Create a bootable USB stick on Ubuntu
Creating a bootable Ubuntu USB stick is very simple, especially from Ubuntu itself, 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 Microsoft Windows and Apple macOS.
2. Requirements
- A 4GB or larger USB stick/flash drive
- Ubuntu Desktop 14.04 or later installed
- An Ubuntu ISO file. See Get Ubuntu for download links
3. Launch Startup Disk Creator
We’re going to use an application called ‘Startup Disk Creator’ to write the ISO image to your USB stick. This is installed by default on Ubuntu, and can be launched as follows:
- Insert your USB stick (select ‘Do nothing’ if prompted by Ubuntu)
- On Ubuntu 18.04 and later, use the bottom left icon to open ‘Show Applications’
- In older versions of Ubuntu, use the top left icon to open the dash
- Use the search field to look for Startup Disk Creator
- Select Startup Disk Creator from the results to launch the application
4. ISO and USB selection
When launched, Startup Disk Creator will look for the ISO files in your Downloads folder, as well as any attached USB storage it can write to.
It’s likely that both your Ubuntu ISO and the correct USB device will have been detected and set as ‘Source disc image’ and ‘Disk to use’ in the application window. If not, use the ‘Other’ button to locate your ISO file and select the exact USB device you want to use from the list of devices.
Click Make Startup Disk to start the process.
5. Confirm USB device
Before making any permanent changes, you will be asked to confirm the USB device you’ve chosen is correct. This is important because any data currently stored on this device will be destroyed.
After confirming, the write process will start and a progress bar appears.
6. Installation complete
That’s it! You now have Ubuntu on a USB stick, bootable and ready to go.
If you want to install Ubuntu, take a look at our install Ubuntu desktop tutorial.

10 Useful Tools to Create Bootable USB from an ISO Image
CD and DVD writers are a thing of the past. You are not likely to find them in modern-day laptops. If your goal is to create a bootable medium, then creating a bootable USB drive from an ISO file remains your best option.
There are quite a number of tools that can help you create a bootable USB drive. Some will even go further and let you create a multi-boot USB drive where you get to choose the OS that you want to install.
Here are some of the widely-used utilities for creating a bootable USB drive from an ISO file in Linux desktop systems.
1. Rufus
We start off our list with Rufus which is arguably one of the most popular bootable USB creation utilities. It’s a free tool that you can download and create bootable USB pen drives, memory sticks, etc. It is particularly helpful when you want to create a USB installation medium from an ISO image or work on a system with no OS installed.
Rufus is a portable utility that comes with a small footprint – 1.3MB only. No installation is required. You just need to double-click on the executable file to launch the UI and start creating your USB bootable medium from an ISO image of your choice (both Windows and Linux).
Unfortunately, Rufus is only supported on Windows and the developer has not yet ported it to Linux as yet. If you are looking for an alternative that works on Linux, read on.
2. UNetbootin
UNetbootin is a free and cross-platform utility for creating live bootable USB drives using an ISO image from all the major Linux distributions, even the lesser-known ones such as Tails, and AntiX.
It doesn’t employ distribution-specific rules for creating bootable USB drives, and therefore, most of the Linux ISO images should load without a problem.
Apart from creating a Live bootable medium, you get other system repair tools and utilities for example:
- Parted Magic
- SystemRescueCD
- Smart Boot Manager
- Dr.Web AntivirusF-Secure Rescue CD
- Super Grub Disk
- Backtrack
- Ophcrack
3. Balena Etcher
Developed & Maintained by the Balena team, Balena Etcher is a free and open source for writing image files such as .img and .iso onto USB drives and creating Live bootable pen drives and SD cards.
Etcher is a cross-platform tool and is available for download on Windows, macOS, and Linux (both 32-bit and 64-bit). It provides a very elegant yet simple UI that provides a smooth experience while writing your image files.
4. Ventoy
Ventoy is yet another utility that lets you not only create an ordinary USB bootable medium but also allows you to create a multiboot USB drive with several OS options.
In fact, Ventoy takes away the need to format your USB drive over and over again. Simply copy the ISO file to your Pendrive drive and boot it. You can copy multiple ISO files concurrently and Ventoy will provide a boot menu to select your preferred image to boot from. Ventoy supports over 420 ISO files.
- Cross-platform (Windows, Linux).

