My hp pavillion dv6 got a virus that destroyed most everything and now my boot mgr is missing. the com came with win 7 pre installed so i dont have the windows 7 disc. I tried and made a windows 7 repair disc off of my friends computer, and when i used the cd on mine, it said i have no previous image to revert to. So as of now i got a much larger (seperate) cd to burn an image from the same computer. How can i use these cds to fix my computer?
