I've a Surface Pro 2 and want to delete all partitions and reinstall Windows. I created a USB recovery drive thing, restarted Windows using Volume Down + release when Surface logo appears, and find the menus completely unhelpful. I'm asked for a recovery key, which I don't have and don't want - I want a 100% clean, fresh-like-a-baby's-bottom install of Windows. The other thing I tried was to boot using my Windows 8 Pro install CD(DVD?) I bought for my desktop PC, but it prompt me for my product key. I can't use the key from the install CD because I'm using that on my desktop. The Surface Pro 2 packaging and documentation doesn't include a Windows key. I've read online that the Windows product key is in the BIOS, and automagically appears. It doesn't. Any ideas how I might get this done? I appreciate any help/pointers.
