Windows 7 with windows server 2003

I had dual OS , C: drive for windows XP and D drive for server 2003 installed,

I installed windows 7 on C drive again , now my Drive is formated and installed with windows 7, but my Server 2003 still has windows files,

now I only see windows 7 option not server 2003.
some one say me tha install EasyBCD to edit boot loader to solve the problem,

Can you guide me how i add windoser server option in startup so i can use my D: driver windows server 2003 version.

please write step by step process
