Creating A Bootable Usb On Linux

Posted on Saturday 19th May 2018

In 2018 media such as CD’s and DVD’s have almost died out, with USB drives holding more capacity and being produced relatively cheaply. This means it makes more sense and is better value to use USB drives in place of CD’s or DVD’s.

This article looks at how to create a bootable USB drives for various uses.

What is a Bootable USB

A bootable USB is a USB attached media, which you can use as a boot device for a computer, this includes usb thumb drives and usb external hard drive enclosures.

How to do this?

1. GUI Tools

GUI Tools are programs which you run on your computer visually and are usually the easiest to use.


The simplest to use in my preference is UNetBootin (http://unetbootin.sourceforge.net/) which is available in most distributions.

All you need to do is:

2. Command Line

Using Command Line utilities is more complex but allows for more control of what you are doing and can get more information about what is happening.

- Insert the USB

- Find your disks path, (Usually it will be /dev/sdb1 but depends on what drives you have installed)

sudo fdisk -l

- Unmount the disk found above

sudo umount /dev/sdb1

- Using DD copy the .iso to the dsk

sudo dd if=/path/to/yourfile.iso of=/dev/sd1 bs=4M && sync

- Wait to complete then unplug
