Now copy content of folder on usb stick (format first and volume write WINPE)
Now remember,when you start tablet you will be blinded and steps you will do will be next.
Open tablet and start tap F7 and tap it for some time to be sure you will end up in bios settings.
now you have tap DOWN ARROW on keyboard TWO TIMES and press enter.
Now wait ( took me more then 5min in feeling nothing happening)until you will see chuwi logo appear on screen and after that turn tablet off and on again,let it do his things,logo will appear and disappear couple of times but then you will log in back to windos.
I hope it will be helpfull for some of you and sorry for bad English.
Good luck!
