I partitioned a 64 GB USB drive to make a Kali Linux live USB, but it's not booting from my MacBook Pro. The command I used to write the iso into the partition is: sudo dd if=kali-linux-2017.1-amd64.iso  of=/dev/disk3s3 bs=1malsoThe partition I want to boot from is #3. Any insights as to why it is not booting?
