So, you mean to say that you have two hard drives, one with Vista and one with 7 and you would like to dual boot between them, right?
If so, all the work is done for you! This is how to switch to your Vista hd:
1. Restart
2. Once you get to your BIOS POST Screen, press the button that it says to enter "boot devices" or something like that. It should be something like F8, at least that's what it is for me.
3. Select the hd that has Vista on it, press enter and enjoy your dual boot!
Any yes, I've done this. I had it going for my 7/XP hard drive and my OSx86 Leopard hard drive, until leopard MSODed (
Mac Screen Of Death). Well, I hope I helped!
