There can be multiple operating systems on a computer. A computer having more than one OS is known as a dual boot system. In a dual boot computer, the hardware usage is shared by two different operating systems. There are some advantages and disadvantages associated with the dual booting of computers.

Advantages associated with the dual-boot operating systems are as follows:

Multiple operating systems can be operated on a single computer with the help of an option provided in the boot menu of system. If one of the operating systems was corrupted, you can work with other operating system. In this way, the dual booting of the system offers a smoother work environment. If any software or application is not working with an operating system, you can check it with another one.

Following are the disadvantages associated with the dual booting of operating systems:

The main disadvantage of dual booting is the degraded performance of a computer as the hardware and memory usage is shared with two OS. Another bug in dual booting is the clash between different applications. The clash between applications uses system memory and thereby the performance of system may be affected.
