A1534 does not see hard drive

I found one state man from Apple user that states he had the same issue as mine: laptop doesn't recognize the SSD.

Good that he posted that. Anyway here is my question: Why my A1534 2015 year does not recognize my ssd?

I boot to Apple disk image media and all I see in Disk Utility is image Media,nothing else.No hard drive! I need help!
