Can your computer run without an operating system?

Author's Note

Starting from scratch on a computer is not for amateurs. If you're a serious engineer/developer, it is conceivable to use a computer without a preinstalled operating system. But for those of us who use their computer to do such vital tasks as keeping a spreadsheet of their Christmas list or checking out the latest Ryan Gosling meme, it's probably not so necessary. And remember, an operating system-less computer is only good for one program. Probably worth it to pony up the money for an operating system.
