1. Install Linux from Windows 11

1. Create a new partition for Linux

  1. Press Windows Key + X and select Disk Management from the list.
  2. Select the drive that has extra space. Different Linux distributions have different requirements, so you’ll need about 50-100GB+ of space, depending on your needs.
  3. Right-click that drive and select Shrink Volume from the menu.
  4. Set the desired amount of space in MB in the Enter the amount of space to shrink in MB field and click the Shrink button.
  5. This will create unallocated space. Right-click the Unallocated space and select New Simple Volume.
  6. Set the Simple volume size in MB to the maximum possible value and click on Next.
  7. Now you just need to enter the desired letter for this drive and its label.
  8. Click the Finish button to complete the process.

In order to have a new partition created, you need to download Linux and create a bootable flash drive to install it.

2. Download Windows ISO and create a bootable flash drive

  1. Visit the download page of the distribution that you want to download. In our example, we used Linux Mint, but you can use any other distribution that you want.
  2. Select the source that you want to use and wait for the download to finish.
  3. Connect a USB flash drive to your PC.
  4. Once the ISO file is downloaded, download Rufus and run it.
  5. Select your flash drive from the list of devices.
  6. Click on Select and select the ISO file that you downloaded.
  7. Make sure that your settings are correct and click on Start.
  8. A confirmation dialog will appear asking you to format the drive, so be sure to format it to proceed.
  9. Wait for the process to finish.

Once the process is finished, you’ll have a bootable Linux flash drive ready. Now we can go on and install Linux.

3. Change the boot order and install Linux

  1. Restart your PC and press Del to access BIOS. Some motherboards use a different key, so be sure to check your PC’s documentation/motherboard documentation.
  2. Navigate to the Boot section, set your flash drive as the primary boot device, and save the changes.
  3. Once your PC restarts, you’ll be booted to Linux Mint live session. Select Install Linux Mint.
  4. Select the desired language and click on Continue.
  5. Up next, select your network if you want to download the third-party software for your graphics card, Wi-Fi, and media devices.
  6. Select Something else and choose Continue.
  7. You can now select the partition created at the beginning of this section. It’s crucial that you select the correct partition or else you might format the wrong drive and lose your data.
  8. Since Linux doesn’t work with Windows filetypes, you’ll need to edit the partition and set its file type to Ext4. Keep in mind that this process will format the partition and remove all files from it.
  9. Once the drive is converted to the Ext4, you can proceed and install Linux on it.
  10. Select your time zone.
  11. Select the desired keyboard layout.
  12. Now enter your user information. You can uncheck Encrypt my home folder option.
  13. Wait for the installation to finish.
  14. Once the installation is finished, click on Restart now button.
  15. Optional: Enter BIOS once again, and set your hard drive as the primary boot device.
  16. Once your PC boots, you’ll be asked to choose between Windows 11 and Linux, so pick the desired operating system and that’s it.

After completing all these steps, dual booting Windows 11 and Linux should be working properly. Of course, you’ll have to select the desired operating system every time you boot your PC.

We used Linux Mint in our example, but the steps are more or less the same for every Linux distribution.

Why is Linux missing after installing Windows in dual boot mode?

We’ve observed that Linux might be missing after installing Windows in dual boot mode. Although this can be extremely alarming, it’s expected because Windows will overwrite the Linux bootloader.

However, there’s a way to repair this:

  1. Press the boot menu key while your system boots. Usually, it’s F12, but it can change depending on your motherboard. Now select Ubuntu to boot to it. If this method doesn’t work, use Linux Live USB.
  2. Create a Linux Live USB.
  3. Boot from the Linux Live USB.
  4. Make sure that you’re connected to the Internet.
  5. Open the Terminal and run the following commands:
    sudo add-apt-repository ppa:yannubuntu/boot-repair
    sudo apt-get update
    sudo apt-get install -y boot-repair && boot-repair
  6. Now open Boot-Repair, you should find it in the list of installed applications, or type boot-repair in the Terminal.
  7. Select Recommended repair and that should hopefully fix the problem.

Some users claim that you can fix this issue by this method as well:

  1. Boot to Linux or start Linux from Live USB.
  2. Open Terminal and run the following command:
    sudo update-grub2
  3. Wait for the command to finish.
  4. After doing that, access BIOS and set Linux as the first boot disk.
  5. Save changes.

These instructions are intended for Ubuntu distributions, and other versions of Linux might require you to use different methods to repair the bootloader.

We have a dedicated guide on how to repair Windows 10 bootloader from Linux, so be sure to check it for more information.

Does Secure Boot interfere with Linux dual boot?

The Secure Boot capability is one of Windows 11’s requirements along with the TPM, so let us tell you how this could affect Linux computers and dual booting.

Secure Boot technology allows only the approved boot loaders to boot your PC in order to protect it from malware.

The issue arises because many versions of Linux aren’t compatible with Secure Boot, and since Secure Boot is a requirement for Windows 11, many were worried that Linux might not run in dual boot mode with Windows 11.

The answer is yes, Linux will be able to run long Windows 11, but you’ll have to use Linux that is compatible with Secure Boot, such as Ubuntu or Fedora, or disable the Secure Boot from the BIOS.

As you can see, to use Windows 11, you need to have Secure Boot capability, but you don’t have to keep this option enabled at all, which means that you can dual boot Linux without any issues.

Should I install Linux or Windows 11 first when dual booting?

If you want to dual boot Linux and Windows, it is usually a better option to install Windows first, and then create a new partition for Linux.

For starters, it’s a lot easier to create a Linux bootable drive and the necessary partitions from Windows, however, the biggest issue is the bootloader.

If you install Windows after Linux, you’re going to overwrite your bootloader and you won’t be able to boot to Linux until you repair the bootloader.

Therefore, we suggest installing Linux after your install Windows to avoid these types of problems. Are you using dual boot on your system? Let us know in the comments below.
