Mobo fine. Hard drive fine. Just not playing together.

Building a new PC for a friend and HDD is not booting on my his motherboard. It recognizes the hard drive but won't launch windows.

His HDD WILL boot on MY motherboard just fine (so it's not a bad hard drive or faulty windows install). MY hard drive will boot on HIS motherboard with no problems (so not a motherboard or other component problem.

BIOS is up to date. Same Windows 7 x64. Gets to a black screen with flashing cursor after BIOS menu and doesn't respond. More than sufficient power from PSU.

I have never heard of this and can't find anything on it. Very strange.

MOBO: Gigabyte H110M-A
HDD: 1 TB WD HDD 7200RPM

Other notes:

*Have tried UEFI and Legacy. Boot priority set for Hard Drive.
*Using the same SATA ports and cables.

What else can I try? Does anybody know what else I can do? I've tried testing out different settings in the BIOS to no avail.

Welcome to Tom's Hardware, @Tetra19!

Good job with the troubleshooting you have done so far! Have you tried re-creating the bootable Windows 7 x64 installation media?
Since BIOS is up-to-date, I'd recommend checking if you got the latest SATA controller & Chipset drivers installed for that specific mobo model. You can do that from the manufacturer's official website as they got the latest updates there. You should also check how the system will recognize the WD HDD after a BIOS reset, too. If that doesn't help, swap between the SATA modes in the BIOS settings and check if that will help you recognize the hard drive properly.

Keep me posted! Hope this works!

If you are trying to migrate a pre-installed Windows onto the new PC it probably wont work and you'd be better off reformatting the drive and doing a clean install from USB/ODD
