I am in the process of upgrading to XP Professional and
got the following error: "The signature for Windows XP
Professional Upgrade is invalid. The error code is
800b0100. No signature was present in the subject."

Now, I am stuck in this continuous loop where the computer
restarts and goes right back into the installation mode
(step 4 - Installing Windows) and then I get the error
again. Can someone please help me to either fix this or
at least help get out of this loop and back to XP home?
Thanks.
