Upgrade from XP

That is incorrect, you cannot use the upgrade disk to install on a new empty drive. There has to be an existing OS first. See this official site

It is correct read the rest of the question in your link.

Well I apologize for my response, but even all thru that link, there was still no clear cut certainty that the process can be done on new hd.

Well for clear cut certainty we would need an upgrade disc to test , which nobody has yet. Given the similarities in the install method between vista and seven and the fact that microsoft said the same thing about vista and was proven wrong, the general consensus is windows 7 will work in the same manor as vista did.
