do read some guides reg linux user admin and file system hierarchy
dont login as root in Linux for daily use.root is administrator.but note down ur root and passwd somewhere.now login as root and open a terminal by right clicking on th desktop or from the menu Applications>Accessories>Terminal.now do u remember what do u set as local username?if u forgot the passwd for local user,u can reset from root terminal as follows:
^where username is ur local username.now write down this local username and passwd somewhere for u to remember.
Next,Do you get a GUI(graphical user interface) when login with username and passwd?I cant make it from ur answer above.u may be getting a fail-safe terminal session.this means no Desktop Environments are installed.for that
u must have to select in Installer to install Gnome or Kde or Xfce Desktop Environments while installing.from terminal,u can mount fedora dvd and try installing Gnome rpms etc and i'd say, it is impractical.
But since if u see a GUI gdm from where u login`ed and got a fail-safe terminal session.u can the terminal after "#" prompt type:
*iup.in/img/praka123/thumb/ndgui.jpg
^if it works to show u a gui menu with available options,insert ur FC DVD-then make sure u ticked/selected GNOME or kde or xfce-any one of them and other needed packages from the list.if u want programming(c/cpp/java/.net)
select programming option.now press the install button.
Also when u get a gui login prompt(it is called gnome desktop manager or gdm)
make sure in options,u selected Gnome or kde or xfce for login.
Since i am a debian/ubuntu user my explanation may not be 100% correct.but hope it Solves.
Now-do you not at all getting display(gui) only a tty with login prompt.reply here with ur pc specs esp graphics card or onboard card name.
Best of Luck and have a look at this Linux basic system administration guide afterwards:

I advice you may feel it easy as Linux File system hierarchy is completely different(UNIX-like is Linux too!) and you can sort some guide on file systems like below one:

and a detailed one below:
