Multiboot Specification

Imagine you have a lot of toys to play with and you can only play with one at a time. Multiboot is like having a special toy box that can hold all of your toys and allows you to easily choose which toy you want to play with.

When you turn on your computer, it needs to know which operating system it should start running, like Windows, macOS or Linux. Multiboot is a set of rules that tell your computer how to identify and boot different operating systems that are installed on the same hard drive or a different one.

Multiboot also allows you to customize the boot process by giving you the option to choose which operating system you want to start, or to load special programs that are designed to help you troubleshoot and fix any issues.

Overall, multiboot specification is like a toy box that helps your computer quickly and easily start the operating system you want to use, and it gives you flexibility to choose which one you want to play with.
