How Do I Install Windows 11 Without Paying?

1. Check Your System Compatibility

Before you begin, ensure your computer meets the minimum system requirements for Windows 11.

Processor: 1 GHz or faster with 2 or more cores on a compatible 64-bit processor or System on a Chip (SoC).
RAM: 4 GB
Storage: 64 GB or larger storage device
System Firmware: UEFI, Secure Boot capable
TPM: Trusted Platform Module (TPM) version 2.0
Graphics Card: Compatible with DirectX 12 or later with WDDM 2.0 driver
Display: High definition (720p) display that is greater than 9” diagonally, 8 bits per color channel

You can download and run the PC Health Check app from Microsoft’s website to quickly determine if your system is compatible.

2. Back Up Your Important Files

Before making any significant changes to your system, it’s crucial to back up your important files. This includes documents, photos, videos, and any other data you don’t want to lose.

Copy your files to an external hard drive.
Use a cloud storage service like OneDrive, Google Drive, or Dropbox.
Create a system image backup for a complete recovery option.

3. Download the Windows 11 ISO File

The ISO file is a digital image of the Windows 11 installation media. You can download it directly from Microsoft’s website.

Go to the Microsoft Windows 11 download page.
Under “Download Windows 11 Disk Image (ISO),” select “Windows 11” from the dropdown menu and click “Download.”
Choose your product language and click “Confirm.”
Click the 64-bit download button to download the ISO file.

4. Create Bootable Media

To install Windows 11 from the ISO file, you need to create bootable media, such as a USB drive or DVD.

Download and install Rufus, a free tool for creating bootable USB drives (https://rufus.ie/en/).
Insert a USB drive (at least 8 GB) into your computer.
Open Rufus.
Select your USB drive from the “Device” dropdown menu.
Click “Select” and choose the Windows 11 ISO file you downloaded.
Ensure the “Boot selection” is set to “Disk or ISO image.”
Leave the other settings at their defaults (GPT partition scheme for UEFI).
Click “Start” to begin creating the bootable USB drive.
Wait for the process to complete. This may take a few minutes.

5. Boot From the USB Drive

To start the Windows 11 installation, you need to boot your computer from the USB drive you created.

Restart your computer.
As your computer starts, press the key to enter the BIOS/UEFI setup. This key varies depending on your manufacturer (e.g., F2, Delete, Esc, F12).
In the BIOS/UEFI setup, go to the “Boot” menu.
Change the boot order to prioritize the USB drive.
Save the changes and exit the BIOS/UEFI setup.
Your computer will now boot from the USB drive.

6. Install Windows 11

Follow the on-screen instructions to install Windows 11.

Select your language, time, and keyboard preferences.
Click “Install now.”
If you have a product key, enter it. If you’re upgrading from a previous version of Windows, you may be able to skip this step (Windows should automatically activate later).
Select “I don’t have a product key” if you are reinstalling.
Choose the edition of Windows 11 you want to install (e.g., Home, Pro).
Accept the license terms.
Choose “Custom: Install Windows only (advanced)” to perform a clean installation.
Select the partition where you want to install Windows 11. If you’re upgrading, you can choose to install it on the existing Windows partition. If you’re doing a clean install, you may need to format the partition first.
Wait for the installation to complete. Your computer will restart several times during this process.
Follow the on-screen prompts to set up your user account, privacy settings, and other preferences.

Tips For A Smooth Installation

Ensure your computer is connected to a stable power source during the installation process.
Disconnect any unnecessary peripherals, such as printers or external drives, to avoid potential conflicts.
If you encounter any errors, consult the Windows 11 documentation or online forums for troubleshooting tips.
Make sure your BIOS is updated to the latest version.
If you are upgrading from Windows 10, ensure it is activated before starting the process.
