Chosen Solution
Has anyone had any success running more than two partitions on a single hard drive? I would ideally like to run the latest Mac OS software but also have a partition to run Mac OSX Snow Leopard to use legacy Power PC applications and also run a third partition with BootCamp to run Windows 7.
Yes, I’ve run older MacBook Pro i5 64-bit 15" with 10.5, 10.6, 10.7, and 10.8 on the same time (quad boot). Note that OS X has a hidden partition or two. What I did was install one OS first, then create a DMG of it using DiskUtility and move it to a USB hard drive. I did this for each version of OS X, then I repartition the hard drive in to 4 partitions. I then use DiskUtility to restore each DMG to a partition of its own. When you then first turn on the Mac, hold down “Option”, and it will let you choose the bootable OSs. You can go to System Preferences –> Start Up Disks to choose which one starts by default. Note 10.5 and 10.6 run only older hardware and you need to install their latest combo updates for drivers.