And many more. Check out Ventoy’s additional features.
5. Universal USB Installer
Abbreviated as UUI, Universal USB Installer is a Live Linux Bootable USB Creator Software that allows you to easily create a bootable USB from your favorite Linux distribution or Windows installer. It runs only on the Windows operating system.
In addition to that, you also get additional tools such as USB Boot Rescue tools such as Comodo and BitDefender Rescue CD, and bootable software such as Hirens Boot CD.
6. Yumi
Yumi – short for ‘Your Universal Multiboot Installer’ – is another tool that you can leverage to create a multiboot USB drive. It’s the predecessor of the Universal USB installer and allows you to create a Multiboot USB Flash Drive containing multiple ISO files on the fly and start using it to boot your preferred Live Linux OS.
Key features of Yumi USB creator include:
- Runs only on the Windows operating system.
- An option to reformat your USB drive.
- Support for both Legacy and UEFI BIOS modes.
- Affinity for Ubuntu-derived Distributions.
- Download links to make it easy to get the related ISO files.
- A website link to help you learn more about the YUMI.
- A feature to remove installed items on the USB drive to facilitate cleanup.
7. PowerISO
PowerISO is a robust and fully-featured application for burning CDs/DVDs. In addition, It allows you to extract, burn, create, encrypt, compress, and convert ISO images and mount them on an external drive.
It provides an all-in-one solution allowing you to do whatever you want with your files.
At a glance, PowerISO allows you to:
- Supports Windows, Linux, and macOS.
- Create a bootable USB drive from an ISO image.

10. ImageUSB Writer
Last on the list is the ImageUSB Writer. Just like GNOME multi-writer and multi-boot USB, this is a free utility for Windows systems only that allows you to write an ISO file concurrently to several USB devices. It also supports direct imaging between the devices.
ImageUSB writer is also a perfect tool for mass duplication of USB flash drives. The application is also capable of reformatting a USB device, as well as MBR and GPT entries for wider disk space.
That was a roundup of some of the utilities that you can leverage to create a bootable USB drive from an ISO image in Linux. We have compiled tools that work on both Linux and Windows in case you are working on either system. That is all for now. Your feedback is highly welcome.
Create a bootable USB stick with Rufus on Windows
This tutorial will show you how to create a bootable USB stick on Microsoft Windows using Rufus.
For most users we recommend balenaEtcher instead of Rufus which is simpler to use and also available on MacOS and Ubuntu. Instructions are now included in the primary Install Ubuntu Desktop tutorial.
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
- A 4GB 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! If using Windows XP or Vista, download version 2.18 of Rufus.
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 selected is incorrect (perhaps you have multiple USB storage devices), select the correct one from the device field’s drop-down menu
You can avoid the hassle of selecting from a list of USB devices by ensuring no other devices are connected.
4. Select the Ubuntu ISO file
To select the Ubuntu ISO file you downloaded previously, click the SELECT to the right of “Boot selection”. If this is the only ISO file present in the Downloads folder you will only see one file listed.
Select the appropriate ISO file and click on Open.
5. Write the ISO
The Volume label will be updated to reflect the ISO selected.
Leave all other parameters with their default values and click START to initiate the write process.
6. Additional downloads
You may be alerted that Rufus requires additional files to complete writing the ISO. If this dialog box appears, select Yes to continue.
7. Write warnings
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 also warn you 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.
If your USB stick contains multiple partitions Rufus will warn you in a separate pane that these will also be destroyed.
8. Writing the ISO
The ISO will now be written to your USB stick, and the progress bar in Rufus will give you some indication of where you are in the process. With a reasonably modern machine, this should take around 10 minutes. Total elapsed time is shown in the lower right corner of the Rufus window.
9. Installation complete
When Rufus has finished writing the USB device, the Status bar will be filled green and the word READY will appear in the center. Select CLOSE to complete the write process.
Congratulations! You now have Ubuntu on a USB stick, bootable and ready to go.
To use it you need to insert the stick into your target PC or laptop and reboot the device. It should recognise the installation media automatically during startup but you may need to hold down a specific key (usually F12) to bring up the boot menu and choose to boot from USB.
