More systems these days are coming without optical drives (no CD, DVD, or Blu-Ray). Without the ability to boot from physical install media, how do we install an OS or boot into low-level system maintenance tools? This question is asked over and over again with a myriad of different suggestions provided online. Many suggestions are overly complicated or only work to boot specific tools / operating systems.
My favorite tool that aims to solve this USB boot problem in a more simple and generic way is “UNetbootin”. It is a GUI program that helps you make a bootable USB version of your install media or downloaded ISO for popular boot-disks. You can find UNetbootin and accompanying documentation on the project website at http://unetbootin.sourceforge.net/.
I hope you find this utility a useful addition to your IT tool-kit!
