UNetbootin allows you to create bootable Live USB drives for Ubuntu and other Linux distributions without burning a CD.

You can either let UNetbootin download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file.


UNetbootin can create a bootable Live USB drive

It loads distributions either by downloading a ISO (CD image) files for you, or by using an ISO file you've already downloaded.

Using UNetbootin

Select an ISO file or a distribution to download, select a target drive (USB Drive or Hard Disk), then reboot once done. If your USB drive doesn't show up, reformat it as FAT32.

If you used the 'USB Drive' install mode: After rebooting, boot from the USB drive. On PCs, this usually involves pressing a button such as Esc or F12 immediately after you turn on your computer, while on Macs, you should hold the Option key before OSX boots.

If you used the 'Hard Disk' install mode: After rebooting, select the UNetbootin entry from the Windows Boot Menu.

Supported Distributions

UNetbootin has built-in support for automatically downloading and loading the following distributions, though installing other distributions is also supported:

UNetbootin can also be used to load various system utilities, including:

Installing Other Distributions Using UNetbootin

Download and run UNetbootin, then select the 'disk image' option and supply it with an ISO (CD image).

UNetbootin doesn't use distribution-specific rules for making your live USB drive, so most Linux ISO files should load correctly using this option. However, not all distributions support booting from USB, and some others require extra boot options or other modifications before they can boot from USB drives, so these ISO files will not work as-is. Also, ISO files for non-Linux operating systems have a different boot mechanism, so don't expect them to work either.


Distribution X isn't on the list of supported distributions, will it work?

» Maybe, see Installing Other Distributions Using UNetbootin.

UNetbootin isn't able to download the distribution, what should I do?

Download the ISO straight from the website, then provide it to UNetbootin via the diskimage option.

My USB stick isn't booting, what should I do?

Reformat the USB drive as FAT32, then use UNetbootin again to put your distribution on the USB stick.

My USB stick/hard drive isn't detected, what should I do?

Reformat the USB drive as FAT32, then use UNetbootin again. If it still isn't showing up, use the targetdrive command line option.

How do I use UNetbootin from the command line?

» See UNetbootin Command Line Options.

How does UNetbootin work, and what does it do?

» See How UNetbootin Works.

» See USB Drive and Hard Disk Install Modes.

Where can I report bugs, submit patches, etc?

First, make sure you are using the latest version available on this website.

» See Github Issues to file a bug report.

» See Github Pull Requests to submit a patch.

Does UNetbootin have any spyware, viruses, trojans, or other malware?

No; though some anti-virus products may raise 'Trojan.generic' warnings due to the auto-uninstall feature, these are false positives. Just make sure you obtain UNetbootin from this site, not some shady third-party source. If you're absolutely paranoid, you can check the source code and compile it yourself.

What translations are available, and how can I use them?

A number of translations are included in the latest UNetbootin release. See the Translations Page for the status of each.

If a translation corresponding to your system's native language has already been included into UNetbootin, it should automatically load the corresponding translation. Alternatively, you can force the language to use via the lang=es command-line option, where you substitute es with the the 2-letter ISO 639-1 code for your language.

Can I help translate?

If you'd like to help translate this website, join the project on Transifex, then edit translations either on this website or on Transifex.

If you'd like to help translate the UNetbootin program itself, please use Launchpad Translations. If you are new to Launchpad, you will first have to join the corresponding Ubuntu Translators group for the language you intend to translate. For information on using the Launchpad Translations system, see the translations help page.

Removal Instructions (Applicable only to Hard Disk installs)

If using Windows, UNetbootin should prompt you to remove it the next time you boot into Windows. Alternatively, you can remove it via Add/Remove Programs in the Control Panel.

If using Linux, re-run the UNetbootin executable (with root priveledges), and press OK when prompted to uninstall.

Removal is only required if you used the 'Hard Drive' installation mode; to remove the bootloader from a USB drive, back up its contents and reformat it.

Uninstalling UNetbootin simply removes the UNetbootin entry from your boot menu; if you installed an operating system to a partition using UNetbootin, removing UNetbootin will not remove the OS.

Boot Usb Mac Os Sierra

To manually remove a Linux installation, you will have to restore the Windows bootloader using 'fixmbr' from a recovery CD, and use Parted Magic to delete the Linux partition and expand the Windows partition.

Where's the source code, and how can I compile or modify it?

Source code is on Github, though you may prefer a tarball of the latest release.

Since Microsoft introduced Windows 11 in June this year, a lot of folks, especially software developers and tech fans are eager to see how Windows 11 works! Recently, we finally got the leaked version of Windows 11 and able to install it on a PC by creating a Windows 11 bootable USB.

In this article, we will share all the steps how to create a Windows 11 bootable USB on Mac, which is much more challenging than doing the same task this task on a Windows machine. You can check our previous post for making a Windows 11 bootable installer on PC.

Before proceeding to the details, please make sure you already have a Windows 11 ISO image. If not, please download Windows 11 ISO file by following the suggestions in another article written by our senior editor.

In addition, please prepare for USB drive. USB 3.0 or about is preferred as it will be much faster for file copying.

Now, it is time to see how to create a Windows 11 bootable USB on Mac with different tools.

