How to create a bootable Windows 7, 8, 10, 11 installer USB on macOS

Run in Terminal:

  1. brew install wimlib - run, if wimlib is not installed yet (required for splitting large files)
  2. To identify target USB device, run: diskutil list
  3. Format USB drive: diskutil eraseDisk MS-DOS "$WIN_USB_NAME" MBR /dev/$DISK where $WIN_USB_NAME is a new volume name (e.g. WIN) and $DISK is a target disk identificator (e.g. disk5). Alternatively, you can try GTP partititon style instead of MBR (recommended for UEFI = newer Windows distributions)
  4. To mount Windows installer image, run: hdiutil mount ~/Desktop/$WIN_INSTALLER_IMAGE.iso where $WIN_INSTALLER_IMAGE is installer image name.
  5. Copy all files to the USB drive, beside the "install" file (if it's over 4GB size): rsync -vha --exclude=sources/install.$EXT /Volumes/$WIN_INSTALLER_NAME/ /Volumes/$WIN_USB_NAME where $EXT is wim or esd, $WIN_INSTALLER_NAME is the mounted Windows installer volume name and $WIN_USB_NAME is target disk name.
