How to Install Windows 10 on Windows 11: A Step-by-Step Guide

How to Install Windows 10 on Windows 11

If you need to install Windows 10 on a PC that currently has Windows 11, it’s doable and not overly complicated. You’ll need a USB drive, some time, and a bit of patience. Essentially, you’ll create a bootable USB drive with the Windows 10 installation files, adjust your computer’s boot settings, and then install Windows 10 in place of Windows 11.

How to Install Windows 10 on Windows 11

Follow these steps to replace your Windows 11 operating system with Windows 10. Make sure to back up any important files, as this process will erase everything on your hard drive.

Step 1: Create a Bootable USB Drive

Download the Windows 10 Media Creation Tool from Microsoft’s website, and use it to create a bootable USB drive.

Plug in a USB drive with at least 8GB of space. Run the Media Creation Tool, choose "Create installation media," and follow the prompts to download Windows 10 and set up the USB drive. This will take some time, so be patient.

Step 2: Back Up Your Files

Ensure you have backups of all important data before proceeding.

You can use an external hard drive, cloud storage, or both. Double-check that everything you need is safely backed up, as installing a new OS will wipe your current data.

Step 3: Change Boot Order in BIOS

Restart your computer and enter the BIOS or UEFI settings (usually by pressing a key like F2, F12, Delete, or Esc during startup), then set the USB drive as the primary boot device.

Look for a boot menu or boot order setting in the BIOS. Move the USB drive to the top of the list to ensure your PC boots from it first. Save your settings and restart.

Step 4: Boot from the USB Drive

When your computer restarts, it should boot from the USB drive.

This will bring up the Windows 10 installation screen. If it doesn’t, double-check the boot order settings in the BIOS.

Step 5: Install Windows 10

Follow the on-screen instructions to install Windows 10.

You’ll need to select your language preferences, agree to the license terms, and choose the custom install option. Select the partition where Windows 11 is currently installed to overwrite it with Windows 10. The installation process will take some time, and your PC will restart multiple times.

Step 6: Complete Setup

Once installation is complete, you’ll need to go through the initial Windows 10 setup.

This involves setting up a user account, choosing privacy settings, and connecting to the internet. Follow the prompts to complete these steps.

Once Windows 10 is installed and set up, you’ll find the familiar interface and features ready for use. Your PC will start fresh with a clean installation of Windows 10.
