How to Add Ubuntu to Windows Boot Manager

Welcome to AA Technical! If you've installed Ubuntu alongside Windows 11 but can't see it in the boot menu, this guide will show you how to add Ubuntu to the Windows Boot Manager. By following these steps, you'll be able to seamlessly switch between Windows and Ubuntu.

Prerequisites

1. Verify Ubuntu Installation:
   • Open Disk Management by right-clicking the Start button and selecting Disk Management.
   • Check for a separate partition labeled EFI partition or EXT4 partition.

Steps to Add Ubuntu

Step 1: Access EFI Partition

1. Open Command Prompt with administrative privileges.
2. Identify the EFI Partition:
   • Type diskpart and hit enter.
   • Type list disk and hit enter.
   • Identify your main hard drive and select it (Example: select disk 2).
   • Type list partition and hit enter.
   • Look for a small partition (100-500 MB) labeled as EFI system partition.
   • Note the partition number and select it (select partition [your partition number]).
   • Assign a temporary drive letter (Example: assign letter=M).

Step 2: Add Ubuntu to Boot Manager

1. Add Ubuntu Entry:
   • Type the following command to add the Ubuntu boot entry:

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

   • If the above command fails, create an entry manually:

     bcdedit /create /d "Ubuntu" /application bootsector
     

   • Set the device and path using:

     bcdedit /set {your new GUID} device partition=[your drive letter]:
     bcdedit /set {your new GUID} path \EFI\ubuntu\grubx64.efi
     

   • Display the loader:

     bcdedit /displayorder {your new GUID} /addlast
     

Step 3: Verify Ubuntu Is Added

1. Check the Boot Manager:
   • Type bcdedit /enum to verify that Ubuntu is listed.
2. Restart your computer to see if Ubuntu appears in the Windows Boot Manager.

Troubleshooting

• BIOS Settings:
  • Check your BIOS boot order by pressing F2, F12, Escape, or Delete at startup.
  • Ensure that Secure Boot is disabled.
