If you’re looking to install or repair Windows 10, booting from a USB is a handy skill to have in your tech toolkit. First, create a bootable USB drive with Windows 10 installation files. Then, change your computer’s BIOS settings to boot from USB. Once set, restart your computer with the USB plugged in, and the Windows setup should start automatically. This method is especially useful for troubleshooting and clean installations.
How to Boot Windows 10 from USB
In this section, you’ll learn how to prepare and use a USB drive to boot Windows 10. These steps will guide you from preparing the USB drive to starting the Windows installation process.
Step 1: Create a Bootable USB Drive
To get started, you need to download the Windows 10 ISO file and use a tool like Rufus to make your USB drive bootable.
Rufus is a free utility that can quickly convert your USB into a bootable device. Simply download the Windows 10 ISO file from the Microsoft website, open Rufus, and follow the instructions to burn the ISO onto the USB drive. This process might take a few minutes depending on your USB’s speed and size.
Step 2: Insert the USB Drive into Your Computer
Once your USB is ready, plug it into a USB port on your computer.
Ensure the USB is securely connected to avoid interruptions. It’s a good idea to unplug other USB devices to prevent any confusion during the boot process. If you’re using a laptop, make sure it’s plugged into a power source to avoid any power-related issues.
Step 3: Access BIOS/UEFI Settings
Restart your computer and press the appropriate key (often F2, F12, or DEL) to enter the BIOS/UEFI setup.
The exact key to press varies by manufacturer, so watch for a prompt on the screen during startup. If you miss it, simply restart and try again. Once in the BIOS, you’ll need to navigate using your keyboard, as most BIOS setups don’t support mouse input.
Step 4: Change Boot Order to USB
In the BIOS menu, find the ‘Boot Order’ section and set USB as the first boot device.
Changing the boot order tells your computer to check the USB drive for boot instructions before the internal hard drive. Save your changes and exit the BIOS. Your computer will restart, and if the USB is properly set up, it will boot from it.
Step 5: Start the Windows 10 Setup
With the USB first in the boot order, the Windows setup should begin. Follow the on-screen instructions to install Windows 10.
The setup process will guide you through selecting language, time, and keyboard preferences. When prompted, choose ‘Install Now’ and follow the steps to complete the installation. Ensure you have your Windows 10 product key handy if it’s required.
After completing these steps, your computer will be ready to run the Windows 10 installation. You’ll have the option to clean install, upgrade, or repair your Windows system, depending on your needs.
Tips for Booting Windows 10 from USB
- Always back up important files before starting the installation process to prevent data loss.
- Ensure your USB drive has at least 8GB of storage to accommodate the Windows 10 ISO file.
- Keep your USB drive plugged in during the entire installation to avoid interruptions.
- If the computer doesn’t boot from the USB, double-check the boot order settings in the BIOS.

Frequently Asked Questions
What if my computer doesn’t recognize the USB?
Ensure the USB is securely connected and properly formatted. Check the BIOS settings to confirm the boot order is correctly configured.
