Operating System Help

[Rocker98585]

I was wondering if I could make an operating system with Visual Studio 2013 with C++. I was thinking about making one that is like MS-DOS. I want it to be text-based. I was thinking if somewhere out on the web there are pre-made kernels from assembly. If there aren't, I really don't mind. Programming is awesome. About how long would it take to make a text-based OS? I might call it Modern Style Disk Operating System, or for short, MS-DOS

You won't be able to make it only with VS. Also you will need assembly knowledge and information on the internal PC workings.

I know that, I don't mind learning another programming language. I have plenty of time to learn everything else. I was just saying that I have already started working on the C++ of the operating system. I'll write the assembly later.

Is Assembly a language? xD I think that machine code is too hard.
Mind in something useful, like a browser or something. You can also create a virus (real virus, not shutdown -s -t 00 -c "ur facked cus i shut down ur pc").
