Return to Dual boot XP/Vista

I tried BCD 1.7 to (installed negrub and hide vista from xp so restore points would not be deleted) on my dual booting XP/Vista setup and it did not work. I am not concerned with it not working. I want to go back to dual boot setup XP/Vista. I tired several setting but I am only able to get either XP or Vista to single boot. I do not get a dual boot menu now. I have xp on C:, installed first, d:is a blank drive for files and I: is the Vista drive. E and F are dvd, G and H are removable drives.
Yeah, reset the bcd will keep only a single Vista entry, but returns everything to a working state for you to build upon.
