Today we are going to show you how to make a bootable USB drive to install almost any operating system. For this tutorial, we are going to use Windows as our operating system. To start this process you need three things. One is, the USB drive itself and the second thing is Win32 Disk Imager. It is an open-source software and therefore it is freely available to download from their website. The third thing you need is an ISO file of your desired operating system. By doing a quick Google search you will be able to find almost any .ISO file.
Connect the USB drive to your PC and drag the downloaded .ISO file into your desktop. Also, make sure that your USB drive has enough space to contain the OS files. Although the Win32 Disk Imager will automatically format your USB drive, for the time being, we recommend that you manually format the drive beforehand. This avoids difficulties when creating the bootable USB drive.
Now you are ready to start the bootable USB creation process. Install Win32 Disk Imager and open up the software by double-clicking on the icon.
Once you open up the Win32 USB Creator it will automatically detect the USB drive that is plugged into the computer. To avoid any confusion, make sure that you have plugged just one USB drive to the computer. If you have any valuable information on your USB drive, then now it is time to backup them. Because once the process has started there is no going back and your USB drive will get completely wiped.
Now start the Win32 Disk Imager and click on "Browse". In the window that opens, locate the ISO file that you just moved to the desktop. Once the ISO file is correctly selected, you will be able to see its name on the Win32 Disk Imager. Double-check to see if everything is right.
Now you can start the bootable USB creation process by simply clicking on the "Start" button. The Win32 Disk Imager now begins formatting your USB drive. After that, it will copy the required files. This will take a few minutes to complete. If the progress bar is not moving don't panic and close it because it damages the USB drive.
When the process is complete, Win32 Disk Imager will display a success message. After that, you can safely remove the USB drive from your computer. Then close the tool. Now your USB drive has been made bootable and you can install your desired operating system.
Restart your computer, enter the BIOS by pressing the key it displays when booting your computer. Now set your booting order correctly and restart the computer once again. If you have done everything correctly, you will be presented with a setup window of your operating system. From there you can partition your disks and continue the installation process.
