Before proceeding with the deletion of Windows 10, it is crucial to back up your important files and data. This ensures that you do not lose any valuable information during the process. Create a backup of your files on an external storage device or use cloud storage services for added security.

Step 2: Create a Windows 11 Installation Media

To delete Windows 10 and install Windows 11, you will need a Windows 11 installation media. Follow these steps to create one:

Creating a Windows 11 installation media ensures that you have a reliable source to install the new operating system without relying on the existing Windows 10 installation.
