I want to dual my Macbook with Mavericks 10.9.4 and Kali 1.0.8. I have downloaded the Kali .iso and "burnt" it to a USB stick using the dd command from in Terminal. I have partitioned my hard drive and left 50GB for Kali. I want to boot from the USB to install Kali (I'm pretty sure this is the way you are supposed to do it). However, when I hold down the option key at boot time and select the USB, my MacBook freezes. I have read stuff on google about grub. I am supposed to use that to make it boot? What do I need to do to have a dual boot Mac/Kali system?
