I have a volumn license with Microsoft, and would like to upgrade my new Windows 7 Ultimate machine, to Windows 8 Enterprise, which should work well my company's AD network. I don't believe there's an upgrade path, which will retain all of my settings, etc, so I'll have to do a wipe-and-load. I'm assuming that at some point, during the process, I can tell it to delete the partition and re-create it. Is there anything else I need to do to flatten my machine to install Windows 8 Enterprise, or is that it?

Just wipe hdd and install Windows 8. – Ramhound Nov 8 '12 at 17:37

According to this Wikipedia article, you cannot upgrade from Windows 7 Ultimate to Windows 8 Enterprise. As far as I know, this only means that the installer is not able to do a "soft" upgrade which keeps all your files, settings, etc., but will instead do a "hard" upgrade which wipes Windows 7 Ultimate and then installs itself, or you can install it alongside it, keeping Windows 7 intact. This, of course, is not possible if you're dealing with some sort of upgrade-only solution, which requires an existing compatible OS.

I would suggest you do the following:

  • Back up all your important files.
  • Run the Windows 8 Enterprise installation.
  • There should be a point where you have the option to manage your hard drive partitions.
  • At that point, you should be able to wipe the Windows 7 Ultimate partition, and use the freed up space to install Windows 8 Enterprise instead.
  • Complete the installation.
  • Move your files back onto your PC.
  • Enjoy! :-)

Transferring user settings should work by using the Windows 7 Migration wizard - to copy files and settings to an external drive - and then use windows 8 "Easy Transfer" to read them back. Here's one person's blog on doing it this way.

Use Windows Easy Transfer to backup your files and settings from Windows 7, then wipe, re-install, and restore your files and settings.
