Etcher is a tool that helps you create a bootable USB flash drive from an ISO file. This tutorial will show you how to do this in Linux.
Bootable USB drives are a great way to try out a new Linux distribution to see if you like it before installing it. But you can’t simply copy an ISO file to a USB drive. Instead, you must “burn” the ISO image to the USB drive so that it’s bootable.
Etcher is software that allows you to easily create bootable USB flash drives to install or use operating systems.
Of course, there is always the option to use the dd command to create bootable media on the command line, but that’s still a pain even for the experienced user. However, in this tutorial, we’ll use Etcher to accomplish the task.
For those who don’t know about Etcher, it is a free, open-source USB bootable tool available for Linux. It has a beautiful user interface and was created by Balena.
Etcher help users quickly burn image files to USB devices or flashcards. It has recently become trendy in the Linux community.

Create a bootable Linux USB flash drive
Warning: This will erase the contents of the target USB drive. To ensure you don’t accidentally write to the wrong USB drive by mistake, we recommend removing any other connected USB drives before continuing.
1. Connect the USB flash drive to your system and Launch Etcher. Next, click on the “Flash from file” button. This lets you browse the ISO image you want to select for writing.
2. You will see the “Select target” button highlighted. Click on it.
3. Next, you need to select a USB drive to write this ISO file. Etcher finds a USB drive automatically, but make sure it has chosen the correct USB drive because if you have several USB drives connected to your computer, it might select the wrong one.
4. When you have done this, all that is left to create your bootable USB device on Linux is to start the burning process. To do this, click on the “Flash!” button. Then, Etcher takes care of the rest of the process.
5. Wait for the process to finish, and you should be done.
6. At the end of the whole process, you will see a window like this one.
Congratulations! That is it. The ISO has been burned to the flash drive successfully. Once Etcher alerts you that the image has been flashed, you can safely remove the USB drive.
Etcher is a user-friendly and reliable program to make a bootable USB drive in Linux. And it does this with impressive speeds times.
On top of that, it has a beautiful interface and works well. In addition, the process is pretty much the same when writing images on an SD card.
