Installing Windows 10 on a new hard drive might sound a bit intimidating, but it’s actually straightforward. You just need to make a bootable USB, plug it into your computer, and follow the on-screen instructions. By the end of this guide, you’ll have a fresh Windows 10 installation ready to go.
How to Install Windows 10 on a New Hard Drive
In the following steps, we’ll walk through creating a bootable USB drive to installing Windows 10 on a brand new hard drive. It’s a good idea to have your Windows 10 product key and a second working computer handy before starting.
Step 1: Create a bootable USB drive
You’ll need the Windows 10 ISO file and a USB drive with at least 8GB of space.
To do this, download the Windows Media Creation Tool from the Microsoft website, run it, and choose “Create installation media.” Follow the prompts to put the Windows 10 ISO on your USB drive.
Step 2: Insert the USB drive into your new computer
Shut down your computer and insert the bootable USB drive.
When you start it up again, you’ll need to enter the BIOS or UEFI settings (usually by pressing a key like F2, F12, Delete, or Esc) and change the boot order so the USB is first.
Step 3: Start the installation process
With the USB drive set up as the first boot device, restart your computer.
You should see the Windows logo and the installation process will begin. Choose your language, time, and keyboard preferences, then click “Next” and “Install now.”
Step 4: Enter your product key
You’ll be prompted to enter your Windows 10 product key.
If you don’t have it handy, you can skip this step and enter it later.
Step 5: Choose the custom installation option
When asked what type of installation you want, select “Custom: Install Windows only (advanced).”
This will let you install Windows 10 on your new hard drive. You’ll see a screen with a list of your drives and partitions.
Step 6: Select the new hard drive
Pick the new hard drive from the list.
If the drive hasn’t been formatted yet, you may need to do so by selecting it and clicking “New,” then “Apply.” This will prepare the drive for the installation.
Step 7: Complete the installation
Follow the remaining on-screen instructions to complete the installation.
Your computer will restart several times during this process. Once it’s done, you’ll be taken through the initial setup of Windows 10.
After you complete these steps, your computer will restart and boot into the new Windows 10 installation. You’ll need to go through the initial setup, including setting up a user account and adjusting your settings.
