Etcher: A few years ago, the creation of one bootable usb it was not so easy. Years ago, CDs / DVDs were the main method of distributing operating systems.
In case of buying a new computer you would always have an 'installation disc', or if there was none you could create it through the operating system system.
Since then, however, things have changed and you can download any operating software online and easily create a bootable USB for any system you are interested in. Provided you have the right application to do it.
Let's see how it works very easily from any operating system
To create a bootable USB you need a disk image or ISO. ISO is basically a file that contains data that can be written to an optical disc such as a CD or DVD. It's basically an installation tray.
For Windows 10, you can download the ISO image via its installation media creation tool Microsoft. Για όλες τις distributions Linux, you can download the ISO you are interested in from the distribution's official page. You will only run into problems if you are trying to find some ISOs for working macOS because they are not readily available. For specific ISOs you may need to search for torrents.
Let's create the USB
Some operating systems, such as macOS, come with utilities for burning a disk image to a USB, but again, no. The utility of MacOS is a bit complicated especially if you are a beginner.
Today we will try something simpler.
The Ethcher tool is available for Windows, Linux, and MacOS. All you need is the ISO file and a USB. The application will take care of everything else in three simple steps.
After (easily) creating the bootable USB, you can use it to boot your computer from the USB and not from your operating system. In some cases, you may need to change the cm ordermovements from your computer's BIOS so that it reads USB first instead of your hard drive.
Download the application for your operating system.
Good luck…
