Step 1: Back Up Your Data
Make sure to back up all your important files and documents before proceeding.
Backing up your data is crucial because the process will erase everything on your computer. Use an external hard drive, cloud storage, or any other backup method you prefer.
Step 2: Create Windows 10 Installation Media
Download the Windows 10 Media Creation Tool from Microsoft’s website and use it to create a bootable USB drive.
This tool will help you install Windows 10 on your PC. Once downloaded, follow the instructions to create a bootable USB. Make sure your USB drive has at least 8GB of space.
Step 3: Change Boot Order in BIOS
Restart your computer and enter the BIOS settings to change the boot order to the USB drive.
Typically, you can access BIOS by pressing a key like F2, F12, or Delete during startup. Navigate to the boot settings and set the USB drive as the primary boot option.
Step 4: Boot from USB Drive
Insert the USB drive into your computer and restart it. It should boot from the USB drive.
If done correctly, your computer will start from the USB drive instead of the hard drive, and you’ll see the Windows 10 setup screen.
Step 5: Install Windows 10
Follow the on-screen instructions to install Windows 10. Choose ‘Custom Install’ and select the drive where Windows 11 is installed.
The installation process will format the drive, removing Windows 11 and replacing it with Windows 10. This step might take some time, so be patient.
Step 6: Complete the Installation
Once the installation is complete, follow the setup instructions to configure your Windows 10 environment.
After the installation, you’ll go through the initial setup screens to personalize your Windows 10 settings, create a user account, and adjust privacy settings.
