install the oldest os first and the latest os last. i know that's the rule for dual booting. but i got another question. my C: is bigger than D: and say i want the latest os been installed in C: right? (assume that i am too lazy to change the primary master and slave and bring the bigger drive to D

.
can we install the older os to D: and then install the latest os in C:?
that's my simple question. anyone tried it out before? thanks.
if anyone havent i will try it out myself and let u guys know...
