Netbook and other computer devices like the Apple Air may have either limited hard drive space or no CD or DVD drives to install certain files. An ISO file, which can be an operating system or other large file, can be transferred to an USB drive to install to your device. Your USB drive must be bootable before an ISO file can be extracted and transferred to the USB drive. A bootable USB drive means that certain programs will run and install once the USB is connected to your computer.
Install software that will allow your USB drive to become bootable. For example WintoFlash is a portable software that will automatically extract any ISO files once loaded to your USB drive.
