I am planning to install Windows 8 on my machine and I'm wondering what the best way to go about this is based on my rather unusual situation:
My machine originally shipped with (what I understand to be) an OEM copy of Windows Vista Home Premium (32-bit). This was installed on the machine when I bought it - the hard drive contained two partitions: the Vista partition and the recovery partition.
Now, here's where things get a little bit confusing - I eventually swapped out the original hard drive for an SSD and did not preserve the Vista installation (or the recovery partition) on the new drive. I have been dual-booting Ubuntu 12.04 and Windows 8 CP.
Now I would like to install Windows 8 on this machine and I should definitely qualify for the $40 upgrade offer - my only problem is how to go about this, since obviously the installer needs to verify I do have a valid licensed copy of Windows Vista.
There is a little sticker on the bottom of the machine with the Windows logo and a serial number - will that work? I still have the original hard drive with Vista and the recovery partition if necessary. I was wondering if I could clone the recovery partition, dump it on the SSD, perform the recovery to install Vista on the machine, and then upgrade that - but I'd love to hear if there is an easier way.
Edit: some comments below made me realize that I missed a couple of things in my original question (sorry about that).
I have a 32-bit copy of Windows Vista and I would like to end up with a 64-bit copy of Windows 8 (I am using the 64-bit copy of the Consumer Preview right now).
Obviously a direct upgrade from 32-bit Vista to 64-bit Windows 8 isn't going to work. I was hoping to perform a clean installation of Windows 8 regardless of whether I start with my Vista installation or not.
