In dos, what would be the path for making a directory and copying a directory or folder from a cd?

Do you mkdir and then name it? Do you mkdir c: ???

For copying, do you change directory(cd) to that directory? and then copy from the cd drive D like this:
D: copy 1386 c:\windows2000
That's if I made that particular directory.

I want to do an install of 2000 or XP thru dos or at least start with dos to copy the files to the hd first.
Anyone know how to do that?
I also want this to be a dual boot with 98.
I am only doing this as a learning project.
