 - Once confirmed, the flash will start and a small progress bar will appear showing the flashing progress.
 - After completion, the program will detect the OS from the iso and wish you a great time with your new OS. (Example: "Done! Have fun with your new Linux installation!)
 - **IMPORTANT**: Since dd needs sudo rights, ensure you have root priviliges.
