I doubt you will find anyone who will rewrite your config for you, 
unless they are all nicer then I am..

I see, what I believe to be are several errors with your setup, which 
would probably cause your problems.

In your 3.86 example, you use 'label nu2' repeatedly. I believe labels 
need to be unique, and shouldn't repeat. I also believe label should not 
have any spaces in the name (I remember seeing some noise on this, I 
honestly don't remember if spaces in the label name are accepted).

In all of your examples, you repeat 'menu default'. I again may be 
wrong, but I believe you may only use that once per menu (file).

I could be wrong on all of this advise, I haven't updated my pxe stuff 
in about a year, but I would start there to see if it improves your 
situation.

Lastly, I believe the syntax hasn't changed between 3.8 and 4.02, but
due to code base changes, It may have become stricter.

Please try correcting per my suggestions, and report what problems you 
are having, as you may get more help that way.
