Q: How do I run an earlier version of OS X (Leopard) on my Mac that runs on Yosemite?
I recently came across a circumstance where I needed to run OS X 10.5 Leopard or 10.6 Snow Leopard on my Mac, but I want to keep OS 10.10 Yosemite as my default. The closest I came to solving this problem was partitioning a new drive on disk utility and installing the operating system on the new drive. The only problem is that you can't install any old software on Yosemite and It stops you from even opening the OS X installer.
How do I "dual-boot" an older version of OS X alongside with Yosemite? Please help!

That is not "dual boot." And, that Mac cannot boot from anything earlier than Yosemite.
The only way to virtualize Snow Leopard would be to use Snow Leopard Server (US$20 on the retail web store). That is the only version that is licensed to be virtualized. All of the legitimate VM software honors that license agreement and won't virtualize the non-server version.
