Creating a bootable USB drive is a useful skill, especially if you need to install or repair an operating system. Here’s a simple step-by-step guide to help you create a bootable USB drive.
What You’ll Need
- A USB drive (at least 8 GB for most operating systems)
- A computer with an internet connection
- The ISO file of the operating system you want to install

- Download the Tool: Visit the tool’s official website and download it.
Step 3: Prepare the USB Drive
