1. Overview
With a bootable Ubuntu USB stick, you can:
- Install or upgrade Ubuntu
- Test out the Ubuntu desktop experience without touching your PC configuration
- Boot into Ubuntu on a borrowed machine or from an internet cafe
- Use tools installed by default on the USB stick to repair or fix a broken
configuration
Creating a bootable Ubuntu USB stick from Microsoft Windows is very simple and we're going to cover the process in the next few steps.
Alternatively, we also have tutorials to help you create a bootable USB stick from both Ubuntu and Apple macOS.
2. Requirements
You will need:
- A 2GB or larger USB stick/flash drive
- Microsoft Windows XP or later
- Rufus, a free and open source USB stick writing tool
- An Ubuntu ISO file. See Get Ubuntu for download links
Take note of where your browser saves downloads: this is normally a directory called ‘Downloads' on your Windows PC. Don't download the ISO image directly to the USB stick!