Create Windows 11 Bootable on Mac in Terminal

The first method we will be talking about is Terminal app, a command line based utility for performing tasks with text commands. Almost all the activities being done under graphics user interface can be achieve in Terminal app. We will be going to use Terminal to create a Windows 11 bootable USB on Mac.

Step 1: Insert a USB drive on Mac and eject other USB devices at this time to avoid confusion.

Step 2: Input the following command to get the physical drive name of target USB drive.

diskutil list external

In our example, the physical volume name of USB is disk3.

Step 3: Format the USB drive to MS-DOS with MBR boot scheme, which is mandatory to hold Windows OS files. WIN11 is the volume name of USB drive and disk3 is the physical USB drive we got from previous step.

diskutil eraseDisk MS-DOS 'WIN11' MBR disk3

Step 4: After that, mount the Windows 11 ISO on Mac, assuming it is saved in Downloads folder. You will also see the mounted volume name at left sidebar of Finder.

hdiutil mount ~/Downloads/Windows_11.iso

Step 5: At this stage, we need to get the mounted volume name for USB drive and Windows 11 ISO with ls command. CCCOMA_X64FRE_EN_US_DV9 is the volume name of Windows 11 ISO and WIN11 is the volume name of USB drive.

ls /Volumes

Step 6: Finally, copy all files and folders from mounted Windows 11 volume to USB drive.

cp -rp /Volumes/CCCOMA_X64FRE_EN_US_DV9/* /Volumes/WIN11/

When you see a new line of command input in Terminal, it means the file copying is finished.

That's all! This is not difficult task if you are playing commands on Mac from time to time. If not, please consider the following methods instead, which could be much simpler!


  • 100% free.
  • macOS built-in app.


  • Pure text command interface.
  • Not easy to get started.
  • More steps and take more time.
  • Unable to handle large ISO files.
  • More risky than Boot Camp and ISO Editor.

Make Windows 11 Bootable on Mac via Boot Camp Assistant

Boot Camp Assistant, Boot Camp for short, is another system app that comes with macOS. The main usage is to create a Windows dual boot on Mac. Besides that, it is also capable of creating Windows bootable USB.

[Updates]: Creating Windows bootable USB feature is no longer available from Boot Camp app since macOS Big Sur. You have to remove all attached external USB devices before using Boot Camp app as the screenshot shows. However, you can still install Windows on Mac with Boot Camp.

The following tutorial is completed on a Intel Mac that is running macOS Catalina.

Step 1: Open Boot Camp Assistant app from Launchpad and click Continue button to process. It will remove old time machine backups and cached iCloud files to make more room for further task.

Step 2: Wait about one minute. From Select Tasks Window, please check Create a Windows 10 or later install disk and click Continue to proceed.

Step 3: Click Choose... button to load Windows 11 ISO into Boot Camp and select the USB drive name.

Step 4: Finally, click Continue button to erase the USB disk and start copying Windows files to USB. At the end of burning process, Boot Camp will download Windows Support Software. This will be a greta help if you are trying to run Windows 11 on Mac.

Other Apps You Can Try Out

I am pretty confident to say you can successfully make a Windows 11 bootable USB with one of the apps suggested above in most of the cases. However, if you had a bad luck, please don’t be frustrated as there are more apps you can test it out.

SysGeeker WonderISO: This is another GUI based application being used for creating Windows bootable USB. The steps are quite straightforward and no hassle at all. The only drawback is that it is a premium app. This means you have to pay a few bucks for a commercial license.

UNetBootin: It is a famous free tool for making bootable USB from all kinds of ISO files. You can use this free utility on Mac, Windows and Linux computers. However, the user interface is bit weird and you need to spend sometime to figure out how it works.

Virtual Machine Software: There are tons of free software available on Windows when it comes to create bootable USB, such as Media Creation Tool, Rufus or Etcher. This is a great alternative solution if you have a Windows virtual machine set up on your Mac. If not, then it is easy to create one with virtual machine apps, such as Virtual Box, Parallels Desktop.

No matter which method you are going to use , you will see Windows 11 setup screen upon success when booting the computer from USB. You can now follow the instructions to get Windows 11 installed on that computer.

Boot Camp is a nice consideration when you are using a Mac running an old version of macOS. If the task could be completed with Terminal or Boot Camp app, then UUByte ISO Editor is your best option now!

Common Issues and Bug Fix

Q: USB Drive Not Seen by Mac

Mac can only recognize external drives formatted by FAT, HFS, APFS and exFAT. Other drives, for example, NTFS drive, which is mostly used on Windows PC, is not supported by Mac. You have to format this USB to FAT with Disk Utility app to make it working on Mac.

Q: USB Not Bootable After Burning

This error mostly comes with Terminal app. In this case, you should change the disk formatting command from MBR to GPT. On modern computers with UEFI booting, GPT should be the default partition scheme.

Q: Boot Camp Not Enough Space Error

You will see a warning message (The starup disk does not have enough space to be partitioned) when opening Boot Camp Assistant app. This happens when the free space on your Mac is less than 42 GB. Please click OK button to ignore this error. This has nothing to do with the future steps for creating bootable USB.
