Install OS 10.4 on external drive using Yosemite
I have a Macbook Pro (late 2011) running Yosemite (10.10.3). I want to use LiveType and so I thought I could install OS X Tiger on an external drive and boot my mac from it. I have already formatted the external HD so I can install Tiger on it. However, when I restart my mac pressing C it won't boot from Tiger's install DVD.
I am at a loss here. Anyone knows if what I'm trying to do is even possible using a computer running Yosemite? If so, what is it that I'm doing wrong?
TIA
