How Do I Remove Ubuntu From Dual Boot?

Ubuntu can be removed from the dual boot in various ways. To remove it, you’ll need the following:

Before going through the detailed methods, we suggest you boot into Windows instead of Ubuntu first. After that, follow these steps to have a single operating system on your device.

1. Delete from Disk Management Utility:

The Disk Management utility is a built-in tool that allows you to manage and manipulate disk partitions on your computer. It is useful for tasks like deleting the Ubuntu partition in a dual-boot system. To delete from the Disk Management utility in Windows 11, you can follow these steps:

  1. Press the Win+R key to open the Run dialog box
  2. Then type the following command and press Enter: diskmgmt.msc
    diskmgmt.msc run command
  3. In the Disk Management window, locate the partition that corresponds to the Ubuntu installation.

2. Remove GRUB Bootloader:

By default, Ubuntu uses the GRUB bootloader, which allows you to choose the operating system at startup. To remove the GRUB bootloader and restore the Windows bootloader, follow these steps:

  1. Restart your computer and boot into Windows 11.
  2. Right-click on the Windows logo and select Terminal (Admin) from the context menu.
  3. Then type the following command and press Enter

bcdedit /set {bootmgr} path \EFI\Microsoft\Boot\bootmgfw.efi
bcdedit set {bootmgr} path terminal command

  1. This command sets the Windows bootloader as the default option.
  2. Restart your computer once again to ensure that the changes take effect.

3. Using Windows Recovery Environment:

The Windows Recovery Environment (WinRE) is a specialized recovery environment in that provides various tools and options to troubleshoot and fix issues. It is useful for repairing startup problems and many more. To complete this method, you can follow these steps:

  1. Restart your computer and boot into the Windows Recovery Environment. 
  2. You can usually access this by pressing F8 or Esc key during startup. The key may vary depending on your computer manufacturer.
  3. In the Windows Recovery Environment, select Troubleshoot > Advanced options.

  7. Then restart your computer; it should boot directly into Windows 11 without showing the Ubuntu option.

4. Update Windows Boot Manager (Optional)

Although this step is not mandatory, updating the Windows Boot Manager to remove any residual traces of Ubuntu is recommended. To do this, follow these steps:

  1. Open the Terminal (Admin) like before.

  4. Then, execute the following command for each identifier by typing the following command and press Enter: bcdedit /delete {identifier}
    bcdedit delete {identifier} terminal command
