So I got another hard drive installed on my computer by a third party. They installed windows (which was one of the problems with my old drive) so that my computer would run properly. I took the computer home and when i booted it up it asked if I still wanted the secondary drive to run. It also gave a warning that if I selected it to run then it might interfere with windows on my new drive. So i selected No and know I can’t access anything on my old hard drive. I’ve looked in Bios but can’t find any way to turn my old drive on as a secondary drive (non-boot up). I’ve also looked in the hardware manager and don’t see any disabled drives. Ideas?
