I don't think it would get that far if the problem is the Legacy settings. Have you tried a UEFI install? UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums.
Try another installer. In fact make sure you tick off everything in the list I gave in Post 42 without missing anything. Those steps solve 90% of install issues.
But it seems you do get installed before problems start, so I would test the hardware from Troubleshooting Steps for Windows 7. If you have another HD try that also.
