I will say it before someone else does, do not put urgent in your title name. FIRST

And how is that urgent even to you? Forget about anyone else.
If you can write I hope you can write english. And if you can why not use it to search google a bit.

Why am I even reading this..

Lol I have a feeling there might not be any good answers for this until the flaming ends...

You can use su
Take a look at
http://www.fedorafaq.org/basics/

Switch to a terminal console by pressing Ctrl+Alt+Fn (assuming that you run X Windows GUI by default, where Fn is one of the function keys, but not the one where XWindows runs). Then simply type 'root' as the username and type the password, if you know it.

Reply:
If it boots you can certainly log on, as a user or root.
Pressing Ctl+Alt-F2 (F3, F4, F5) will open you a tty terminal with a login prompt, there you log in, using your name and password. If "root" account is not enabled you may login as a User then enter command: su <Enter> give password for root.

You can do google for tutorial, or download this tutorial in my signature below, read first the basic ideas for Linux system (not all at once) then you will feel confident to solve your problem. For any problem that may come later you can browse over the tutorial, open xpdf, press Ctl-F then enter word you wanted to search, using this tutorial is easy if you know how to search on it.

Hope this helps.

Good luck.
