I have W7 installed on my 'C' drive and I have a 'D' partition that I would like use for Vista. Can I just install Vista and point to the 'D' partition? Do I need to install Vista first?
no need for such...u can even install win7 first too...then go to system panel,advanced properties and chose ur Primary OS and u r set to go...both vista and 7 have this option.
