Installed a new mobo and after installing it windows couldnt boot cuz i dont have the drivers installed -> fresh windows install required. So i put my old mobo in and every needed part gpu, cpu, ram and the other stuff. I booted my pc so i could make a backup, but it wont detect the hdd where all my stuff is at including the OS. Tried to switch cables and their places but nothing is working. Help! And yes the hdd has worked fine before.
