Vista - dual boot

hi everyone,

I have windows vista 64 ultimate install on my hard drive. i saw alot of
thread that is telling about dual booting with windows xp. My question is
that my 2 hard drives are mounting on sata-raid 0. i want to know is it
possible to install both system without destroying my raid. Can i install
both of this sytem by making a logical drive and a master boot or i must
destroy my raid configuration. I don't have any information I can suppress
so loosing my information is not a big deal. I could do a fresh installation
of those os. please let me know what the best solution.

Sincerely your's
