Vista - Installing Vista Home Premium

I had XP Media Centre on my AMD 4400+ & decided to upgrade to Vista
All good - purchased Vista Home Premium and installed it (on a temporary
drive). This allowed me dual boot between Vista32 and XP Media while I
decided that this will work for me
I then ordered a Vista 64 dvd.
I formatted my "C" drive to ensure a clean install
I processed the clean install without entering licensing information
The clean install failed right at the end with "The installation was not
successful"
I re-installed, this time successful
I then ran the software again and used the "upgrade" option
But this fails every time with exactly the same message at the same place

The last few steps are:
Copy windows files - successful
Expand files - successful
Install features - successful
Install Updates - successful
Complete installation
Reboot
The installation was not successful
Reboot & rollback to unlicensed version

How do I continue from here?

I have had success after problems like yours by deleting all partitions (
not just formatting ) first on the hard drive I am going to install it on.
