I have plugged my HDD into my motherboard through SATA cables, but, it shows all my SATA ports as being empty in my BIOS. And

This is a dumb question, but do you have the power cable plugged in?
The other thing possible is AHCI is messed up.

Yes, it is plugged in, it's spinning up properly, but the SATA cables isn't being registered to the motherboard in pair with the HDD

It may seem really dumb, but some hard drives need drivers in order to operate. Most recent motherboards support driver installations for them from the bios. If your bios doesn't support the driver update process, try updating your bios. What motherboard do you have?

Asus 970

Ok, I assume you are talking about the Asus 970 Pro Gamer Aura motherboard. (good choice) Try and find the latest bios update for the motherboard, download it on another PC, and look up how to install bios update via USB stick. (sorry, i have never had to do a bios update before) If that doesn't work, try to install the HDD drivers using the disc that has the drivers from Asus. If that doesn't work, I don't know what to do. You might want to call Asus and see if their support department can help you. The only thing I can say if you get to this point is that you should give as much information about your hard drive as possible, and good luck.

Cheers!

Another thing, most OS installation disks come with HDD drivers on them, so attempt installing your preferred OS (Vista or up) and see if the drivers can get loaded that way

Cheers!
