A., Have you tried F2 and the Boot menu to see if the CDROM is listed
ahead of the hard disk? You might also give Removable Drive priority
so that a usb stick could also be used for your boot up device.
Anyway, make a few tries, I have found it may take four start ups on
average to get the live/install process to work. Also check the
install disk for scratches, as they do wear out eventually. Good luck.
