Windows 10 is installed on my main SATA SSD, but when I remove my old 160GB HDD to replace it with a recently wiped and repartitioned 500GB HDD, no OS is found on any of my drives. I dont know how I can make it so that my SSD is recognized as a boot device, seeing that it looks like I can only boot windows when my old 160GB HDD is installed too. How do I fix this problem? I have a feeling that the Windows boot partition is stored on the old HDD, but I don't know much about windows to try and move that to my SSD or something else.
