Creating a bootable pendrive (USB drive) can be incredibly useful, whether you need to install a new operating system, run diagnostic tools, or simply have a portable OS on the go. In this guide, I'll walk you through the steps to make a bootable USB drive on both Windows and macOS.
What You Will Need:
- USB Drive: At least 8GB of storage capacity.
- ISO File: The disk image of the operating system or tool you want to boot from (e.g., Windows, Linux, etc.).
- Bootable USB Creator Software: Tools like Rufus (Windows) or Balena Etcher (Windows, macOS, Linux).
Step-by-Step Guide for Windows
Download Rufus:
- Visit the Rufus website and download the latest version.
Insert the USB Drive:
- Connect the USB drive to your computer. Ensure there is no important data on it, as it will be erased during the process.
Open Rufus:
- Run the Rufus application. No installation is needed.
Select the USB Drive:
- Under "Device," choose your USB drive from the drop-down menu.
Choose the ISO File:
- Click on the "Select" button next to "Boot selection" and locate the ISO file you downloaded.
Configure Partition Scheme:
- Choose the partition scheme (MBR for BIOS or GPT for UEFI, depending on your needs).
Start the Process:
- Click on "Start" to begin creating the bootable USB. Rufus will warn you that all data on the drive will be erased; click "OK" to proceed.
Wait for Completion:
- Once done, you will see a message saying "Ready." Your USB drive is now bootable!
