Reinstalling Windows 10 from BIOS might seem like a daunting task, but it’s actually quite straightforward. You’ll need a bootable USB drive with Windows 10 on it, and you’ll access BIOS to boot from that USB. Follow these steps to get a fresh installation of Windows 10 on your computer.
How to Reinstall Windows 10 from BIOS
Reinstalling Windows 10 from BIOS allows you to start fresh, erasing all data and settings on your device. Follow these steps to achieve a clean installation.
Step 1: Create a Bootable USB Drive
You’ll need a USB drive with at least 8GB of storage. Download the Windows 10 ISO file from Microsoft’s website and use the Media Creation Tool to make the USB drive bootable.
Once you have the bootable USB drive, keep it safe. This drive is essential for reinstalling Windows and having it ready beforehand makes the process smoother.
Step 2: Insert the Bootable USB Drive
Plug the USB drive into your computer’s USB port. Make sure the computer is off when you do this.
Connecting the USB drive before starting up your computer will allow the BIOS to recognize it as a boot option.
Step 3: Access BIOS Setup
Turn on your computer and immediately press the BIOS key—usually F2, F10, Delete, or Esc, depending on your computer model.
Pay attention as you power up; the correct key is often displayed briefly on the screen. If you miss it, just restart and try again.
Step 4: Change Boot Order
In BIOS, navigate to the Boot menu and set the USB drive as the primary boot device. Save changes and exit BIOS.
Changing the boot order tells your computer to load the operating system from the USB drive first, rather than the internal hard drive.
Step 5: Start Windows Installation
Your computer will restart and boot from the USB drive. Follow the on-screen instructions to install Windows 10. Choose "Custom Install" for a clean installation.
The setup will prompt you through language, time, and keyboard settings, and then you’ll be asked where to install Windows. Select the appropriate drive, usually the largest one.
Step 6: Complete the Installation
After the setup completes, your computer will restart a few times. Follow the on-screen prompts to finalize the setup.
You may need to enter some information like your Microsoft account or preferred settings. Once done, you’ll have a fresh installation of Windows 10.
After completing these steps, your computer will have a clean version of Windows 10 installed. You can now reinstall your applications and restore files from backups if needed.
