I finally gave up and tried to install on the HD in Bay 1 (drive 0), so I used bootcamp assistant to split the disk 0 (bay 1) that has my mac partition with a Windows Partition, followed the instructions for bootcamp and it worked as expected! No more errors. I tried every combination and workaround I could find (including those in this thread) and the ones on the various Windows support sites but nothing worked. I was planning to install Windows on the second drive but kept getting the 'Windows cannot find system volume.' message. I have the exact same problem, I got a new 8 core Mac Pro with 2 HD. Oh wait, I should expect no less from them. Then I tried deleting the big partition, but it won't say Unallocated Space, and if I try and reformat then I get an error. about this error message, but in their work-around, they want you to click 'New' in the Advanced Options, and my 'New' is grayed out. The latter is the one I keep trying to format and install, but can't get it to work.

(Bay 2 is empty but I'm saving that one for a future audio/video drive) The Installer shows 'Disk 1 Partition 1' at 200MB (for the Boot Camp partition) and the 'Disk 1 Partition 2' for the rest. I am trying to install it onto a completely separate internal drive, located in bay 3. Has anyone figured this out yet? I tried installing Vista Ultimate 64-bit on my new 8-core Mac Pro, but I too am getting the dreaded 'Windows is unable to find a system volume that meets its criteria for installation' no matter how many times I reformat the selected partition and reboot.
