Question

I want it run on a PC ...
Explain me please everything to understand and see if is posible.

Answer 1

I would start with either C++ or Java C++ would be my personal preference. You can work in any IDE and compile the code. The compiled code file should then be placed on the testing machine. I would start with something simple like recreating the DOS APIs and build upon that.

Answer 2

This is probably far more involved than you realize. Creating an operating system these days is a very involved process. The best language choice would be C and assembly. The compiled code need not have an extension. Extensions are something that an operating system defines, as are file names even. An operating system does not even need to have a file system! I would recommend that you research other open source operating system projects to get a grip on what it involves. Linux is an obvious choice, but smaller OS' would also reveal just as much.

Answer 3

Why would you want to make your own operating system? There are plenty of good ones available and some of them are even free such as Unix and Linux. There are more important things you should be learning about computer programming!
