Any help with this problem would be greatly appreciated as I am sure it is a small mistake on my behalf that I haven't noticed !

As my laptop reads from the disk everything appears to be fine as it runs through the Darwin screen, then just as the logo appears my laptop restarts and enters the whole process again. I've used numerous blank DVD's, all written at the lowest possible speed and still no change.
