I purchased a dell inspiron n5010 laptop 3 years ago. It came with genuine windows 7 home premium installed. But some days before there occurred some problem and when I booted the laptop it showed bootmgr missing. I had a lot of data stored in it so just to have a backup of my data I had install another version of windows 7 temporarily over the previous one in the same partition but I didn't remove the files of the old genuine windows and not even the recovery partition it is still there. So please can you please tell me how do I recover my laptop to the factory settings. I want it to be at the same state at which it was when it first came to me. Please help. I have the windows 7 installation dvd which i got with the laptop and also I made a recovery dvd using Dell Data safe when I got the laptop.
