuntu linux and windows vista

Dual boot or Multi boot is the act of installing multiple operating systems on a computer, and being able to choose which one to boot when switching on the computer power. The program which makes multi booting possible is called a boot loader.It is useful in many situations, such as those where several pieces of software require different operating systems and cannot be run on a single system. A multi boot configuration will allow a user to use all of this software on one computer.

Another reason for setting up a multi boot system can be that one wants to investigate or test a new operating system without switching completely. Multi booting allows one to get to know the new system, configure all applications needed and migrate data before making the final step and removing the old operating system. This is often accomplished by using a boot loader that can boot more than one operating system, such as NTLDR, LILO, or GRUB.

Multi booting can also aid software developers where multiple operating systems are required for development or testing purposes. Having these systems on one machine can greatly reduce hardware costs.
