What is the best way to burn an ISO image onto a USB flash drive?


For some variants of Linux, UNetbootin does this without any extra configuration or work.


Depending on the ISO image, I recommend WinToFlash for anything Windows.

For Linux distributions, see Anonymous' answer.


You can use the dd command to "burn" an ISO image to a USB drive from the command line:

dd if=file.iso of=/dev/sdb

Change /dev/sdb to the mount point of the USB drive.

Be careful, as this will destroy the original contents of the USB drive.

Additionally, if the ISO is bootable (such as in installer image) then the USB drive will boot the same way.


Use 7-Zip and just extract the contents onto the USB drive.

When extracted, you'll see the same contents you would if you browsed to the disc.


You can't really "burn" an ISO image to a USB flash drive.

If you want a bootable USB from an ISO image, there are a couple of things you need to do

  1. Create a FAT32 partition on the USB drive (perferably, the first partition)
  2. Mount the ISO image to access its contents
  3. Copy the contents of the ISO image to the partition you just created.
  4. You need the SYSLINUX utility to make it bootable
