So i should not worry about the gui right now, i just want to make it better that way i know what i want my operating system to look like, and right now it just a shell gui for DOS so it loads through DOS i have a kernel made and a boot loader that i have programmed, i just want to get it looking better thats all thanks for your post guys, i am open for any suggestions.

I'm not sure that I'd call this an "operating system" or even a "kernel" of any sort. Whatever it is that you "really" want to do with it, it isn't ready for it by any classical definition of an operating system. First, it sits atop of "DOS" and doesn't provide any operating system features with the possible ambiguous exception of "running" a "user program" like "notepad."

The code is horribly intertwined with console IO. There are no real operating system features being exposed by your code. At best, it is a "menu driven application." Operating systems provide an application execution environment and realize the necessary abstractions between the hardware/devices and the application(s). At a minimum, one would expect some notion of tasks or processes and your code does neither; at least as far as I can tell with a quick glance at it.

If you truly want to make your own "operating system," which is perfectly fine, you will want to consider some kind of layered approach that separates functional layers rather than intertwines them together.

Any "real" programmer wouldn't be able to "add" anything to your "system" because it is incredibly disjointed and there really isn't any "place" to begin working on because there are no real "layers" only a seemingly random collection of "do somethings" that are not API-driven in any classical sense.

Does "while(f)" actually do what you expect? I've never seen any "operating system" ever do anything remotely similar to what you're doing or how you're doing it.

Hopefully this won't sound mean spirited or otherwise insulting; it isn't meant to be. Have you ever read a book on operating system(s) or design/architecture of any operating system...ever? That might be a "good place" to start if you really want an "operating system."

Furthermore, I'd probably avoid using "rar" to archive files when using the .zip file extension. At a minimum, it suggests to other users on the Internet to avoid your file(s) because it isn't what is says it is and may be a virus or other malicious entity. I didn't look at the contents of the rar file, so maybe there is something "useful" with respect to operating systems in it...though from the code above, I'd find that rather unlikely.

None of this should be taken as an attack or insult to you; rather, hopefully, it will serve as a "wake-up call" to better consider/define what it is you really want to accomplish and to have you "take a step back" to consider the "world" as a whole, particularly in terms of WHAT an operating system *usually* does/provides in relationship to the hardware and application(s) so that you may eventually work toward a similar goal--if you really want to call this code an OS.

Writing an OS is non-trivial. OSes provide services and, probably most importantly, a set of "system calls" that enable applications to make use of those services. The system calls tend to range from incredibly rudimentary to relatively encompassing depending on the complexity of the OS and the features that it provides. Some very simple OSes do relatively little. Complex OSes like Windows, DOS, Linux, Mac OSX and numerous others do relatively A LOT.

Whatever it is you're thinking about in terms of "GUI" or other "UI," maybe that's what you'd really like to do and are simply using the wrong terminology? Whenever someone #include's conio.h and dos.h, real programmers cringe. While it is likely an interesting pursuit in the world of obsolete operating systems, tools and user interfaces, it has very limited practicality except perhaps from gaining the lessons learned from those who "been there and done that" so many years ago. If you're seeing an opening in the job markets for DOS programmers, I'd say that you're as likely a candidate as anyone currently deploying for that market because both are nearly brain-dead in terms of being suited for any reasonable task. Possibly if you had a rather unlimited number of 20MHz i386-SX PC-104 boards; each with only 1 MB of RAM, one could almost present an argument in favor of considering DOS a viable alternative for whatever control software we would expect to find such a world. Most of us would find it incredibly difficult to justify the power expense compared to a $2 16 or 32-bit PIC or ARM micro.

Since it seems that you are truly a beginning programmer (and all of us had to start somewhere), I'd strongly recommend that you use an updated compiler. There are numerous free ones available. If you find yourself using DOS as the underlying operating system (the OS part of DOS actually stands for Operating System), and you want the graphical capabilities afford by Turbo C++, I suppose that you can invest your time in that space.

I'd suggest that you decouple your code using appropriately named and defined interfaces. I find it incredibly hard to believe that any "OS" would have a function named 'e' or 'w' and that either of those would be "useful abstractions of the hardware to the application execution environment."

I would also suggest that you stay completely away from the C++ language and move to the C world...and not because I'm a C bigot when it comes to OSes. I've written a couple of operating systems in C++, the last one in 1996 before the then emerging eC++ standard came out. I don't think that anyone has even updated that standard in at least a decade...and those architectures that do support a C++ compiler tend to feature more capability than even the standard attempted to realize.

If you find yourself desirous of using C++, then you should actually take a few moments away from your busy schedule to learn C++. What you've presented in code by way of this forum (without considering the archived content), is explicitly not C++ in any reasonable kind of way except in terms of "requiring" a horribly obsolete and now non-conforming compiler. None of the "attributes" of a "well-written" C++ "program" (much less operating system) exists in the code I've seen in this thread.

If you find this insulting, please consider that it is nearly equally insulting for others to present code as being C++ when it is hardly better than a complete novice approach to the language. That by itself is "not bad," but this isn't C++, it isn't an Operating System, it isn't a GUI and there is no fundamental purpose for a "mouse" or anything remotely approaching what you seem to seek excepting "update" is definitely required.

I'd suggest that you start with your tools. If you need to execute from a Windows-base platform, then use MinGW or Cygwin or any of several free versions of tools such as the Microsoft educational-used tools.

Befriend google and start searching for content on operating system fundamentals. Consider:

http://www.cise.ufl.edu/~chow/sl1.pdf/

See page 3 for a nifty figure of the relevant layers of an OS (Windows NT, in this case).

There are practically an unlimited number of areas that you can research in the field of operating systems. Just the topics of scheduling algorithms fill volumes; I know, I own probably a dozen or more titles on the subject and there are probably dozens more that I won't/haven't purchase(d).

Most of all, good luck to you; we're really here to help, but you need to give us something to work with. You seem like you're trying to apply a few lessons learned about "coding" rather than taking the necessary time to really understand why we code and how we do it so that it isn't really and ugly collection of crap that is barely garbage in and garbage out. If you find that insulting, hopefully it will motivate you to engage yourself in learning what is "good" about what I've presented here rather than simply become annoyed as it seems so many others do...I call it Inspiration Through Attrition. Weed out all but the most stubborn seeks of truth in computer science...or something similarly as noble an endeavor?
