Really thanks. I have the same MB. So i can try! 

Thanks a lot. This is the third week for me with this problem. Please don’t forgive to tell witch MB you got   

What MB have you? google drive it’s fine. May help someone as me. i think it’s bios file, with renamer.exe? for sure it’s dangerous for the bios… really hope resolving thanks
