Are you using Windows 11 on your desktop or laptop? Would you like to be able to install Ubuntu along with it? If so, this guide is for you! Follow us as we walk through how to dual-boot Ubuntu and Windows 11.

Download the latest version of Ubuntu

If you plan on dual-booting Ubuntu with your current Windows 11 installation, you'll need to get your hands on the latest Ubuntu ISO. Here's how to download it to your computer.

First, go up. Once on the desktop, locate the green "Download Ubuntu" button and select it with the mouse. Next, download Ubuntu 20.04.3 LTS or the latest version of Ubuntu.

Once you have downloaded the latest Ubuntu ISO file to your computer, you will be able to move on to the next step in the process.

Creating a bootable Ubuntu USB

To dual-boot Ubuntu with Windows 11, the ISO you downloaded must be flashed to a USB drive. There are many ways to do this on Windows 11, but by far the best way to do it is Etcher.

Because ? First, it's cross-platform and works on Windows, Mac OS, and Linux. Secondly, it's an easy-to-use program and will help you set up Ubuntu quickly on a USB.

  • To get started, download the latest application to your computer. So, install it and open it. Once open, plug in the USB flash drive and follow the detailed instructions below.
  • Find the "Flash from File" button with the mouse. Then, look for the Ubuntu ISO file on your computer.
  • Find the "select target" button within Etcher and click on it with the mouse. Then, choose your USB flash drive as the destination for Etcher to use.
  • Find the "Flash!" and click on it with the mouse. When you select this button, Etcher will start copying the Ubuntu ISO file to the USB drive. Be patient.

When the process is complete, restart your Windows 11 system. Then, load your computer's BIOS and select the Ubuntu USB to boot from.

Ubuntu / Windows 11 dual-boot setup

Now that Ubuntu is installed on a USB flash drive, you are ready to set it up alongside Windows 11. To get started, select the “Install Ubuntu” button within the Ubuntu installer. Then, follow the step by step instructions below.

  • Within the Ubuntu installer, select your keyboard layout (if the installer hasn't already automatically detected yours). When done, click the button below to continue.
  • After selecting a layout, Ubuntu will present you to the “Updates and Other Software” page. Select the "Normal" installation and "Install third party graphics software and Wi-Fi hardware and additional media formats".

After checking these two boxes, select the “Configure Secure Boot” button. Then, enter your secure boot password for Ubuntu. Click "Continue" when finished to proceed to the next step in the process.

  • On the “Installation Type” page, Ubuntu will show you that your computer already has “Windows Boot Manager” on it (AKA Windows 11.) Select “Install Ubuntu along with Windows Boot Manager” to set up a dual-boot.

Note: Ubuntu may not detect Windows 11 in the installer if Windows 11 has not been shut down safely. Restart Windows 11, then safely shut it down before attempting to load the Ubuntu USB installer.

  • After selecting the installation type, Ubuntu will ask you to choose how to split the hard drive. Using the slider, determine how big you want Ubuntu and Windows 11 to be on the drive.
  • Select the "Install Now" button to continue.
  • After setting up dual-boot, you need to choose your time zone. Find where you live on the global map and click the mouse. When you've set your time zone, click the "Continue" button and move on.
  • With the time zone set in Ubuntu, it's time to set the username, host name, and password. Using the keyboard, set your username, set a password and set your computer name.

Click the "Log In Automatically" button if you want Ubuntu to start automatically without the need for a password.

  • When you've set a password, your work is done. From here, sit back and allow Ubuntu to install on your computer. This process takes about 20 minutes (or more depending on the speed of the disc).
  • After installation is complete, restart your PC and disconnect the USB flash drive. Ubuntu is now installed alongside Windows 11.

Register Ubuntu in the BIOS

Since you dual-boot Windows 11 with Ubuntu, your system has a secure boot configuration. You need to register your Ubuntu installation in Safe Boot if your computer doesn't automatically prompt you.
