Triple Boot System

I am now running a triple boot system and have not had any troubles. It is running XP pro, Vista Enterprise, and Mandriva Linux. I installed XP first, then vista and linux last. Only problem is when i boot into xp it wants to run checkdisk on the vista partition. I have’nt let it run yet, just stop the check and everything seems fine. anyone want to try this and need help, just let me know.
