So recently my old laptop's motherboard had a short and I had to get a new laptop. Now the new laptop has a terrible hard drive and I want to swap the hard drive from my old laptop to my new laptop. What files do I need to move from my new hard drive to my old one so it can boot up the new laptop? I do not want to format my old hard drive and lose all the data so if possible I'd like to just move the needed files from new hard drive to the old hard drive.
