Most of the other questions have already been answered, so I'll do it as code quotes
then hit enter, it should then ask for the root password which you type in and then hit enter again if the prompt changes from $ to # you're there.
Passwords etc are case sensitive.
All this is in other replies.
The only other thing I can think of, is whether you're using gentoo linux? because if you are, and you didn't make sure that your user account is a member of the "wheel" group. If that is the case, you'd have to log out, then back in as root and that'd have to be CLI as you probably can't log in graphically as root (usually disabled by default).
Dunno if any of thats any help or not.
