I recently purchased a Samsung 850 evo 250gb ssd with the intention of making it my boot drive with some games on it. I used Samsung data migration tool to transfer the data across from my old HDD. The transfer was successful and after rebooting a few times and launching windows from the SSD I deleted the data from the old hard drive. Next I tried to run Black Ops 2. When ever I joined a lobby that had already started I would be fine. But when I was in the loading screen for a lobby that hadn't started yet the game would crash and restart. I looked at some posts on the Steam community forums and found that updating the BIOS settings of you motherboard could fix the problem. So I found the new software from Gigabyte's website and updated the settings. I made sure that I was updating the version for the correct motherboard. When I restarted I found I could not boot to my SSD. I could access my BIOS fine but when I selected the reset PC from the windows repair options it said the drive was locked. I tried to unlock the drive by changing partitions but was unable to. I finally decided to install windows on another hard drive from an old computer and was able to load windows on that. I can access the SSD fine from windows now but I still cant boot to it. Does anyone have any ideas about what could have happened. My motherboard is a Gigabyte 970A D3P.
