I am a second year 4th semester computer science student and I want to make an OS for my fourth year major project. I intend to write the kernel in c or c++ as these are the languages I am most comfortable with. I do not know assembly.
I want the OS to be like the DOS i.e. without a GUI and the OS should perform the most basic of operations like make a file , delete a file and display a file, that is it.

Please could somebody guide me about where should i start from, what all should I study and the recommended books.

You talk about a file system, not an OS. The file system is just a part of an OS (please note that an OS does not necessarily need to have a file system - see many embedded system OS).

Implementing a file system is kind of useless (you have no benefit in re-inventing your own or re-implementing e.g FAT16, etc.).

Try to find a more rewarding project topic.

  • If you want to do low-level stuff, you may design and implement a boot loader (maybe with some useful specific feature)?
  • Think of what C/C++ is useful for (compared to Java/C# or web based server/client stuff): low-level processing, things that must run fast (not going over a virtual machine), ...
  • You might invent something that can be ported: e.g. your own shell with some embedded control flow language that can be ported to Windows/Unix/Linux/iOS/Android/Win Mobile/... - add a mechanism to add specific commands so that you can extend the shell with OS specific commands.
  • ...

You find my coordinates by going over my profile. But I prefer you posting questions on CP. Answering CP questions is kind of a hobby of mine and I can not spend any business time on that - so I choose the post to answer on a per case base. You best find a mentor at your location where you can discuss things 1:1 looking into each other's face.

Well, some interesting articles; but hardly enough. It needs learning of a lot of fundamentals, and, importantly, CPU architecture and programming. It seems to me, it does not look like OP is serious enough... Anyway, a 5.

Thank you. Yes indeed, building an OS is a complex task.

thank you Abhinav and i am serious about making the OS. since here almost every other guy submits an e-trading website as his major project so really wanna stand out.
