How to boot to cd?

Tech-Archive recommends: Fix windows errors by optimizing your registry

This is my boot.ini. Can someone explain how I can tell if it is set
to boot from CD.

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows XP Media Center Edition" /noexecute=optin /fastdetect
