Boot up your Vista CD. Remove the C: partition. Restart. It will
prompt you to install the full OS CD, if you have an upgrade CD for your
previous OS. You just insert your full OS CD and when prompted switch
back. It is called security for Microsoft. You can only upgrade a full
OS version. You can have issues with OEM full CDs. On some versions of
Windows you can't upgrade OEM. OEM must stay with the original box.
You can only upgrade full retail versions. I usually just buy full
retail versions of each OS so I can install the previous OS on another
box.
