For my new PC I have a 240GB SSD for games and it has my OS so all of that runs faster. Then I have a 2TB HDD that doesn't show up. I went to Computer Management and went to Disk Management. I see the 2TB and I can right-click and "Mark Partition as Active". It says are you sure you want to do this because if this doesn't have an OS then your computer might not work. It doesn't have an OS but my SSD does, so should I do that or this there another way? Thanks! I have Windows 10.
