When the machine very first powers up, you should see at least one message on the screen that has words like "F12 bios" or "F9 boot sequence". It may be F5 or another function key. These messages last only a few seconds. You want to get into your bios to
change the boot sequence.
Try each key you see in the messages.
Lean on the key for a second or two. This will cause the boot sequence to stop and go into bios setup. Or boot sequence setup.
If you don't like what you see, cycle the power.
Somewhere in one of the screens you'll will find something about what devices you want to use to boot from and the order to look for the devices. You want to boot from CD.
