Ok, every time I boot, a message pops up saying that I have an unstable driver on my PC, and the location is unknown. I managed to find that driver...or at least 4 of it's vital files and deleted them. Later, when I put a disk into my dvd drive, it did not play, and later I discovered that the system did not see the drive (obviously, because the files I deleted were from the driver for the drive). Fourchenatly, I was smart enough to burn those particular files onto a disk before I deleted them, but now that my drive isn't recognised, I can't get them back on. So my question is: If I get those files onto a flash drive (from my disk on another PC) and drag them across into my drive (where I found them) will it make my system recognise the drive again?
