Boot from USB in Ubuntu: A Step-by-Step Guide

Ubuntu is one of the most popular Linux distributions, and it’s widely used by developers, programmers, and power users. One of the most common tasks that Ubuntu users need to perform is booting from a USB drive. This can be useful for installing a new operating system, running a live session, or troubleshooting issues with the current installation. In this article, we’ll show you how to boot from a USB drive in Ubuntu.

Why Boot from USB in Ubuntu?

There are several reasons why you might want to boot from a USB drive in Ubuntu. Here are a few:

  • Installing a new operating system: If you want to install a new operating system on your computer, you’ll need to boot from a USB drive that contains the installation media.
  • Running a live session: Ubuntu allows you to run a live session from a USB drive, which means you can try out the operating system without installing it on your computer.
  • Troubleshooting issues: If you’re experiencing issues with your current Ubuntu installation, booting from a USB drive can help you troubleshoot the problem.
  • Recovering data: If your computer won’t boot normally, you can use a USB drive to boot into a live session and recover your data.

Requirements for Booting from USB in Ubuntu

Before you can boot from a USB drive in Ubuntu, you’ll need to make sure you have a few things:

  • A USB drive: You’ll need a USB drive with at least 2GB of free space. The USB drive should be empty, as the boot process will erase all data on the drive.
  • Ubuntu installation media: You’ll need to download the Ubuntu installation media from the official Ubuntu website. This can be an ISO file or a physical DVD.
  • A computer with a USB port: You’ll need a computer with a USB port to plug in the USB drive.

Creating a Bootable USB Drive

  • Download Rufus or Etcher: You can download Rufus or Etcher from their official websites.
  • Insert the USB drive: Insert the USB drive into your computer.
  • Launch Rufus or Etcher: Launch Rufus or Etcher and select the USB drive from the list of available devices.
  • Select the Ubuntu ISO file: Select the Ubuntu ISO file that you downloaded earlier.
  • Start the process: Start the process of creating a bootable USB drive. This may take a few minutes.

Configuring the BIOS to Boot from USB

Once you’ve created a bootable USB drive, you’ll need to configure the BIOS to boot from USB. Here’s how to do it:

Boot Order vs. Boot Priority

When configuring the BIOS to boot from USB, you may come across two options: boot order and boot priority. Here’s what they mean:

  • Boot order: The boot order refers to the order in which the BIOS checks for boot devices. For example, if the boot order is set to USB, CD/DVD, and then hard drive, the BIOS will first check the USB drive for a bootable device, then the CD/DVD drive, and finally the hard drive.
  • Boot priority: The boot priority refers to the priority given to each boot device. For example, if the boot priority is set to USB high, CD/DVD medium, and hard drive low, the BIOS will give priority to the USB drive when booting.
