BIOS not recognizing HDD

I connected the hard drive to the SATA1 slot on my Asus mobo and to the
PSU. I turned on the computer, went to BIOS set the HDD to first boot
priority, and reset the computer.



If I go straight to BIOS again, it doesn't read it on the main screen. If I let it run, I get a disk boot error.





Any ideas?
