By inserting a USB stick, and then in the Boot tab of UltraISO, we choose to write to the hard drive to make the USB stick WINDOWS7 installation disk that we want.

But in the actual operation process, we will encounter a more troublesome problem is to appear: missing the required CD/DVD drive device driver, then our installation is no way to continue the following diagram:
