multiboot system setup keeping c: as system volume for all os

Hi all,
I am redoing my laptop for personal use as well as a standby in case of emergency. What i want to do is to setup a multiboot system which keeps C: for the system volume and hides the partitions for all other operating systems other than the one i am currently in. if anyone can please provide an insight into how to go about this or better yet walk me through the process of how to do it i would be appreciated. all help welcome on this topic. the operating systems i want to multiboot are windows xp, vista, windows server 2003, windows server 2008 and ubuntu. the notebook is a toshiba satellite p200s04 (PSPB6A) with 2 hard drives.
