Summary: If you get an operating system, software package, or install media through the internet, it is most likely available in ISO format. But you generally can’t use an ISO file directly to install a bootable OS. For that, you need to convert ISO to bootable disk first, somehow. This guide will show you the most effective methods to convert ISO files into bootable media, both manually and an advanced way of doing so.

ISO file is a digital or virtual replica of an optical disc, like your CD, DVD, or Blu-ray. It’s got every piece of data that was saved to your original disc, file system and all, boot information included. For this file to be recognizable and properly integrated when you install or run an operating system from it. The physical media that contains the boot files must have a sector size of 512 bytes
