Introduction

Dual booting Windows 7 and Windows 10 can be a practical solution for users who require access to both operating systems. However, there may come a time when you no longer need Windows 7 and want to remove it from your system to free up space and streamline your boot menu. This guide will provide step-by-step instructions on how to remove Windows 7 from a Windows 10 dual boot setup safely and effectively.

Step-by-Step Guide to Removing Windows 7 from Windows 10 Dual Boot

1. Back Up Your Data

Before proceeding with any changes, ensure you have backed up all important data from both Windows 7 and Windows 10. This step is crucial as the removal process could potentially result in data loss.

3. Navigate to the Boot Tab

In the System Configuration window, select the Boot tab. You should see a list of operating systems currently installed on your system.

4. Select the Windows 7 Entry and Delete It

Highlight the Windows 7 entry and click the Delete button. Confirm your selection when prompted.

5. Check the Timeout and Default Operating System

Ensure that the Timeout value is set to a low number, such as 5 seconds, to minimize the time spent on the boot menu. You can also select Windows 10 as the Default operating system.

6. Click Apply and Restart

Click the Apply button to save your changes and the OK button to close the window. Restart your computer to complete the process.
