I'm currently running FS9 and FSX under XP-Pro.If i install Vista on another partition, will i get a choice at bootup?

yes you will. It will ask you to choose between XP or Vista.I have tested such a configuration and it runs fine.Pierre

many thanks Pierre

There is also a nice util named VistaBootPro which is helpful in adjusting the dual-boot behaviour after you get Vista/dual boot installed.scott s..

I have just done that. I had Vista32 and installed XP, on a SATA internal HardDrive too. (same disk, seperate partitions)I did this mainly for music creation as my pro soundcard has no V32 drivers yet, but I did not try out FSX on the XP yet, as I do have drivers for the Audigy 2Z that I use for FSXI am cautious though, there might be interference in the way document folders are laid out... interfering or deleeting files in the other OS ???? Not sure.... Anyway do a Google search for your particular type of installation, there are loads of examples and instructions for you.So far, I have stayed in Vista32 because it is prettier, and having a quad core CPU and 4 googligoos of RAM I don't think I need XP anymore.(only a 8600GTS cause Im waiting for the 9800s)With UTX for USA I do not get the blurries anymore and texture is focused quite far ahead and behind, clear highways/interchanges, with lots of road traffic....allen
