I always come to this forum when having computer problems so I figured I would look for some help on my current problem as well. My friend bought a laptop from best buy about 2 years ago, runs fine great laptop. Another friend of ours must have at one point for whatever reason re installed windows 7 on it with some random key. Now it runs horrible, I decided to look at it for him and reinstall the operating system again to make it run properly. I have no disc from Lenovo so I saved the .iso to a usb drive.
I used Jelly Bean Finder to located the product key but at the time I had no idea of the previous reinstall so it pulled the wrong key, not the original! Of course the Microsoft sticker on the bottom is half worn off so I can only see 15 of the 25 characters of the correct key that I need. I called both Microsoft and Lenovo and none of them have keep records of the keys on there computers which I can't believe. I even went to Best Buy where the computer was purchased and they also do not keep records of the keys on the computer. No one has a record of the key, just the sticker on the bottom! So now I am stuck at the part of the install where you enter the product key, which I don't have. I could understand if I stole the key or something but it was purchased legit. I have no idea how to fix this and look forward to some input.
