How to Install Windows 10 from USB via BIOS: A Step-by-Step Guide

posted on July 21, 2025

Installing Windows 10 from a USB via BIOS is a handy skill to have. First, you’ll create a bootable USB with Windows 10. Then, you’ll adjust your computer’s BIOS settings to boot from the USB. Finally, you’ll follow the installation prompts to get Windows 10 up and running. It’s straightforward once you know the steps.

How to Install Windows 10 from USB from BIOS

The following steps will guide you through installing Windows 10 using a USB drive and your computer’s BIOS settings.

Step 1: Create a Bootable USB

First, download the Windows 10 Media Creation Tool from Microsoft’s official site and use it to make a bootable USB.

Ensure your USB drive is at least 8GB, and remember, this process will erase all existing data on it. Keep important files backed up elsewhere.

Step 2: Insert the USB into Your Computer

Plug the bootable USB drive into an available USB port on your computer.

Using a USB 3.0 port can speed up the process if your device supports it, but any working port will do the job.

Step 3: Access BIOS/UEFI

Restart your computer and press the required key to enter BIOS/UEFI. This is usually F2, F12, Delete, or Esc, depending on your manufacturer.

Timing is key here. If you miss it, just restart and try again until you get the BIOS screen.

Step 4: Change Boot Order

In the BIOS menu, navigate to the Boot tab and set the USB drive as the primary boot device.

Be careful while making changes in the BIOS; only adjust what you need to. Wrong changes might affect your system.

Step 5: Save and Exit BIOS

Save the changes and exit the BIOS. Your computer will restart and boot from the USB.

Look for an option like "Save & Exit" or press the designated key (often F10) to save your settings.

Step 6: Install Windows 10

Follow the on-screen instructions to install Windows 10. Choose language, edition, and installation type when prompted.

The installation process will guide you through partitioning and installation options. Make sure to choose the right settings for your needs.

After completing these steps, your computer will begin installing Windows 10. The process includes copying files, expanding them, and setting up the system. Once done, you’ll be greeted with the Windows 10 setup screen, ready for personalization.

Tips for Installing Windows 10 from USB from BIOS

  • Double-check your USB drive for critical files before making it bootable.
  • Know your computer’s BIOS access key (F2, F12, Delete, etc.).
  • Ensure your computer is plugged in; installations can be power-intensive.
  • Keep your Windows 10 product key handy if prompted.
  • Have a backup plan in case anything goes wrong during installation.
