Thread: Dual boot not performing

I dual booted windows 7 and windows 8 and I commenced it up and played with windows 8. Then I required to go back to windows 7 so I shut it down and clicked on windows 7 operating system then the screen departed black it commenced updateing and now it wont let me going back to windows 7. It also says SFcon.dll is not operating.

I am quite sure that while doing the setup, you have messed up with the boot settings and that this is the cause that Windows 7 get unbootable. You can make utilize of few VMware to get this defeated.
