I just bought an HP ultrabook with Windows 8.1. I'd like to merge and format the partitions on it and install a clean copy of Windows 8.1. Unfortunately, and for the first time, I've noticed that the laptop doesn't come with the usual sticker on the bottom or certificate in the users manual. How can I do this? Please correct me if I'm wrong here:

1) Download a program like Magic Jelly Bean that may be able to show me an activation key, as opposed to the full product key listed in the System app.
2) Download the Windows 8.1 bootable USB installation software from Microsoft. I read that it will prompt me for the activation key before setting up on a USB?
3) Run the installation software and use the advanced options to format and change partitions.
4) Install Windows and everything should be activated?

Did I miss something or has someone else in a similar situation done this?
