If you got a prompt, it means Fedora is running. Try entering "startx" (w/o the quotes). If that doesn't work, then create a new user by entering:
useradd -p password username (Substitute your choices for "password" and "username"
Then, re-boot and login with the new name.
If startx does work, you'll be in the GUI as root, which is not good. Create a new user, then ctrl-alt-backspace to re-start the X server. Then log in with the new username.
