Hello Nouasria,

Thanks for reaching out here in the Microsoft Answers Community.

You cannot install Windows on external storage, because the system is not designed for such use.

The "Win to USB" tool you mentioned is not developed by Microsoft, and is therefore not supported.

If you still need to use Windows in this way, please contact the developers of that tool for further assistance.

Thanks for your patience and understanding.
