In the event that you want to install other systems on your computer, repair it or any other similar thing, you may need to use an image in ISO format to boot your computer from it and thus be able to achieve it. And, in this regard, although it is true that in the latest versions of Windows it is possible to mount an ISO file without installing anything, the most useful thing is usually to burn the image on an external medium.
Within this option, you can directly burn an ISO image to a disc (CD / DVD) without the need to install any program, but the truth is that if what you want is to speed up the process, or you do not have an optical drive in your computer, The simplest alternative you can use is to burn the ISO on a USB stick, and the easiest method is to use Rufus for it..
How to burn an ISO image to a USB stick in Windows using Rufus
In this case, there are three things you will need to be able to carry out the process: the ISO image you want to burn, a USB pendrive (we recommend No products found., which allows to speed up the installation and avoid problems), and finally Rufus software, available for download free of charge from its official website (You can use the standard version or the portable version without any problem).

Later, in the section of "Boot choice", you must select the ISO file to use from your computer, and all other options should be completed automatically, although you can alter the settings to your liking if you wish.
Finally, you will only have click on the start button and the process will begin.
