dual booting xp and vista

Hi all, I partitione my hard drive for my laptop. I added XP first and got all the drivers an dhad XP working fine. I then added Vista, from recovery disks that I made when I bought the laptop. It wiped out XP.
I then installed a second drive and put XP in the second drive. The I reformated the first drive and added Vista to it. Now Vista works fine, but XP is missing the Boot Manager and won't load. Any ideas of what the proplem could be? Any ideas will be appreciated. Thanks for all your help in the past, hope you can help me again.
