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
Create a bootable Ubuntu USB stick on Windows is very simple and we’re going to cover the process in the next few steps.
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
3. USB selection
Perform the following to configure your USB device in Rufus:
- Launch Rufus
- Insert your USB stick
- Rufus will update to set the device within the Device field
- If the Device is incorrect, select the correct one from the device field’s drop-down menu
4. Partition scheme and ISO selection
For best compatibility with newer hardware, keep the Partition scheme and target system type set as MBR partition scheme for UEFI. However, if you need to use the USB stick with older hardware, change this to MBR Partition Scheme for BIOS or UEFI.
To select the Ubuntu ISO file, click the optical drive icon alongside the enabled Create a bootable disk using field. This will open a file requester from which you can navigate to, and select, the ISO file.
5. Hybrid image confirmation
Leave all other parameters with their default values and click Start to initiate the write process.
You will then be alerted that Rufus has detected that the Ubuntu ISO is an ISOHybrid image. This means the same image file can be used as the source for both a DVD and a USB stick without requiring conversion.
Keep Write in ISO Image mode selected and click on OK to continue.
Rufus will warn that all data on your selected USB device is about to be destroyed. This is a good moment to double check you’ve selected the correct device before clicking OK when you’re confident you have.
6. Write the ISO
The ISO will now be written to your USB stick, and the progress bar in Rufus will give you some indication of how long this will take. With a reasonably modern machine, this should take around 3 minutes.
7. Installation complete
Rufus will complete the write process and silently drop-back to its default window.
Congratulations! You now have Ubuntu on a USB stick, bootable and ready to go.
