Fixing Ubuntu Not Showing in Windows 11 Boot Manager: A Step-by-Step Guide
If you’ve successfully installed Ubuntu alongside Windows 11 but can’t see it in the boot menu, you’re not alone. Many users encounter this issue where their system boots directly into Windows without displaying the option to select Ubuntu. This guide will walk you through the necessary steps to manually add Ubuntu to the Windows Boot Manager, ensuring a seamless dual-boot experience without the need for a USB drive or reinstalling anything.
Before you start, ensure you have administrative privileges on your Windows system as you will be required to make changes that affect system boot configurations. This guide will cover essential tools like the Disk Management utility, Command Prompt, and the bcdedit command to create boot entries for Ubuntu. Let’s get started!
Step 1: Verify the Installation of Ubuntu
Before making any changes, confirm that Ubuntu is installed correctly. To do this, open the Disk Management utility:
- Right-click the Start button and select Disk Management.
- Check for a separate partition labeled as EFI System Partition (usually 100-500 MB) or an EXT4 partition for Ubuntu. If you find these, your installation is in good shape.
Step 2: Open Command Prompt with Administrative Privileges
Next, you need to open the Command Prompt to execute commands that will modify the boot configuration:
- Press Windows + X and select Windows Terminal (Admin) or Command Prompt (Admin).
Step 3: Identify the EFI Partition
To add Ubuntu to the boot manager, identify the EFI partition where your boot loader files are stored:
- In the Command Prompt, type
diskpartand press Enter. - Next, type
list diskand press Enter to display available disks. - Select your main hard drive by typing
select disk X(replace X with the disk number) and hit Enter. - Type
list partitionand press Enter. - Look for a partition around 100-500 MB labeled as EFI.
- Note the partition number and select it using
select partition Y(replace Y with your partition number). - Assign a temporary drive letter by typing
assign letter=Z(you can choose any letter between M and Z) and press Enter. - Exit the diskpart utility by typing
exitand pressing Enter.
Step 4: Add Ubuntu to the Windows Boot Manager
Now that you have access to the EFI partition, you can add Ubuntu to the boot manager:
- In the Command Prompt, type the following command to add Ubuntu to the boot manager:
- Press Enter.
- If you encounter issues, you may create an entry manually by entering:
- After that, set the device and path with:
- Finally, set the path to the Ubuntu boot loader:
- Press Enter after each command.
bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi
bcdedit /create /d "Ubuntu" /application bootsector
bcdedit /set {new-guid} device partition=Z: (replace {new-guid} with the ID generated from the previous command).
bcdedit /set {new-guid} path \EFI\ubuntu\grubx64.efi
Step 5: Verify the Configuration
To check if the Ubuntu entry has been successfully added, type:
bcdedit
Look for an entry named “Ubuntu”. If it appears, your configuration is correct. Restart your computer to see if Ubuntu shows up in the boot menu.
