2 Ways to Create an ISO from a Bootable USB in Linux

In this article, we will show you how to create an ISO from a bootable USB drive in Linux. We will explain two ways to achieve this: via the command line interface (CLI) and a graphical user interface (GUI) program.

Create An ISO From A Bootable USB Drive Using dd Tool

dd is a commonly used command-line tool for Linux and other Unix-like operating systems, used to convert and copy files.

To create an ISO image from a Bootable USB Drive files, first you need to insert your USB drive and then find the device name of your USB using following df command.

Sample Output

Filesystem Type Size Used Avail Use% Mounted on udev devtmpfs 3.9G 0 3.9G 0% /dev tmpfs tmpfs 787M 1.5M 786M 1% /run /dev/sda3 ext4 147G 28G 112G 20% / tmpfs tmpfs 3.9G 148M 3.7G 4% /dev/shm tmpfs tmpfs 5.0M 4.0K 5.0M 1% /run/lock tmpfs tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/sda1 vfat 299M 11M 288M 4% /boot/efi tmpfs tmpfs 787M 56K 787M 1% /run/user/1000 /dev/sda5 ext4 379G 117G 242G 33% /media/tecmint/Data_Storage /dev/sdb1 iso9660 1.8G 1.8G 0 100% /media/tecmint/Linux Mint 19 Xfce 64-bit

From the output above, you can clearly see that our attached USB device name is /dev/sdb1 .

Now you can run the following command to create an ISO from a bootable USB drive as shown. Make sure to replace /dev/sdb1 with your USB drive and /home/tecmint/Documents/Linux_Mint_19_XFCE.iso with the full name of the new ISO image.

$ sudo dd if=/dev/sdb1 of=/home/tecmint/Documents/Linux_Mint_19_XFCE.iso

In the above command, the option:

• if – means read from specified FILE instead of stdin.
• of – means write to specified FILE instead of stdout.

Once done, you can verify the ISO image using following ls command as shown.

$ ls -l /home/tecmint/Documents/Linux_Mint_19_XFCE.iso

Create An ISO From A Bootable USB Drive Using Gnome Disks

Gnome Disks is a graphical tool used to manage disk drives and media in Linux. It is used to format and partition drives, mount and unmount partitions, and query S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology) attributes.

If you don’t have gnome-disk utility on your system, you can install it by running the following command.

$ sudo apt install gnome-disk-utility #Ubuntu/Debian $ sudo yum install gnome-disk-utility #CentOS/RHEL $ sudo dnf install gnome-disk-utility #Fedora 22+

After successfully installing Gnome disk, search and open it from the system menu or dash. Then from the default interface, select the bootable device from the list of mounted devices on the left-hand pane, by clicking on it and click on disk options. Then click on Create Disk Image option as shown in the following image.

From the dialog window, set the name of the ISO file, its location and click Start creating. Then enter your password to open the bootable device and the process should start if the authentication is successful.

That’s it for now! In this article, we’ve explained two ways to create an ISO from a bootable USB drive in Linux. Use the comment form below to share your thoughts with us or ask questions.

10 Useful Tools to Create Bootable USB from an ISO Image

CD and DVD writers are a thing of the past. You are not likely to find them in modern-day laptops. If your goal is to create a bootable medium, then creating a bootable USB drive from an ISO file remains your best option.

There are quite a number of tools that can help you create a bootable USB drive. Some will even go further and let you create a multi-boot USB drive where you get to choose the OS that you want to install.

Here are some of the widely-used utilities for creating a bootable USB drive from an ISO file in Linux desktop systems.

1. Rufus

We start off our list with Rufus which is arguably one of the most popular bootable USB creation utilities. It’s a free tool that you can download and create bootable USB pen drives, memory sticks, etc. It is particularly helpful when you want to create a USB installation medium from an ISO image or work on a system with no OS installed.

Rufus is a portable utility that comes with a small footprint – 1.3MB only. No installation is required. You just need to double-click on the executable file to launch the UI and start creating your USB bootable medium from an ISO image of your choice (both Windows and Linux).

Unfortunately, Rufus is only supported on Windows and the developer has not yet ported it to Linux as yet. If you are looking for an alternative that works on Linux, read on.

2. UNetbootin

UNetbootin is a free and cross-platform utility for creating live bootable USB drives using an ISO image from all the major Linux distributions, even the lesser-known ones such as Tails, and AntiX.

It doesn’t employ distribution-specific rules for creating bootable USB drives, and therefore, most of the Linux ISO images should load without a problem.

Apart from creating a Live bootable medium, you get other system repair tools and utilities for example:

• Parted Magic
• SystemRescueCD
• Smart Boot Manager
• Dr.Web AntivirusF-Secure Rescue CD
• Super Grub Disk
• Backtrack
• Ophcrack

3. Balena Etcher
