First of all, did you check the md5 of the ISO you downloaded?

Grab a checker,

compare it to the md5sum for your ISO file here

if it matches then great. what tool did you use to make the usb ? this one?

format the stick, make another and when you boot it, at the boot prompt, choose verify installation media and it will perform md5 checks on the files.
