HELP - dual boot with ms-xp

[Ray Henry <rehenry-at-up.net>]

I need to shrink an xp install and make space for linux and EMC on a Dell PC. 
Dual boot using Grub or Lilo would be nice.  

I'm completely ignorant of how to do this and what effect it might have on 
the use of the MS recover disk when that other os goes to the hot place.

As the Beetles used to say, "Help me if you can, I'm feeling down /And I do 
appreciate your being round..."
