What is the best c compiler for developing OS's? Also, are there any good tutorials about development of operating systems?

I'd imagine everyone has their own preference. I'd suggest GCC. Not only is it used by more tutorials (and therefore easier for a beginner to pick up quickly) but it (along with the GNU binutils) have several excellent tools for osdev.

personally, i prefer the Visual Studio (and its optimizer is considered second only to intels -- which is very expensive), but as jeff said, everyone has there own opinions

lots of good tutorials on bonifide
