If the OP's problems involved UEFI, a configuration error would have been generated when trying to set up a drive. He also tried both versions.
Since it was not, I must assume the problem is a hardware one. UEFI is only the bios, not the OS. If it loads all the files, but is not able to start Windows, perhaps running the Windows 7 compatibility checker might help.
Again gregrocker, a system defaults to a particular boot version. All of mine default to a MBR install. The Install will take care of whether the drive is configured as GPT or MBR. But, of course, there are situations that might alter the normal install.
