How to Restore Ubuntu in the Windows Boot Manager

If you’ve installed Ubuntu alongside Windows 11 but find it missing from the boot menu, you’re not alone. This issue often arises when the Windows Boot Manager takes precedence, typically after updates or reinstallations. Fortunately, you can manually add Ubuntu back to the boot manager without needing to reinstall it or use a USB drive. In this guide, we’ll walk you through the step-by-step process to restore your Ubuntu boot option easily and effectively.

Before we begin, ensure you have administrative privileges on your Windows system, as you’ll need to run commands in the Command Prompt. This guide assumes you are using Windows 11 and have Ubuntu installed, ready to be added back to the boot menu.

Step 1: Open Command Prompt as Administrator

To start the process, you’ll need to access the Command Prompt with administrative rights. Follow these steps:

Click on the Start menu.
Type cmd or Command Prompt.
Right-click on Command Prompt from the search results and select Run as administrator.

This will open a Command Prompt window with elevated privileges, allowing you to execute the necessary commands.

Step 2: Add Ubuntu to the Boot Manager

Now that you have the Command Prompt open, you will input a specific command to add Ubuntu back to the Windows Boot Manager.

Type the following command and press Enter:

BCDEdit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

This command tells the Windows Boot Manager to load the Ubuntu bootloader first. If your system has secure boot enabled, you may need to use an alternative command. If that’s the case, type the following instead:

BCDEdit /set {bootmgr} path \EFI\ubuntu\shimx64.efi

After executing the command, you should see a confirmation message indicating the operation was successful.

Step 3: Restart Your Computer

To apply the changes, restart your computer. Upon reboot, you should see the Ubuntu option in the boot menu alongside Windows 11. If you don’t see it immediately, give it another restart, as sometimes it takes a moment for changes to take effect.

Step 4: Troubleshooting Missing Ubuntu Option

If Ubuntu still doesn’t appear in the boot menu after following the above steps, you may need to check your BIOS/UEFI settings. Make sure that:

Secure Boot is disabled.
Your boot order is set to prioritize the Windows Boot Manager.

Adjustments in these settings can often resolve booting issues. Additionally, you can consider using third-party tools like rEFInd for more advanced boot management.

Extra Tips & Common Issues

Here are some pointers to keep in mind:

Always keep your system updated, as updates may alter boot configurations.
Back up important files before making changes to your boot settings.
Consult the Ubuntu community forums or support for additional help if you encounter persistent issues.

Conclusion

By following these steps, you should be able to restore Ubuntu to your Windows Boot Manager successfully. This process not only enhances your accessibility to both operating systems but also ensures that you can manage them effectively. If you encounter any issues or have questions, don’t hesitate to seek further assistance from online resources or community forums.
