Step-by-step explanation:
A dual-boot option allows a user to run two or more operating systems on a single computer system. It is a useful feature for individuals who may need to switch between different operating systems for various purposes, such as compatibility with specific software or experimenting with different systems.
For example, a user might have a dual-boot setup with both Windows and Linux operating systems. They can choose which one to boot into at startup and have access to the full functionality of each system.
Setting up a dual-boot system typically involves partitioning the computer's hard drive and installing each operating system on a separate partition. The user can then select the desired operating system when the computer starts up.
