Note: For 64-bit Windows Vista, download etfsboot.com and put it into “\Vista\boot” folder. Or users using WAIK (WinPE), the etfsboot.com can be found at %Programfiles%\Windows AIK\Tools\PETools\amd64\boot\ folder. So simply replace -bC:\Vista\boot\etfsboot.com with -bC:\Program Files\Windows AIK\Tools\PETools\amd64\boot\etfsboot.com when making 64-bit Vista DVD image.
