How Do You Make A Bootable USB Drive

Today we are going to see how to install an operating system when you don't have a CD or DVD drive on your computer. This article provides a step-by-step guide for installing Windows 10 on your computer.  Most modern laptops now come without optical drives. The main reason for this is that these optical drives are very bulky and take up space. Because of this manufacturers don't include optical drives. However, this poses a challenge for the amateurs, for whom it can be hard to install an operating system. Luckily, there are many software tools for installing Windows. Now, we are going to learn how we can use a regular USB flash drive to install Windows 10.  For this, we are going to use a utility called Etcher. It is a free and open-source software that allows us to prepare our bootable USB flash drive easily. 

Before we begin, let's talk about the meaning of that oft-used term "booting" as this will help you to understand the process a little bit.

Booting is a process that takes place immediately after your computer is turned on. It includes scanning of main components and checking memory. If everything goes as it should, the operating system will boot. With a modern computer, the whole procedure takes only a few seconds. 

  1. Normally, the computer is set to boot automatically from the primary system disk. For example, if we need to use a USB flash drive for booting our computer, we will need to change the boot order of the bootable devices. So first, let’s do that.
  2. After starting the PC, quickly press the F12 key, which will bring up a menu with the selection of disk drives. Select the USB flash drive and press Enter. Once done, save settings and restart your computer. Now we can start the actual process of creating a USB flash drive.
  3. First, download Etcher and install it in your system. You can download it from its official website or GitHub repo.
  4. Download the ISO file from a trusted source. If you are going to install Windows 10, you can get the ISO file from the Microsoft website.
  5. Now plug your USB flash drive into your computer and launch Etcher.  It will automatically detect your USB flash drive and select it by default.
  6. Locate the ISO file using Etcher and click on “Next” to start the process. When you do that, you will receive a warning message saying that your device data will be erased completely. If you haven't made a backup yet, now is the time to do so. This process will take roughly 3-5 minutes. After the process has completed, you can eject the USB flash drive and use it. We hope this helps.
