Step 1: Gather Your Tools
First, you need a USB drive with at least 16GB of space, a Windows ISO file, and the Windows USB/DVD Download Tool.
Ensure your USB drive is empty because this process will erase everything on it. The Windows ISO file can be downloaded from Microsoft’s website. The download tool will help you transfer the Windows files onto the USB.

This tool is essential because it will create a bootable Windows installation on your USB drive. Follow the installation prompts, which are as simple as clicking “Next” a few times.
Step 3: Run the Tool
Open the Windows USB/DVD Download Tool and select the Windows ISO file.
Once opened, you’ll be asked to choose the ISO file you downloaded earlier. This file contains all the necessary Windows installation data.
Step 4: Choose the USB Drive
Select “USB device” as the media type and choose your USB drive from the list.
Ensure you’ve picked the right drive. Double-check to avoid accidentally erasing the wrong drive. Click “Begin copying.”
Step 5: Create the Bootable USB
The tool will now copy the Windows files and make the USB drive bootable.
This process might take a little while, so be patient. Once completed, your USB drive will be ready to use as a portable Windows operating system.
After completing these steps, your USB drive will contain a fully functional Windows system. You can plug it into any computer and boot from the USB, giving you access to Windows wherever you go!
