How to Install Windows 11 on New PC Without Operating System

Installing Windows 11 on a new PC without an operating system might sound like a daunting task, but fear not! It’s actually quite straightforward. Essentially, you’ll need to create a Windows 11 installation media on a separate device, change your new PC’s boot order to boot from this media, and then simply follow the on-screen instructions to install Windows 11. With a bit of patience and the right preparation, you’ll have your new PC up and running in no time.

Step by Step Tutorial on How to Install Windows 11 on New PC Without Operating System

Before we dive into the steps, let’s clarify what we’re aiming to achieve. By the end of this process, you will have successfully installed Windows 11 on your new PC, which originally had no operating system. You’ll be able to boot up your PC and start personalizing your new Windows environment.

Step 1: Create a Windows 11 Installation Media

First things first, you need to create a bootable installation media for Windows 11.

To do this, you’ll need another computer with internet access and a USB drive with at least 8GB of space. Head over to Microsoft’s official website and download the Media Creation Tool. Once downloaded, run the tool and follow the prompts to create your installation media.

Step 2: Insert Installation Media into New PC

With your bootable USB drive in hand, it’s time to plug it into your new PC.

Make sure your PC is completely turned off before you insert the USB drive into an available USB port. This step is crucial because your PC will need to boot from this USB drive to start the installation process.

Step 3: Enter the PC’s BIOS or UEFI Settings

Now, you need to enter the PC’s BIOS or UEFI settings to change the boot order.

Turn on your PC and press the necessary key to enter the BIOS or UEFI settings. This key varies depending on the manufacturer but is typically one of the function keys (like F2, F10, or F12), the Esc key, or the Delete key. You should see a message indicating which key to press when you first power on your PC.

Step 4: Change Boot Order to Boot from USB

Within the BIOS or UEFI settings, navigate to the boot order or boot priority section.

You’ll want to arrange the boot order so that the USB drive is the first option. This will allow your PC to boot from the installation media instead of looking for an operating system on its internal drives (which it won’t find because there isn’t one yet).

Step 5: Save Changes and Reboot

After setting the USB drive as the primary boot device, save your changes and exit the BIOS or UEFI settings.

Your PC will restart, and if everything was done correctly, it should boot from the USB drive and launch the Windows 11 installation process.

Step 6: Follow On-Screen Instructions to Install Windows 11

Once the installation starts, simply follow the on-screen instructions.

You’ll be asked to select your language, time, and currency format, and keyboard or input method. Then, click ‘Install Now’ and enter your Windows 11 product key when prompted. If you don’t have a product key, you can choose to enter it later. Follow the prompts to choose the installation type, partition your hard drive if necessary, and begin the installation.

After completing the installation, your PC will reboot again. Once it’s back up, you’ll go through the initial setup process, creating a user account, and adjusting settings to your preference.

What Happens After Installation

Once the installation is complete and your PC reboots, you’ll be greeted with the initial setup screen for Windows 11. Here, you’ll configure your preferences, connect to the internet, and sign in with a Microsoft account. After these steps, you’ll land on the Windows 11 desktop, ready to explore and enjoy your new operating system!
