When installing a clean copy of Windows 10, usually you connect a USB media to the device to launch the "Windows Setup" wizard to continue with the installation process. However, if you have a computer with a Unified Extensible Firmware Interface (UEFI), instead of the legacy Basic Input/Output System (BIOS), it is crucial to use the appropriate media for the system firmware type.
On Windows 10, there are at least two methods to create a USB bootable media. You can use the Microsoft Media Creation Tool to download the files onto a removable storage with support for both firmware types (UEFI and legacy BIOS). Or you can use a third-party tool called "Rufus," which makes it easy to create a USB to install Windows with support for UEFI.
In this Windows 10 guide, we will walk you through the steps to create a USB flash drive that includes support for UEFI using the Microsoft Media Creation Tool and Rufus.
How to create Windows 10 UEFI boot media with Media Creation Tool
The best way to create a bootable USB media for an in-place upgrade or clean install of Windows 10 is to use the official Media Creation Tool available through the Microsoft support website.
To create a USB install media, connect a flash drive of at least 8GB of space, and then use these steps:
- Open Windows 10 download page.
Under the "Create Windows 10 installation media" section, click the Download tool now button to save the file on the device.

How to create Windows 10 UEFI boot media with Rufus
Alternatively, you can use Rufus, a free third-party tool that allows you to create an installation media with support for UEFI devices. You can use the tool to create a bootable media using an existing ISO file, or you can use the option to download the files from the Microsoft servers and then create the installation media.

After you complete the steps, Rufus will create a USB flash drive to install Windows 10 on a device using UEFI with a locally available image.

- Open Rufus download page.
Under the "Download" section, click the latest release (first link) of the tool to save the file onto your computer.

- Check the Quick format option.
- Check the Create extended label and icon files option.
- Click the Start button.
- Click the OK button.
- Click the Close button.
Once you complete the steps, the tool will run the script and download the Windows 10 ISO file. After the download, you can use that ISO file to create a bootable media to install Windows 10 on a UEFI device.
When you have the USB bootable media with support for UEFI systems, you can use it to start the "Windows Setup" wizard to perform a clean installation of Windows 10 or an in-place upgrade.
However, since the "UEFI:NTFS bootloader" does not include a digital signature for secure boot, you must temporarily disable secure boot on the motherboard firmware before you can boot into the setup wizard. Usually, you would complete this task from within the Unified Extensible Firmware Interface that you can access by hitting one of the function keys (F1, F2, F3, F10, or F12), the ESC, or Delete key as soon as you start the computer.
The only caveat is that these settings will be different per manufacturer and even by computer model. So make sure to check your device manufacturer's support website for more specific instructions. After the installation of Windows 10, you can enable the feature again.
