Although you can install Windows 11 in multiple ways, if you plan to start from scratch, you usually use a bootable USB flash drive to proceed with the setup. However, you must manually create one since you cannot officially purchase a physical media from the Microsoft Store.

On Windows 11, you have at least two tools to download the installation files onto a USB flash drive and make it bootable. You can use the official Media Creation Tool to download the files to removable storage. You can also use Rufus, a third-party tool that makes creating a flash drive to install the operating system on a compatible or incompatible device easy.

In this how-to guide, I'll explain how to create a USB flash drive with support for Unified Extensible Firmware Interface (UEFI) firmware using the Microsoft Media Creation Tool and Rufus.

  1. Open Windows 11 download page.
  2. Click the Download now button to save the file on the device under the "Create Windows 11 Installation Media" section.

Alternatively, you can also use Rufus, a free non-Microsoft tool that allows you to create installation media on virtually any hardware and software configuration. The utility provides two methods for creating the installation media using an existing ISO file or directly downloading the file from the Microsoft servers.
