If you decide to go the dual boot route, I just did that. It did not overwrite the Windows 8 Recovery image, so it should not be a problem installing the way you are thinking about and removing later. The dual boot was set up fine and no problems so far (5 minutes
)
I do not know if this has been discussed in this forum, but if you want to be set up with a local account, you need to disconnect the system from the internet prior to installing. If you do not, it will force you to log in with a Microsoft Account ID. And it tries again when you go to the Store, make sure and look for the small type at the bottom of the page.
