Preliminary operation

Before getting into the tutorial and going to find out how to create bootable USB, there are some preliminary operations that you need to do to make sure everything runs smoothly.

First of all, you must make sure that you have at hand the "material" necessary to carry out the operation described in this guide.


  • A USB stick of at least 4GB - to create a bootable USB stick with Windows, macOS or Linux you must have a pendrive with at least 4GB of free space (if you don't have one yet and want to receive some "tips" on which to buy, read my guide to purchase dedicated to pendrives). Also make sure that the pendrive to be used is empty or that in any case there are no important files on it, as it will be necessary to format it to make it a bootable drive. If the pendrive is full and you want to avoid losing any data present on it, you can consider making a backup of your data, as I explained to you in my guide on the subject.
  • A good Internet connection - considering that you will have to download the operating system installation files to copy onto the USB stick and considering that these are very “heavy” files, having a stable and fast enough Internet connection is essential. Obviously, I am referring to a connection for the landline and not pay as you go. To test the speed of your line, you can follow the instructions contained in my tutorial dedicated to the subject.
  • Correct BIOS / UEFI configuration - to use the USB sticks created following this tutorial, you will need to correctly set the BIOS / UEFI of the computer. For example, to install Linux and older versions of Windows (as in the case of Windows 7 32-bit) on a recent UEFI-based computer, you will need to go to the latter's settings and disable the function called "Secure Boot" which prevents unsigned software from running. In other cases, however, you will have to activate the mode called “legacy BIOS” which simulates the use of the old BIOS on UEFI-based PCs (UEFI is an evolution of the BIOS if you don't know it). Also, in the unfortunate event that the operating system installation stick fails to boot, you will need to enter the BIOS or UEFI settings and set the USB port as the primary boot drive. For further information on all these procedures, consult my tutorial on how to enter the BIOS: there you will find everything explained.
