How to Remove Dual Boot Ubuntu from Windows 10: A Step-by-Step Guide

If you’re looking to remove a dual boot of Ubuntu from your Windows 10 machine, the process is straightforward. First, you’ll need to delete the Ubuntu partitions. Then, you’ll fix the Windows boot loader, so your computer boots directly into Windows. Finally, clean up the boot entry for Ubuntu in the Windows Boot Manager.

How to Remove Dual Boot Ubuntu from Windows 10

In this step-by-step tutorial, you’ll learn how to remove Ubuntu from your dual-boot system while keeping Windows 10 intact. This involves deleting partitions, fixing the boot loader, and cleaning up boot entries.

Step 1: Back-Up Your Data

Always back up important files before making changes to your system.

Even though these steps are generally safe, mistakes can happen. Backing up ensures you don’t lose anything important.

Step 2: Delete Ubuntu Partitions

Open Disk Management by right-clicking on the Start Menu and selecting "Disk Management." Identify the Ubuntu partitions, usually "ext4" or "swap," right-click on them, and choose "Delete Volume."

Deleting these partitions will free up space on your hard drive. It is crucial to identify the correct partitions to avoid deleting Windows partitions.

Step 3: Extend Your Windows Partition

Right-click on your Windows partition in Disk Management and choose "Extend Volume" to reclaim the unallocated space.

This step ensures that the space previously occupied by Ubuntu is now part of your Windows partition, maximizing your storage.

Step 4: Fix the Windows Boot Loader

Insert your Windows installation media and boot from it. Choose "Repair your computer," go to "Troubleshoot," and then to "Command Prompt." Type bootrec /fixmbr and press Enter.

This command writes a new master boot record to the hard drive, ensuring that your system boots directly into Windows.

Step 5: Clean up Boot Entry

Open Command Prompt with administrative privileges and type bcdedit /delete {identifier} where {identifier} is the UUID of the Ubuntu entry.

This step removes the Ubuntu entry from the Windows Boot Manager, making the boot process cleaner and faster.

After completing these steps, your computer will boot directly into Windows 10 without showing the dual boot menu.
