You don't just download the image, it has to be written properly to the USB drive (or a DVD as well) in order to use it as a bootable device.

Assuming you wrote the image properly, did you boot from the USB drive to begin the install process? Sometimes, you have to manually select the USB drive depending on the boot options already set in your BIOS.I used a usb drive
