It has been a long time since I've used Fedora Linux distribution, so recently I installed it. Fedora 15 has changed the way you change the run level on it.
To change the run level you need to issue the following two Linux commands as root:
rm /etc/systemd/system/default.target
ln -s /lib/systemd/system/<target name>.target /etc/systemd/system/default.target
