Hello, everbody,

I forgot the logon password of my laptop with the operating systm of windows 8. And I want to resinstall a system in F:/ . Usually, I fromat C:/, but now I want format F:/. I did not try this before. If I do format F:/ and install win 8 in it, will there be two systems, or will there be any other problem? Could I format C:/ and will the former password be in valid after reinstalltion?

Thank you very much!
