    Both Etcher and Rufus are fairly simple to use.

    • Download the iso file of the operating system.

    Overall, we can use an ISO file in three ways. We could access the contents of the iso file by mounting it, or we can extract the contents of the iso file to a CD, DVD, or a USB via burning the iso file.

    Moreover, we can flash iso files onto a DVD, CD, or USB to create a bootable device that will help install an operating system onto your PC.

    Lastly, we can create our iso file that will package all the contents according to you. However, that is not something that we would often want to do.
