Hi, recently I've installed window 8 consumer preview on my laptop (m11x r1), after noticing that it will expires on 1/16/13 I've decided to reinstalled window 7. During the process i just put the window 7 dvd into another computer and put it on my thumb drive, then, i plug it into my laptop and installed it just fine. After everything is completed i notice that there are several things gone. Is there anyway i can put window old files back to my new one? Also, i notice some of my drivers (wireless, graphics card gt 335m) are gone, i couldn't even see those devices on my device manage ( not listed). Someone please help!!!
