How to boot a USB? Have you had problems with your computer and need to reinstall the operating system (OS) or do you want to start programs without starting the OS? For these cases, the use of bootable or bootable drives, such as USB or DVDs, that have the ability to open and start programs on computers in which the OS has not yet been loaded into RAM is usually used.
Formerly, this was done with CD or DVD, but over time they have become obsolete and, although USB sticks or drives are also used less frequently today, they are the perfect option if we want to install software on an empty machine or if we want to install an operating system from scratch, be it Windows, Linux or another.
What is a booted USB
A booted or bootable USB refers to a removable boot drive that is capable of booting into the computer alone without the need for an operating system that opens applications. With a booted USB, you can execute functions that the operating system might not include, reinstall operating systems or even execute them without going through the installation process. To boot a USB, you usually need the following:
- ISO image of the program or file you want to open or run on the computer.
- Pendrive storage is clearly higher than the file you want to enter it (at least 4 GB onwards).
- Application that allows you to boot the USB. Next, we will see several options to achieve it.
Programs to boot a USB
There is more than one program that you can use to boot a USB, some are integrated into the operating system and others must be downloaded previously. These are some of the best programs to boot a USB :
- Rufus : is an external application that will allow you to boot a USB with ISO images. These do not necessarily have to be for Windows, as they can also be from other operating systems. The advantage of this program is that it works for all OS (Windows, macOS, Linux / GNU). It is translated into Spanish, is free and has portable versions that do not require installation.
- RMPrepUSB : also an external application, it is one of the most effective programs for booting storage units. It is possible to store more than one software in the same unit, as long as there is space for it and do not exceed the limit of 2 TB. Just like Rufus, RMPrepUSB is also free, but it doesn’t have a Spanish version.
- UNetbootin : This option is exclusive for GNU / Linux operating systems, although it can be installed on all other operating systems. It is one of the oldest ways to create booted USB and is compatible with Ubuntu .
There are other programs integrated in the operating system that you can use to boot a USB, then we will explain how to do it. Anyway, and whatever program you decide to use, it is important that you know that everything inside the memory will be deleted. For that reason, you will have to format the USB beforehand and make a backup to make sure there are no files in it that you can lose.
