If your running Kde be sure the two windows you open are the "file manager super user" windows (I think its system>file manager super user mode menu)..Or you could boot Knoppix and say "knoppix 2" at the boot prompt and then at the root prompt it boots you to mount your drives with "mount /dev/hda1" or whatever then use the cp command or say "startx /usr/X11R6/bin/icewm" and you will be root and have full premission with whatever windows you want to open and use.
