You seem to put a lot of time and effort into posting for "someone". Why doesnt "Someone" who wants to know so badly how to do something behind "someones" back, log in, create himself a account and ask his own questions? As Roswell said, your story sucks. If you dont know, admit that and ask straight out. It gets a lot faster, more direct answer. Ive said before that someones social engineering skills were as sharp as a snowball. In your case Id have to say a marshmellow might be closer... Please dont waste our time. If its really your friend calling you at 1 am and he dont know about disk partitions and wants to play with a different OS he really needs to log in, be quiet and READ his a$$ off.
Just my proverbial 2 cents.
