Thanks for replying and the guide but thats not my real problem lol I cant even get to OS cause i have 2 hard drive now, one Sata-I that iam already using that works fine and one i just bought which is this Seagate. When i plug the new one by itself or both in my Mobo, it says "Hardware initiated fail. check your device. Bios does not be installed" lol And when i try to just directly plug my hard drive in Windows, it just freezes and just do anything. So i thought there is something else that i have to do to get it up and running.
