That clears things up.
You won't be able to install the iso image unless you can burn it to a DVD or usb. USBs are better since you can rewrite to them. The image is 1.3GB big which means you can use a 2GB flash drive (usb), burn the image to the flash on your fedora system and boot your fedora system using the usb drive. From there you can install Zorin 6.
There is another way to install from the image without burning it to a drive, is to use PXE boot from a network server. This is more technical and something I am still mastering....LOL
If you can find a 2GB usb drive, then you are in business.
