So you’ve got yourself an ISO and you want to turn it into a thumb drive. Sure, you can hack that thing together yourself.
Or you can use unetbootin. It’ll whack out a USB thumbdrive running a handful of Linux distributions and bootable utilities such as Parted Magic, Ophcrack, Gujin, or Freedos. All automatically downloaded for you after choosing a couple of options.
Even if you’ve got an ISO image that you need to load up onto a thumbdrive that isn’t included in the list unetbootin should be able to handle it. The more you know!
