i don't have a lot of experience with multiple partitions, i don't really have a use for them. i'd like to try Windows 7 on a seperate partition. i have 2x 250 WD HDs in my computer, but i'd like to use my primary since it has Vista and the other is for storage only. also theres only about 60GB left on the storage drive while the main drive has over 100GB left. can i partition my Main drive in half, with Vista on one partition and Windows 7 on the other? will i get the boot choice in DOS when booting up?
