The hard drive that I want to move has all my files on it. I want to move it to a newer computer as a secondary drive. The problem is that the newer computer is running windows 10 on a SSD to boot and the hard drive that I want to move in already has windows 7 on it. I don't think this will be a problem but I wanted some advice to just make sure. If anyone has any ideas / needs more information, let me know. Thanks!
