Ultimate Boot CD

First time user here, just downloaded UBCD and burned it to a CDR. It runs and boots to the Main Menu just fine, but the Hard Disk and FIle System tools don't run (I choose the option, it flashes a black screen, and goes back to Main Menu.) The other options however, all work fine.

Running on an Intel 3ghz, 768mb RAM

Any help is appreciated, thanks,
Graham
