How to Install Windows 10 on a Windows 11 Computer

Installing Windows 10 on a Windows 11 computer is a straightforward process. You will need a Windows 10 installation media, your computer, and a bit of patience. Essentially, you’ll back up your data, create a bootable USB drive with Windows 10, and follow the installation instructions. Let’s dive into the nitty-gritty details!

How to Install Windows 10 on a Windows 11 Computer

In this section, we’ll walk through the process of installing Windows 10 on a computer that currently runs Windows 11. Each step is designed to make sure you know exactly what to do and why it’s important.

Step 1: Back Up Your Data

Before starting, back up all important data on an external drive or cloud service.

Backing up ensures that you won’t lose any important files during the installation process. Data loss can be devastating, so make sure everything is safely stored elsewhere.

Step 2: Create a Bootable USB Drive

Download the Windows 10 ISO from Microsoft’s website and use a tool like Rufus to create a bootable USB drive.

You’ll need at least an 8GB USB drive. The tool will format the drive and copy the necessary files, making it ready for installation.

Step 3: Change Boot Order in BIOS

Restart your computer and enter the BIOS setup by pressing the appropriate key (often F2, F12, or Del) during startup. Change the boot order to prioritize the USB drive.

This step ensures that your computer boots from the USB drive instead of the hard drive, allowing the installation process to begin.

Step 4: Start the Installation Process

Insert the bootable USB drive into your computer and restart it. Follow the on-screen instructions to install Windows 10.

The installation wizard will guide you through the steps, including selecting your language preferences and agreeing to the terms of service.

Step 5: Choose Custom Installation

When prompted, choose the "Custom: Install Windows only (advanced)" option.

This option allows you to perform a clean installation, which is ideal if you want to completely replace Windows 11 with Windows 10.

Step 6: Select Partition for Installation

Select the partition where Windows 11 is currently installed and format it. Then, select it as the installation location.

Formatting the partition will erase Windows 11, making room for a fresh installation of Windows 10.

Step 7: Complete the Installation

Follow the remaining on-screen instructions to complete the installation. Your computer will restart several times.

Once the installation is complete, you’ll be guided through the initial setup of Windows 10, including creating a user account and setting preferences.

After completing these steps, you’ll have successfully installed Windows 10 on your computer. Your computer will reboot into Windows 10, and you can start reinstalling your applications and restoring your backed-up data.

Tips for Installing Windows 10 on a Windows 11 Computer

  • Check Compatibility: Make sure your hardware is compatible with Windows 10. Most Windows 11-compatible systems will be, but it’s good to double-check.
  • Keep Drivers Handy: Download the necessary drivers for your hardware from the manufacturer’s website beforehand, as you might need to install them manually.
