I recently purchased a laptop. The OS installed in my laptop is Fedora linux. But yesterday on of my class mate entered into the SSH tunnel on my linux laptop. He changed the default runlevel to 0. I don’t know what does that do. It lets it boot then goes to runlevel 0 and finally shuts down. Now I am unable to change the init level. I tried a lot but I failed to change it. Is anyone aware about such issues? If yes then please do the needful.
