How to make a bootable Linux USB Drive on PC or Mac

Configurare noua (How To)

Situatie

On Windows 10 or 11, we recommend using Rufus. It’s been around for a long time and is well known as reliable and powerful.

To get started, go to the official Rufus website and scroll until you see a list of downloads. If you’re not sure which option to choose, go with the first one, as that applies to the vast majority of people.

After it finishes downloading, run the Rufus EXE file. It’ll ask for permission to make changes to your device, which is required for overwriting a disk like we’re about to do. When you get to Rufus’ dialog, plug in the USB drive you want to use, and then make sure the drive is selected in the “Device” field. Click the “Select” button next to the “Boot Selection” field and find the ISO or IMG file you downloaded. Double-check everything is correct—the other settings’ defaults are usually fine—then click the “Start” button at the bottom of the dialog.

Rufus may give you an “ISOHybrid” warning, but just go with the recommended option. If something goes wrong, you can always go back and redo it with the other option. Rufus will also warn you that the selected device’s data will all be destroyed, so confirm you chose the correct device and click OK.

Now all that’s left to do is wait. How long it takes depends on several factors, so go get a cup of coffee while Rufus does its work. When the writing was successful, Rufus’s status bar will change back to a green “Ready” message. You’re now ready to boot your Linux USB drive.

For writing Linux images to a USB drive on Mac, I recommend Raspberry Pi Imager. While it was designed for use by people installing OSes on their Raspberry Pi, in our testing it actually works well for any Linux distro meant for any computer.

To get started, go to the Raspberry Pi software page and look for the “Download for macOS” button to get the Imager DMG file. Double-click it and drag Raspberry Pi Imager over to your Applications folder.

Next, plug in your USB drive and launch Raspberry Pi Imager. You’ll see a few buttons. Ignore the first “Raspberry Pi Device” button and instead, under Operating System.

  • In the menu that appears, scroll until you see “Use Custom” and click it
  • Browse to the location of your Linux distro’s image file and open it.
  • With your image file selected, plug in your USB drive if you haven’t already, and in Imager click “Choose Storage”
  • You’ll see a list of available drives. In our example image, there’s only one, but you may see multiple. Select the drive you want to write the image to, making absolutely sure it’s the correct drive
  • With your image file and storage drive selected, click Next
  • You’ll be asked to confirm you don’t mind erasing everything on the USB drive you chose, so if you’re sure, click “Yes”
  • Now you just have to wait while the image writing happens. This can take several minutes, so be patient. When it’s complete, you’ll see a “Write Successful” message.

To make a bootable Linux drive on a computer that’s already running a Linux distribution, the most widely available and consistently reliable app that’s also easy to use is Impression. It’s available as a Flatpak, so it can be installed on any distro. You just need to already have installed Flatpak’s backend.

If you’re working in a headless Linux distro, or if you simply prefer to work in the terminal, you can make a bootable USB drive with the dd command. To install Impression, get it from the Flathub store. If your distro’s software manager already uses Flathub repos, you can find it there too by searching for Impression. If you want to install via the terminal, use this command:

flatpak install flathub io.gitlab.adhami3310.Impression

Using Impression is very simple. Plug in your USB drive if you haven’t already, and then launch Impression and click the “Open File” button, which will bring up your file browser.

Next, Impression will ask you to select the drive to install the image file on. Confirm you’ve selected the correct USB drive—you don’t want to accidentally overwrite a different drive with important files! Then click the “Write” button.

Impression will ask you one more time to confirm you’re OK with erasing the drive and overwriting with the image file. You’ll then likely be asked to enter your root password, which is typically required for Linux apps that are trying to erase a disk. Then you simply have to wait. The time it takes will depend on the size of the image file, your USB port’s data rate, and the write speeds of the thumb driver.

You’ll get a nice big writing completion confirmation when the process is done. Click “Finish”.If you’re removing the drive, confirm it’s been ejected, and you’re ready to go with your bootable Linux drive.

Other Options for Writing Images

If the apps I went over don’t work for you for some reason, there are other potential options. On Windows and Linux, I also recommend Ventoy, which actually lets you write multiple ISOs to the same drive. It’s meant for advanced users, and that’s why it isn’t the first thing I recommend.

On Linux, there are several options specific to certain distros, like Fedora Image Writer for Fedora, KDE Image Writer for Kubuntu and other KDE Plasma-enabled distros, and Mintstick for Linux Mint. You’re welcome to give them a try, especially if you’re already using a relevant distro. In my experience, though, it’s hit-and-miss whether they’re available in your repo and how well they work outside the Linux distros they were designed for.

Not sure what to do once you have your bootable Linux drive created?

To boot a PC from a USB drive, you’ll need to enter the BIOS. Check out our guides to entering the BIOS on Windows 10 or entering the BIOS on Windows 11. Linux folks can enter the BIOS by accessing the GRUB boot loader and selecting the item labeled “UEFI firmware settings” or something similar. Then look for the boot menu.
