Please verify that you're using MBR and not GPT by examining your partition table. In fact, please run Boot Info Script
and post the RESULTS.txt file that is produces, either as a link or between code tags.
Mobo BIOS is set with secure boot turned off, and I assume EFI as well.
When debugging problems like this, don't assume!
All hell broke loose when I tried installing Mint15. When setting the EFI bootloader "drive" as the first thing in BIOS, it would normally boot Mint without a hitch. When I'd go to load Windows, I'd get an error of invaild EFI path.
This symptom strongly indicates that you've installed an EFI-mode version of GRUB. It could be that Windows is (or was) booting in BIOS mode, and that your previous Mint installation was as well; or it could be that you were running in EFI mode all along. The proper repair depends on which of these is the case, and the Boot Info Script output will reveal the details necessary to make a diagnosis.
What needs to be done either to fix this, or the proper steps in getting both installed as a fresh install? Can Win7 even use the EFI and GPT?
The proper repair depends on whether you should be using BIOS/MBR or EFI/GPT. Windows 7 can boot in EFI mode from a GPT disk, but if it's currently configured for BIOS/MBR booting, it's likely to be easier to get Linux booting that way than to adjust Windows.
