Bootable USB flash drive tutorial

Introduction

Quite often we need a bootable storage medium (CD, DVD, USB flash memory or memory cards).

Whether we are installing an operating system (Windows, Linux, Chrome OS, etc.), whether we need a deviruser, recovered or lost passwords, if we have the iso image of that program, we'll create bootable media with the help of simple programs.
Below, I will present 2 of the most widely used free programs for bootable storage media. Since CDs and DVDs are not much used, we'll discuss Rufus (for USB flash bootable) and Etcher (for memory cards and USB flash).


Create a bootable USB flash drive with Rufus

First download the Rufus.exe program. It does not install, but it runs directly. Connect the USB flash to your PC and start Rufus. It looks like this:


Rufus

I used an 8Gb flash USB. Using the search button, you choose the iso file we need and that is saved on your PC (in our case a Ubuntu distribution).


Rufus

Now, press the Start button and within minutes, the USB flash will be ready. If we now connect it to a PC off, and it is set in bios to boot from USB, when it starts, it will start installing the new Ubuntu operating system (be careful that the old operating system will be erased and can not be recovered).


Create a bootable USB flash drive or bootable card with Etcher


First, download the Etcher program. After installation, connect the storage medium (USB flash drive or card) to your PC and start Etcher. The window opens:


Etcher

Select the iso image of the program to be copied to the storage medium (in our case, the entire distribution of Ubuntu and USB flash of 8Gb). The following window will appear:


Etcher

Flash button is pressed and within minutes the bootable media is ready.
