After hitting "ESC" in the boot screen to get to the Boot Menu, I would select the DVD-RAM drive, then press ENTER. So far, so good. The problem was that then there followed a one-line screen asking me to click Y if I did want to boot from the DVD drive -- and it flashed past so quickly that by the time I read what it said, let alone got to hit Y, the computer had already moved on to loading Windows. I guess that's one drawback of a faster CPU.
(Side question: If I have already entered the Boot Menu and indicated that I want to boot from the DVD drive, then why in heaven's name does it even ask me whether I want to boot from the DVD??? I already told it that that's what I want.)
I finally defeated the PC's scheme to prevent me from booting the CD, by starting to click Y repeatedly as soon as the Boot Menu disappeared. Only then was I able to get the familiar Spybot Windows PE screen.
