How make a dual boot with mountain lion and lion
Hello,
I used to use a dj software who doesn't work in Mountain Lion.
I have a Lion virtual machine but isn't the greatest solution because the compatibility between this VM and Mountain Lion isn't optimal.
So i have decided to make a dual boot and install Lion next to Mountain Lion but i don't know and i don't find how to do it so does anyone know how to do it please ?
MacBook Pro (13-inch Late 2011), OS X Mountain Lion, Turntables : Hercules DJ control Ai
