A bash script that's able create a boot-able USB out of ISO. It has a feature to automatically select USB drive if there's only one mounted. It will prompt you if there are multiple USB drives.
BootISO is very easy to install in your system. Just download it and paste it in /usr/bin
folder. For now, we'll use command-line instead to install it to simplify it.
# We'll download the file into this folder
cd "/usr/bin"
wget "https://git.io/bootiso"
