If you just bought a new PC and it doesn’t have an operating system, don’t worry! Installing Windows 10 is a straightforward process. You’ll need a USB drive with at least 8GB of storage, an internet connection, and a valid Windows 10 license. First, you’ll create a bootable USB drive with Windows 10, then you’ll start your PC from that drive and follow the on-screen instructions to complete the installation.
How to Install Windows 10 on New PC Without Operating System
This step-by-step guide will help you install Windows 10 on your new PC, starting from creating a bootable USB, all the way to setting up Windows for the first time.
Step 1: Create a Bootable USB Drive
Download Microsoft’s Media Creation Tool and use it to make a bootable USB drive with Windows 10.
To create a bootable USB drive, visit the official Microsoft website, download the Media Creation Tool, and run it. Follow the prompts to download Windows 10 and prepare your USB drive. Make sure your USB drive has at least 8GB of space and is empty, as this process will erase all data on it.
Step 2: Insert the USB Drive into Your New PC
Plug the bootable USB drive into your new PC’s USB port.
With the USB drive prepared, insert it into an available USB port on your new PC. Ensure your PC is turned off when you do this to avoid any issues during the next steps.
Step 3: Access the Boot Menu
Turn on your PC and access the boot menu by pressing the designated key (usually F12, ESC, or DEL).
When you power on your PC, you’ll need to quickly press the boot menu key specific to your motherboard manufacturer. This will vary, so you might need to check your manual or try different keys like F12, ESC, or DEL.
Step 4: Boot from the USB Drive
Select the USB drive from the boot menu to start the Windows 10 installation process.
Once in the boot menu, use the arrow keys to select your USB drive and hit Enter. Your PC will then load the Windows 10 installation setup from the USB drive.
Step 5: Follow the On-Screen Instructions
Complete the Windows 10 installation by following the on-screen prompts.
The installation wizard will guide you through selecting your language, time, and keyboard settings, followed by entering your product key and choosing the installation type. Opt for a Custom installation for a clean install on a new PC.
You’ll need to select the drive where you want to install Windows. For a new PC, there should only be one option. The installation will now begin, and your PC will restart several times during the process.
After completing these steps, your PC will reboot into Windows 10. You’ll be prompted to set up your user account, connect to a network, and adjust privacy settings.
