There are many different ways to create a bootable USB drive both on Linux and Windows. The method I prefer is using a Windows program called Rufus, I find that it is the easiest and most reliable method of all of the different ones I tried. You can obtain Rufus by going to https://rufus.akeo.ie/. To make a bootable USB do the following steps:
After starting Rufus use the device drop down menu to select your target USB drive. If you only have one USB hooked up to your computer it will default to that drive.
Click on the disk icon next to the ISO image drop down menu which will pull up a explorer window and select the ISO image you want to use. Select the .ISO image file then click open.
The partition scheme and target system type, file system cluster size and new volume label settings are determined by the .ISO image and should not need to be changed unless required by you. Click on Start.
You will then get the following dialog box. Click OK to begin the process.
You will get a warning message below. Make sure you are using the correct device and then click OK.
The process of creating the bootable USB will begin.
That’s all there is to it, when the process finishes you will then have a bootable USB drive!
