How to Create a Bootable USB to Boot the PC

For a long time the means used for the installation and startup of an operating system have been the CD and the DVD. However, today most computers no longer have these types of readers. And it is that the arrival of USB storage devices with high read and write speeds has made them become the media used today. In this way, it is currently possible to take an operating system wherever we go or to boot the PC from a USB without problems. We will show how to create a bootable USB for an operating system in a very simple way.

These types of devices are what we know as bootable USB or bootable USB. Now, what exactly is it and what do we need to be able to create such a USB?

What is a bootable USB and what is it for

Given that bootable comes from the English word boot, which means boot, we can say that a bootable USB is a bootable USB . A USB capable of running on a PC without having to have an operating system installed and that allows us to boot the system on any computer or even ours if it is damaged.

Now, for this we will also need an ISO image of the system. A file where the exact copy or image of a system is stored. With the USB device and that ISO image ready, all we have left is to use software that allows us to create a bootable USB.


While today there is no problem of finding high capacity USB drives, which offer high speeds and at a good price, the truth is that it is also important to make a good choice of the software that we will use to create our boot media.

If what we want is to create a bootable USB for Windows 10, it is important to know that Microsoft itself has its own tool. This is the Windows Media Creation Tool, which, as its name implies, has been designed to create installation media for Windows and will make the task much easier.

The first thing we have to do is download the tool and then open the executable file that has been downloaded to our computer. From there:
