  • To create a Windows 11 25H2 USB bootable media, connect a USB flash drive to your PC, open Rufus, select the ISO file, use the default settings, click “Start,” and customize the settings, including creating a media for unsupported hardware.
  • To use “Ventoy,” install the app on a USB flash drive and then drop the Windows 11 25H2 ISO file into the storage.
  • To use “Command Prompt,” download the Windows 11 2025 Update ISO file, and use the “diskpart” tool to clear, create a partition, and copy the installation files to the USB media.
  • To use the “Media Creation Tool,” launch the application, customize the settings, select “USB flash drive,” choose the bootable media, click “Next,” and then “Finish.” 

If you want to install Windows 11 25H2 (2025 Update) on a computer that meets the hardware requirements, you’ll need to create a bootable USB media. In this guide, I will outline the various methods available to complete this task. Although there are multiple ways to upgrade to a new version of Windows 11, starting a device with a USB bootable media is the best method to resolve issues and ensure a fresh installation. It’s also the only way to install Windows 11 25H2 on a new, empty hard drive.

When you have to create a bootable USB flash drive to set up a new installation of Windows 11 25H2, you can use the Media Creation Tool, which is the official tool. However, you can also use third-party tools, such as Rufus and Ventoy. You can even use Command Prompt to create offline installation media manually.

In this guide, I will teach you multiple ways to create a USB bootable media to perform an in-place or clean install of the Windows 11 2025 Update. Although you can use virtually any USB flash drive, ensure it has at least 8GB of space. Additionally, before proceeding, back up any data on the flash drive, as this process will format the storage, erasing its contents.

Important: Microsoft only makes available the installation files after the feature update becomes available to everyone, not before. If you attempt to use the Media Creation Tool before version 25H2 is officially released, you’ll create a USB installer for version 24H2 instead. Also, the option to download the ISO file using the Rufus tool will be available once the new version of the operating system is released.

    Quick note: At the time of this writing, the ISO file is only available through the Windows Insider Program. Once version 25H2 becomes officially available, you’ll be able to use the Rufus download option.
