Think you its working but with alert : system is booting in manifacturing Program Mode...

Once in Windows, download BCU utility and run the executable file to generate a configuration file. Modify the file to make manufacturing mode to go away by changing asterisk from "*Unlocked" to "*Locked" and watch for any errors.
