I have not tried the selective setup in a very long time. The last time 
I used it was when sendmail would take forever during Redhat 5.2 - If 
you chose not to run one of the services, chances are the service needed 
to be running before the following services could run successfully.
If you allowed the system to boot up as normal, without selecting the 
services, the OK in green or the FAILED in red should be shown on the 
screen.
If you let everything start, something might be missing in your install.

This is the terminal, much like the DOS prompt of days long past. From 
this terminal, you start and stop programs. You are in an interactive 
mode without a graphic interface.
At the login: screen is where you enter your login. Since you are trying 
to fix the installation, the root account would be what you want. Enter 
the word root. Next you should see a password: prompt, enter your 
password for root.

Now you can try to get your X working. First you will run a program 
called system-config-display. You will want to type the below to get a 
clean configuration.
system-config-display --reconfig
Now, X should try to start and show you a GUI where you can pick your 
display if not detected and adjust your screen resolutions to the 
desired values.

If you are able to get a successful X configuration and the program 
exits, you might create a normal user with adduser username followed 
passwd username to get a normal user account. Then you can hit Alt-F2 to 
get you to another terminal. For this terminal, put in your newly 
created username for the regular user. Then the password that you set 
for that user.
After you are logged into the second terminal (ALT-F2) as a normal user, 
type the command startx to test if you can get to a GUI mode. Your GNOME 
or KDE desktop should come up. If this works, you can edit out the rhgb 
entry permantly with an editor. You must be root to make the changes. 
You can use any editor that you want to do remove the entry from the file.
If you are still learning and don't know a lot about all the editors and 
stuff, you can press the a key to remove the rhgb entry on each bootup 
until you know the system better.

I'll save the links for documentation to those familiar with the 
available documentations. I understand the problem with quiet and rhgb 
because of the lists when the graphical bootloader was introduced. Our 
documentation specialists for the community can give the best resources 
to check.

The command telinit followed by the runlevel number should stop services 
in the runlevel that you are in and start services in the runlevel that 
you are changing to. Of course, runlevel 6 is shutdown and should just 
turn off your computer.
I have changed successfully from runlevel 5 to 3 and from 3 to 5. I also 
had luck changing to runlevel 1 from either 5 or 3.
Your reading up on the runlevels will probably give you a deeper 
understanding of when one runlevel is desired over another.
I know when X misbehaves (GUI) runlevel 5 is quite a mess. X will try to 
start over and over again.
Runlevel 3 is handy when you want a lot of shells for ALT-F1 through 
ALT-F6. You can run many different users and each doing a different 
task. You can also start the GUI from any of the users in the terminals 
that you have open.

Good luck and You might search google for documentation related to 
Linux. Documentation for Fedora Linux would cover Fedora/Redhat programs 
like rhgb and options to the kernel.
