Hi Everyone,
I've been looking all over the net and on the forums here and I can't find a definitive answer to my question, so here goes:
Can I safely perform a clean install of Windows Vista on my Secondary Hard Drive (D

without erasing the folder structure there for a dual-boot with an XP 32bit which is currently on C:? I have program installations, some music etc. stored on D: and I don't have the space on C: to move them there to completely erase or format D:.
I know for a fact that I can do this with an XP installation (because I've done it before) - I just told it to install to the formatted partition and it just created the necessary files in the root directory and the \documents and settings\ and \windows\ subdirs.
I really hope windows vista 32bit can do the same. Can someone who has done this or knows for a fact confirm that if I just tell it to install to a formatted partition it will only create the new folders (windows\ and users\ from what I've seen elsewhere) without erasing anything else?
Also, is it just as safe to launch the clean install over D: from within windows or would you recommend booting from the DVD?
How about 64bit (I'm also thinking of a triple-boot with another hard drive - XP, Vista 32bit, Vista 64bit)? It should be the same with 32bit but has anyone encountered anything different?
I'm using Vista Business btw.
