In the early days, we used CDs and DVDs to install softwares on our computer. At that time, almost every OS came as CDs or DVDs. But today times have changed. Now many computers don’t even come with CD and DVD ROMs. Every software is available on the internet including OS. But you can not install operating systems on your computer like you install regular softwares. To install an OS on your computer, you have to use a special software to copy your ISO file to a USB drive. So to create a bootable USB, it is not enough just to copy the ISO file to the USB drive.
For this, you will have to find a USB flash drive with certain requirements. You have to make sure that your drive is formatted in FAT32 or NTFS format. You also can use exFAT format, if you are going to use the USB drive on a computer that has macOS. Then you need to ensure that your USB drive has at least 8GB of space to contain the ISO file. So to create a bootable USB, I am going to show you two options. First is, official Windows USB/DVD Download Tool by Microsoft and the other is Rufus by Pete Batard. If you planning to use your USB drive on low-level devices, you also can use a specialized software like Win32 Disk Imager.
Windows USB/DVD Download Tool
This solution is ideal if you are planning to install a Windows operating system using your USB drive. Windows USB/DVD Download Tool doesn’t support other operating systems. When using the Windows USB/DVD Download Tool, you will not be able to upload your own ISO to the software. But it has the ability to download the ISO file automatically within the software. It is an advantage over other programs because we will know that the ISO is up-to-date and that it is not corrupted. However, if you want to install other operating systems then this won’t work for you.
Rufus is undoubtedly the best program to burn an ISO file to a USB flash drive Unlike Windows USB/DVD Download Tool, It works with any operating system including Windows, macOS, and Linux. In addition, it is fully translated into all major languages. The most recent version of Rufus is 3.7 and it is available to download directly from Rufus official website.
Once you install and open Rufus for the first time, it will ask you to select a USB flash drive and the ISO file to start the process. All you have to do is, simply load the ISO file into Rufus and wait till Rufus to complete the process. If you have a computer with less space and don’t want to clutter your PC by installing softwares, then you can use the portable version of Rufus. It requires no installation and you can use it right away after downloading it. However, we highly recommend that you use the latest stable version whenever its possible. When compared to the other version, the portable version of Rufus doesn’t get updates that often.
