How to Make Bootable USB from ISO

We used to install Microsoft Windows by disk or CD- or DVD-ROM, but now it either comes preinstalled on the system partition of a new computer or you get it directly online. However, if a person still needs an external installation medium, one of the easiest and compact tools to use is a bootable USB drive.

A bootable USB drive has plenty of uses, but booting the computer if it will no longer start itself because of a virus, serious system failure, defective hard drive, or partition problems is its most crucial use. This small piece of hardware can also be used to upgrade Windows 7 or 8 to Windows 10 if a previously automatic upgrade doesn’t function correctly as it can host an entire operating system and/or a recovery system. Thus, you can use it to successfully reboot and repair the computer.

In fact, it is a kind of a portable operating system which you can use on a foreign computer without having to bother with the operating system already installed. So, you can use your favorite Windows version with all your personal data and tools on any computer. This tool can be used to use a recovery system to repair your computer, boot after an emergency, clean the reinstallation of the operating system, upgrade an old operating system to Windows 10, use your preferred OS on a foreign computer, and store an image of the operating system.

On the other hand, ISO files or image files are archive files which contain a snapshot of all the required files and content for a particular operating system, software, or DVD. They are commonly used for backing up optical discs or for distributing large file sets to be burned to an optical disc.

Knowing how to create bootable media from an ISO file is very important and the process isn’t as simple as it seems. It requires more than just copying the ISO file to another location. In fact, it needs a special utility. Thus, we decided to show you the best ways how to create a bootable USB drive from an ISO file. However, keep in mind that some of these methods require significant knowledge of ISO files and how they are burned to create bootable media.

How to Make Bootable USB from ISO

There are no commercial USB drives which are suitable for this because they are only loaded with a single file system. Moreover, these commercial tools lack a master boot record which is crucial for booting most computers, especially the ones with a basic input/output system (BIOS). Thus, this means that you will have to make a new USB stick bootable on your own.

You can make a bootable hardware tool either manually or using automated tools. Both methods are doable, even if you aren’t an expert. So, no matter which method you choose, you will always need:

  • The Windows utility program DiskPart or an external tool with the same functions.
  • A USB drive with at least 4GB of storage
  • An ISO file for the desired OS that contains all setup files that you need for installation.
