Adding a system image for your operating system.

Now that you are done with creating the bootable flash drive. It’s time to add a system image for your operating system. Create an empty folder and give it the name of your operating system or name it something else apart from new folder. By the way, naming depends on your choice. Extract the files of your operating system from an ISO format into an empty folder that you created earlier on. Once the files are done extracting, copy or cut the extracted files and paste them into the bootable flash you created. When the files are done being transferred, eject the USB flash drive. And once you plug back the USB flash drive you will be able to see the OS image come up.
