I think you're trying to run both Windows 7 and Windows 8 at the same time but installed Windows 8 before Windows 7. That’s likely the issue. The bootloader for Windows 7 will replace the one for Windows 8, so your older version won’t recognize the newer OS. You should install Windows 7 first, then Windows 8.
