triple boot

I currently have two versions of XP Pro running on my PC.
Drive C is the x86 version and Drive E is the x64 version. The drive is a 160G SATA drive partitioned into (2) 80G drives.
I have a new 160G drive totally empty (not even formatted) and want to install the Vista I just ordered.
I seem to recall something about the Vista install making changes to the C drive but can no longer find those warnings.
Is there a potential problem with setting up Vista on the empty drive or will it make changes to my current set up?
The current setup is running very smoothy and i don't want to mess it up.
thanks

Who is the Windows Vista BETA 2 for?
IT Professionals, Developers, Enthusiast, people who like to back up their data and try out new things and don't have issues just in case something goes wrong installing the software.
Make sure the drive is formatted as NTFS, the Windows Vista bootloader will be stored on C: and take over, you will still have access to your legacy versions of Windows under the Earlier versions of Windows entry on the new boot manager. -- -- Andre Windows Connected | http://www.windowsconnected.com Extended64 | http://www.extended64.com Blog | http://www.extended64.com/blogs/andre http://spaces.msn.com/members/adacosta
