I have a toshiba tecra a50, replaced my hdd with an ssd, it worked just fine. When I used a caddy to reinstall my old hdd with removed system files, the pc won't boot from my ssd to start windows automatically. I have to press F12 everytime I start my pc to select the boot device. I've already set my ssd 1st in boot priority and disabled booting from other devices but it doesn't seem to work. Is there anything else that I need to do?
