[Help] I'll make an OS program

I'll make mine OS program and i need some help.

First; i need menü.It's just 3 page , non number page (Same IPhone menu) [o]oo
When i press left arrow key in page 1 , page 'll change and it 'll be page 3. oo[o]
And when i press enter select menu option.

Second; i need install cd. it's very basic but i dont know codes.
This code about of "Copy diskfile to computerfile".But i must work in disk,
because it's install cd :(/>/>


Example; This cd make it's:

Copy disk/a to computer/startup

Third; i dont know but if it possible i wanna make "user permission" so non user look programs.
When anybody write
# dir
it'll say "U haven't got permission"

First: I'm sorry English is not your first language, because it's a little hard to understand what you want.
Second: If I understand what you want, you want someone to write an OS program for you? I don't think that anyone is going to dedicate all that time if you haven't done anything. I know I wouldn't.

Code for install disk

 fs.copy("disk/a", "startup")

And like craniumkid22 said, nobody's going to want to write an entire OS for you if you don't do anything.

Ok, your English obviously isn't that good, I'm guessing you are Polish.

All of the things you need to know can be found on these forums, but you are unlikely to get anyone to write and OS for you.

Also, putting something in the startup file isn't the same as making an operating system for the computer. The computer actually loads CraftOS from the bios.lua file included with the mod, so it's that you'll have to be editing if you want to make a proper operating system.
