Installing Windows 10 from a USB using BIOS can seem like a daunting task, but it’s simpler than you might think. First, you’ll need to create a bootable USB drive with the Windows 10 installation files. Then, restart your computer and enter the BIOS to set the USB as the primary boot device. Save the changes, exit BIOS, and follow the on-screen instructions to install Windows 10. This guide will walk you through each step, ensuring a smooth installation process.
How to Install Windows 10 from USB from BIOS
In this section, we’ll break down the process of installing Windows 10 from a USB through BIOS. Follow these steps to upgrade or set up a new installation of Windows 10 on your computer.
Step 1: Create a Bootable USB Drive
First, download the Windows 10 ISO file and use a tool like Rufus to make a bootable USB drive.
To do this, plug your USB into your computer, open Rufus, select the ISO file, and click “Start.” This will erase all data on the USB and create a bootable drive.
Step 2: Enter BIOS Setup
Restart your computer and press the designated key (often F2, F10, or Delete) to enter BIOS setup.
Each computer brand might have a different key, so if you’re unsure, a quick online search for your specific model will help.
Step 3: Set USB as First Boot Device
Once in BIOS, navigate to the Boot menu and set your USB drive as the first boot device.
Use the arrow keys to navigate, and follow the on-screen instructions to change the boot order. This ensures your computer boots from the USB.
Step 4: Save Changes and Exit
Save your changes in BIOS and exit to restart your computer.
Usually, pressing F10 saves your changes. Your computer will then reboot, initiating the Windows 10 installation process from the USB.
Step 5: Follow On-Screen Instructions
Once your computer boots from the USB, follow the on-screen instructions to install Windows 10.
You’ll be guided through selecting your language, time, and keyboard settings, followed by installing Windows.
After you’ve completed these steps, Windows 10 will begin the installation process. Your computer will restart a few times, but that’s completely normal. Once done, you’ll reach the setup screen where you can personalize settings and create a user account.
