Booting Windows from a USB is like giving your computer a fresh start using a portable device. It can be super handy if you’re installing a new version of Windows, fixing a broken system, or just want a clean slate. In a nutshell, you’ll need to create a bootable USB drive with Windows on it, adjust some settings in your computer’s BIOS or UEFI, and then let your computer load Windows directly from the USB instead of its regular hard drive.
How to Boot Windows from USB
In this section, we’ll walk through the steps to help you boot Windows from a USB. By the end, your computer will know to look for the operating system on the USB first.
Step 1: Get a USB Drive
Make sure you have a USB drive with at least 8GB of space.
You’ll be using this USB to store the Windows installation files, so it needs to be big enough. Keep in mind that this process will erase all existing data on the USB drive.
Step 2: Download Windows Installation Tool
Download the Windows Media Creation Tool from Microsoft’s official website.
This tool will help you download the Windows files and prepare the USB drive. It’s user-friendly and guides you through each step, making the process easier for beginners.
Step 3: Create a Bootable USB
Run the media creation tool and choose the option to create installation media. Follow the steps to complete the process.
The tool will format your USB drive and copy all the necessary Windows files onto it. Patience is key here, as this might take a while depending on your internet speed and computer performance.
Step 4: Adjust BIOS/UEFI Settings
Restart your computer and enter the BIOS or UEFI settings by pressing a specific key during boot-up (often F2, F12, or Delete).
Inside the BIOS/UEFI, you’ll need to change the boot order so that USB devices are checked before the hard drive. This step ensures that your computer will try to load Windows from the USB first.
Step 5: Boot from the USB
Save the changes in BIOS/UEFI and restart your computer with the USB plugged in.
Your computer will now boot from the USB, and you should see the Windows Setup screen. From here, you can proceed with installing or repairing Windows.
After completing these steps, your computer will start using Windows from the USB drive. This can be particularly useful when you’re trying to recover a system or want to install Windows on a new machine.
