Hi guys,

This morning, after booting the computer, I failed to enter the Windows 8 operating system. So I tried to repair it by overwrite installation with the guidance of the original system disc. But it required me to enter the administrative password, while there were no passwords set before. Then I pushed Enter, it displayed me C:/ windows/. And then there was no further response.

Can you show me what shall I do?

Thanks very much!
