I recently bought a new hard drive for an older PC. It's outdated, but all of its other components worked, and my dad just needed it for some light internet browsing. After buying the new hard drive, I used my own PC to put a copy of Windows 10 on it. I then took out the old hard drive from the old PC, and put the new one in. After booting, it kept coming up with an error code saying "restart and select proper boot device". I've tried other options from the internet but none have worked. What do I do?
