 In Win98, you can start Windows from the DOS prompt with WIN. This does not seem to work in Windows 2000. Does anyone know a way to start Windows at the DOS prompt?

No can do!  Unlike Win98, which is build upon DOS (regardless of what Microsoft said...) W2K does not use, run, or even include DOS.  In fact, W2K and DOS are mutually exclusive at RUN TIME.  DOS is a 16-bit mode application and W2K is 32-bit mode ONLY.  These two don't mix.

You may say, "hey, I've run DOS 16-bit apps in W2K in the DOS shell."  Well, you might say that but you'd be WRONG.  The W2K CMD.EXE shell is NOT DOS.  It's a clever emulation using the X86 virtual machine capability.  As long as the DOS application is "well behaved" W2K can run it.  If it get out of line and tries to fiddle with the "machine" things break down since there is not a real "machine" for it to twiddle.

But to summarize your question.  There is NO DOS boot for W2K.  The only way to run W2K is to have it boot itself via its boot loader, NTLDR.

Can't do better than that--jhance is right in every detail.

I will differ slightly from jhance.  CMD.EXE is a 32 bit command shell, it is not an emulation of anything.  It does not spawn a virtual machine of any kind.  NTVDM (NT Virtual  DOS Machine) is the emulation of a 16 environment and it is spawned by COMMAND.EXE not CMD.EXE.

With that exception, jhance is right on.

I have found a better way to solve the overall problem than starting Windows 2000 from DOS. I therefore have no need to run Windows 2000 from DOS, and am deleting htis question.

Just because you don't like the answer doesn't mean it is any less correct.

You asked a legitimate question and a legitimate answer was posted.  I believe you are obligated to conclude this question rather than delete it.

  The intended question, although not stated exactly this way, was "How can you start Windows 2000 from the DOS prompt?" I do not consider "It cannot be done." an answer to this question. Besides, since I cannot test the answer "It cannot be done," the way I could test a solution, I have no way of knowing that this answer is correct.
   I feel that nobody has answered this question, and I now find that I no longer need an answer to this question. I have therefore withdrawn the question.

"It cannot be done" is a valid answer.  Often knowing that something is not possible is of great value.  It keeps you from wasting time on something that cannot succeed.

If there WERE such a way, some other expert here would have pointed out my error and you'd have an alternative.  As it is, my comment was confirmed by others.  

There you have it!

<<"It cannot be done" is a valid answer.>>

   I simply do not consider it an answer to my question, and I still cannot be sure it is right. I sometimes find answers to questions that the "experts" say cannot be solved.

Leithauser,
Your initial question was answered.  Due to the fact that all details were not provided in the initial question, IMHO Jhance gave you an "A" answer.  What I am going to do is refund your points, accept my comment as an answer.  I will than make a question for jhance in this topic area.

Thank you

Well Leithauser jhance is 100% correct. It can't be done. End of story. Just because you think it can does not make it so. "It cannot be done" answered your question which was "Does anyone know a way to start Windows at the DOS prompt". Whether you like it or not It cannot be done. Geesh jhance even explained to you why, which is DOS does not exist in Win2000.

"Does anyone know a way to start Windows at the DOS prompt"
