How to create a bootable USB Flash Drive with UNetBootIn to install OSX, Linux

Create Bootable USB Flash Drives


This is actually a pretty simple (and free) process. I re-posted the directions from BackTrack (a linux distribution of Penetration Testing Tools). FYI, I chose this method over using the standard Mac OSX Disk Utility primarily because Disk Utility does not accept ISO images. Also, UNetBootin support multiple platforms, making it a good universal tool.

This method of getting a live install to a USB drive is the simplest available using Unetbootin.
(Note that we will format the USB drive and erase its contents).

  1. Plug in your USB Drive (Minimum USB Drive capacity 2 GB)
  2. Format the USB drive to FAT32
  3. Download Unetbootin from
  4. Start Unetbootin and select an ISO diskimage
  5. Select your USB drive and click “OK” for creating a bootable USB drive
  6. Reboot. Enjoy!

Note: If you want to convert a DMG file to an ISO in the Mac Terminal:
