     To do this on Grub2 it was simple and it is not changed by normal 
events. What you do is edit menu.lst and put the item you to boot 
automatic in position 1, oh, excuse me it is position 0 now.

     No see above comment.

     Yes I know that. Also I went to the Grub web page and I entered a 
bug on grub2 which is that is almost impossible to manually change any 
thing and the Grub2 manual has zero examples of what to do.

     I can set the menu.lst to do almost anything I want. I have been 
using grub1 since 1995 and I learned real easy how to change grub with 
manual changes to menu.lst. This works because menu.lst can be added to 
by the system, but it is NEVER reset.
