Computer wont read my hard drive

[briantheman890]

So i build a newcomputer yesterday.
I decided to use my old SATA hard drive from my computer, it has my OS, and other files on it.
I get everything put in, but when i start the computer it says "no hard disk is detected".

I enter the bios menu, and i notice it recognizes that it is in there, as well as my disk drive.

How come it wont let me load my hard drive, and it doesnt detect it when i start it up.. but BIOS sees that its there?
How do i fix it?

Check the HD Drive cables.

Put the hard drive in the first boot order and try again.

Also being a new build it's possible something isn't connected, it happens.
It's doubtful a HDD with an OS will boot and run in a computer other than the one it was installed in initially. The OS takes a hardware "picture" when it's installed and the MS Genuine Advantage Technology will invalidate it.
