firstly, before i get help on dual booting the OS's, quick question.

When i go to install OSX Yosemite by itself, on my main harddrive, it says this disk cannot be used to start up your computer?? any solutions???

and my second question, if my first question is answered, how would i go about splitting hard drive space and installing Yosemite on the second partition?

thank you.
