How to Uninstall Ubuntu from Windows 11: A Step-by-Step Guide

Uninstalling Ubuntu from Windows 11 involves a few simple steps that primarily focus on removing the Ubuntu partition and restoring the Windows boot loader. By following these steps, you can ensure that your system is back to its original state, running only Windows 11 without any trace of Ubuntu.

How to Uninstall Ubuntu from Windows 11

In this tutorial, you’ll learn how to safely remove Ubuntu from a dual-boot setup with Windows 11. We’ll go through deleting the Ubuntu partition, fixing the Windows boot loader, and reclaiming the freed-up space. Once completed, your computer will boot directly into Windows 11 without showing the GRUB boot menu.

Step 1: Backup Important Data

Before proceeding, make sure to back up any important data from both Windows and Ubuntu partitions.

This step is crucial because data loss can occur when modifying partitions. Use an external drive or cloud service to save your files.

Step 2: Access Disk Management

Press Win + X and select "Disk Management" to open the Disk Management utility.

Disk Management is a built-in Windows tool that helps you manage disk partitions and volumes. It will show all the drives and partitions on your computer.

Step 3: Identify the Ubuntu Partition

In Disk Management, identify the partition where Ubuntu is installed. Typically, it will be an Ext4 file system.

You can often recognize the Ubuntu partition by the absence of a drive letter and its size. Make sure you don’t accidentally select a different partition.

Step 4: Delete the Ubuntu Partition

Right-click on the Ubuntu partition and choose "Delete Volume" to remove it.

This will delete the partition and turn it into unallocated space. Don’t worry, you will reclaim this space later.

Step 5: Extend the Windows Partition

Now, right-click on the Windows partition (usually C:) and select "Extend Volume" to use the unallocated space.

This action will allow Windows to utilize the space previously occupied by Ubuntu, effectively enlarging your Windows partition.

Step 6: Fix the Windows Boot Loader

Insert a Windows 11 installation media, boot from it, and select "Repair your computer." Then choose "Troubleshoot" > "Advanced options" > "Command Prompt."

This step is required to replace the GRUB bootloader with the Windows bootloader, ensuring your system boots directly into Windows.

Step 7: Execute Bootrec Commands

In Command Prompt, type the following commands one by one and press Enter after each:

bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd

These commands will repair and rebuild the Windows boot configuration, making sure the system can boot properly.

After completing these steps, your computer will boot directly into Windows 11 without any option to boot into Ubuntu.
