I recently installed BackTrack 3.0 on my hdd and evrything worked youst perfect and the suddenly i turn on computer i login as root and then i try to start KDE.

with command startx
and i get message
-bash: startx:command not found
and then i try command sudo and again
-bash: sudo:command not found

Evrything worked just fine,and i`we booted BT3 couple of time before this happend, i realy dont have idea what happend. And then i tryed to boot from live cd, and just the sam happens. So i cant even install it once again.I`m really confused.
