Previously, I showed you how to install Windows 10 using a bootable USB stick. This method is suitable for devices which boot using the legacy BIOS mode. If you need a UEFI bootable USB stick, the earlier-mentioned method will not work. In this article, we will see how to create a bootable UEFI USB drive containing Windows 10 Setup.

It is a good idea to use the Rufus tool to prepare the bootable UEFI Windows 10 USB drive. Rufus is free and works without any issues. Also, it is a portable app so it does not require itself to be installed. Here are the step-by-step instructions:

  1. Download the latest version of Rufus from HERE.
  2. You need a USB drive with at least 4 GB available. All data on this drive will be erased, so it is a good idea to backup everything from this USB drive before proceeding.
  3. Run the Rufus utility and pick your USB drive under the Device section.
  4. Select the partition scheme for UEFI computers with MBR. If your PC has a GPT partition scheme (GUID Partition Table), then pick the appropriate option from the combobox.
  5. Click on the CD/DVD drive icon to browse to the Windows 10 ISO image file. Select the Windows 10 ISO image file – 32-bit or 64-bit – whichever you downloaded.
    If you do not have the ISO image, here’s how you can build your own: Get ISO image for Windows 10 build 9860 for a clean install.
Windows 10 UEFI USB

After you click the Start button in Rufus, it will create a bootable UEFI USB stick with Windows 10. That’s it. You are done.
