(Forgive the basic question -- I did a search and couldn't find comprehensive answers -- most Google searches turned up OS86X stuff and most guides on here refer to partitioned HDD's) I just bought a mac pro and stuck a 1TB WD Caviar Black HDD into it. I'm going to run OSX off this hard drive, and I want to install Vista on the 320gb stock drive OSX came with. I've been a longtime Mac and Windows user, but I've never ventured into Bootcamp, so I really don't know anything at this point. From what I've been reading, you'd use Bootcamp to partition your hard drive -- something I don't need to do. I'm assuming I can just install Vista onto my secondary hard drive directly. Before I take the plunge and start pulling out my hard drives, I wanted to shoot off what I think is the right way to go about installing Vista 64-bit on my Mac Pro. 1. Format the 320gb HDD in Disk Utility to FAT32. 2. Pull out the 1TB OSX HDD. 3. Slide the #2 drive sled (320gb) to the #1 slot (<- is this necessary?) 4. Boot using the Vista DVD. 5. Install Vista, yadda yadda. 6. Put drive #2 back into slot #2, and replace slot #1 with my 1TB OSX HD. Questions: -- How do I switch between startup disks upon booting? I've read to hold the Option key at startup -- does a dialogue pop up asking me which disk to boot from? By default would it boot to OSX? -- Do I need to install the Bootcamp drivers? How would I do this (is it on my Mac Pro restore DVD)? I figured I should know exactly what to do before finding myself stuck without a computer.
