WinSetupFromUSB is a third-party program that you can use to create a bootable USB drive containing the Windows 11 installer, as well as installation media for other older versions of Windows.

Instructions: Launch the software, select the target USB drive from the list, check the box for Use FBinst to automatically format, check the Windows Vista/7/8/10/11 option and select your local Windows 11 ISO file, then click “Go” to begin writing the files to the USB drive.

Its advantages include: support for multi-boot USB drives containing multiple system installers, automatic USB formatting optimized for booting, and full compatibility with both BIOS and UEFI boot modes.

Its disadvantages include: a cluttered and complex interface filled with many unfamiliar advanced settings; slow processing speeds when creating multi-boot media; and redundant professional features that may confuse average users.

Notes

  • Carefully verify the selected USB device to avoid accidentally formatting your local hard drive.
  • Do not remove the USB flash drive while the program is running, or the bootable media may be damaged.
  • Close all software accessing the target USB drive during the writing process to prevent file write failures.

This allows you to create a portable USB drive containing the full Windows 11 installer. It is suitable for technicians who need to maintain multiple versions of Windows, users who require a multi-boot USB drive, and situations where you need to reinstall Windows 11 offline on various computers.
