Installing Windows 10 on a new or old PC can be a daunting task, especially if you're not tech-savvy. However, with the right steps and preparation, you can fresh install Windows 10 like a pro. In this comprehensive guide, we'll walk you through the process of installing Windows 10 from scratch, covering every detail you need to know.
Pre-Installation Checklist
Before you begin the installation process, make sure you have the following:
- A valid Windows 10 license key (if you don't have one, you can purchase it from the Microsoft Store)
- A USB flash drive with at least 8GB of free space (if you're using a USB drive to install Windows 10)
- The latest version of the Windows 10 installation media (you can download it from Microsoft's website)
- Your PC's BIOS or UEFI firmware settings configured to boot from the installation media (we'll cover this in the next section)
- A clean and organized workspace to prevent distractions during the installation process
Preparing Your PC for Installation
To ensure a smooth installation process, you need to prepare your PC's BIOS or UEFI firmware settings. This involves configuring your PC to boot from the installation media. Here's how to do it:

To access your PC's BIOS or UEFI settings, follow these steps:
- Restart your PC and immediately start pressing the F2, F12, or Del key (depending on your PC's manufacturer) to enter the BIOS or UEFI settings
- Use the arrow keys to navigate to the "Boot" or "Boot Order" section and set the installation media (USB drive or CD/DVD) as the first boot device
- Save and exit the BIOS or UEFI settings
Creating a Bootable Installation Media
If you don't have a USB drive or CD/DVD with the Windows 10 installation media, you need to create one. Here's how:
To create a bootable USB drive, follow these steps:

- Download the Windows 10 installation media from Microsoft's website
- Use a tool like Rufus or Etcher to create a bootable USB drive from the downloaded installation media
- Make sure the USB drive is at least 8GB in size and has no important files on it
Installing Windows 10
Now that you have your PC prepared and the installation media created, it's time to install Windows 10. Follow these steps:
Insert the installation media into your PC and restart it. Your PC should boot from the installation media. If it doesn't, make sure the BIOS or UEFI settings are configured correctly. Once the installation process starts, follow these steps:
- Click on the "Install Now" button to begin the installation process
- Enter your Windows 10 license key and click "Next"

Installing Drivers and Updates
After installing Windows 10, you need to install drivers and updates to ensure your PC is up-to-date and running smoothly. Here's how:
During the installation process, you'll be prompted to install drivers and updates. Click on "Check for updates" to ensure your PC has the latest drivers and updates. If you're installing drivers manually, you can do so by:
