Trying to revert from failed new MB install, now Win 7 won't boot.
I made the naive mistake of trying to upgrade from a Biostar TH67+ MB to a MSI Z77A-GD65 MB using my existing Windows install.
After I installed the new MB and the new drivers within Win 7 Pro 64 bit, the machine woudn't boot. So I reverted to the Biostar MB and it still won't boot. I have tried Safe Mode (which just hangs) and I have run Startup Repair several times.
Suggestions on how I can further troubleshoot/repair the boot?
