Installing or reinstalling Windows is often a necessary task for computer users. Whether your computer is running slow or has a virus, reinstalling Windows can help fix these issues. In this article, we will cover how to install Windows and provide step-by-step instructions and images to guide you through the process.

How to Install Windows

Before you begin the installation process, there are a few things you need to do first:

  • Back up important data
  • Download the correct ISO file for the version of Windows you want to install
  • Create a bootable USB drive or DVD using the ISO file
  • Make sure your computer is set to boot from the USB drive or DVD
  • Ensure you have a valid license key for the version of Windows you are installing

Step One: Boot from the USB Drive or DVD

Insert the bootable USB drive or DVD into your computer and turn it on. If your computer is set to boot from the USB drive or DVD, it will automatically start the installation process. If not, you will need to change the boot order in your computer’s BIOS.

To change the boot order, access the BIOS setup utility by pressing the appropriate key during startup. The key may vary depending on your computer’s manufacturer but is typically F2, F10, or F12. Once in the BIOS, navigate to the Boot Options menu and make sure the USB drive or DVD is selected as the primary boot device.

Save and exit the BIOS, and your computer will automatically restart and begin the Windows installation process.

Step Two: Choose Your Language, Time and Currency Format, and Keyboard or Input Method

When the Windows installation process starts, you will be prompted to choose your language, time and currency format, and keyboard or input method. Select the appropriate options and click “Next.”

Step Three: Install Windows

On the next screen, click “Install Now” to begin the Windows installation process.

Step Four: Enter Your License Key

On the next screen, you will be prompted to enter your license key. Enter the key and click “Next.”

Step Five: Accept the License Terms

Read through the license terms and if you agree to them, select “I accept the license terms” and click “Next.”

Step Six: Choose the Type of Installation

On the next screen, you will be prompted to choose the type of installation you want to perform. Select “Custom: Install Windows only (advanced)” to install a fresh copy of Windows and delete all the files on your computer.

Step Seven: Select the Drive Where You Want to Install Windows

Select the drive where you want to install Windows and click “Next.” If you have multiple drives, make sure you select the correct one to avoid losing important data.


Step Eight: Wait for Windows to Finish Installing

Windows will now begin installing. This process can take anywhere from 20 minutes to a few hours depending on your computer’s specifications. Once Windows has finished installing, your computer will automatically restart.


1. Can I install Windows without a license key?

No, you cannot install Windows without a valid license key. You can, however, use Windows for a limited time without activating it. This trial period lasts for 30 days, after which you will need to enter a valid license key to continue using Windows.

2. What should I do if my computer does not recognize my USB drive or DVD?

If your computer does not recognize your USB drive or DVD, first make sure the device is properly connected to your computer. Restart your computer and try again. If your computer still does not recognize the device, try using a different USB port or try using a different USB drive or DVD. If none of these solutions work, you may need to update your computer’s drivers or replace the USB port or DVD drive.
