X and Fluxbox :: error when starting x

After I get the menu which I need to choose xserver, mouse ect... the computer writes some thing about error in 100 +-something line and that it can't finds /usr/sbin/xsetup.sh
then it writes "hdb: lost interrupt" until it fills the screen.
The CD works on another computer, so I don't think its the problem.

Are there any cloop errors? Sounds like the cd drive may have issues with that cd. I have had one computer work well with a burn but another spew numerous cloop errors. I've had this problem particularly with cd-rws.
