In today’s digital age, having a bootable USB drive can be a lifesaver, especially when you need to install or repair an operating system. With the rise of ISO files, creating a bootable USB has become a relatively straightforward process. In this article, we will walk you through the steps to create a bootable USB from an ISO file, covering the necessary tools, preparation, and execution.
Understanding ISO Files and Bootable USBs
Before we dive into the process, it’s essential to understand what ISO files and bootable USBs are.
What is an ISO File?
An ISO file is a digital copy of a CD, DVD, or Blu-ray disc. It’s a single file that contains all the data from the disc, including the file system, folders, and files. ISO files are often used to distribute software, operating systems, and other digital content.
What is a Bootable USB?
A bootable USB is a USB drive that can be used to boot a computer, allowing you to install or repair an operating system, run diagnostic tools, or access data on the computer. Bootable USBs are created by writing the contents of an ISO file to a USB drive, making it possible to boot from the USB drive.
Preparing Your Tools and Materials
To create a bootable USB from an ISO file, you’ll need the following tools and materials:
Required Tools and Materials
