  • To install Windows 11 24H2 from an ISO file without USB, right-click the ISO file and choose “Mount,” open the virtual drive, and double-click “Setup.exe” to start the upgrade or clean install process.

You can always mount the ISO file to File Explorer and launch the setup process to upgrade to Windows 11 24H2 without the extra USB bootable media steps. This works for devices already running Windows 11 or any supported version of Windows 10.

Although it’s possible to use a USB flash drive to perform a clean installation or in-place upgrade, if you don’t have a USB flash drive (or the one you have isn’t working),  you can also mount the Windows 11 24H2 ISO file to launch the setup without any physical media.

In this guide, I will teach you how to perform a Windows 11 24H2 upgrade or clean installation without a bootable USB or Media Creation Tool.

Important: This process will delete everything on your device. It’s recommended that you make a full backup of your computer before proceeding. You’ve been warned. Windows 11 24H2 is expected to be released for existing devices sometime in September or October. These instructions are meant for when the feature update is available. It’s important to note that on June 18, the new version will only be available for the new Copilot+ PC, not existing devices. You can upgrade early to this new feature update with these instructions.
