I just bought a second hand laptop (Lenovo Ideapad 300) and it have a Windows10 operating system.. because i prefer if it is on Windows7 so i decide to reformat it, i can't downgrade it to windows 8/8.1 Because of the due.

after i reformat it, there's a lot of missing drivers, specially Ethernet and USB Bus controller, i already download to my other pc so i'll just copy it to usb and transfer it to my fresh reformat laptop, i can't install because my laptop don't have USB Bus controller.. please help
