I have the Windows 7 Home Premium Upgrade DVD and just successfully completed a "clean all" as described in your DiskPart instructions (I previously had Windows Vista Home Premium 32bit O/S installed...now nothing, of course). Since I only have an 80GB HDD that will never need the dual-boot feature, how do you suggest I best partition my drive (e.g., recommended space allocation for Windows 7, recommended space allocation for System Reserved (or none whatsoever?), create a separate partition for Program Files or just use the C: volume/partition)?

Thank you!

NOTE: Of course this is an extremely small HDD I'm working with, but this is not my primary computer and simply want it running as clean as possible with the best performance possible.

I followed your instructions exactly, but now at the Windows product key screen, it is saying that "The product key is not valid". I just purchased this genuine copy of "Windows 7 Home Premium Upgrade" yesterday at Wal-Mart. Ideas?
