I'm having hardware problem when it comes to installing a another HDD, i wanted it to make it my master HDD instead and the main HDD i'm using becoming a slave drive, everytime i boot up i'm getting a black screen and saying it could not find my HDD. I was told that it couldn't be my HDD because apparently it's configured properly (my friend did it for me) and I was told to do POST to check my hardware errors or any errors thats preventing me from booting my computer properly. Anyway I want to know how do you POST? i want to know whats wrong with my computer, i have many documents/files stored there i'm afraid i'm going to lose it. thanks.
