1) Did you buy windows 10 or trying to upgrade to windows 10.

if the first 1) Why buy it when you get the upgrade for free and 2) how did you make the USB drive?

if the latter then 1) you HAVE TO UPGRADE WINDOWS 7 FIRST WHILE IN WINDOWS! Then once it is upgraded to 10 you can do a Clean install. Doing a clean install before updating it WILL NOT GIVE YOU A UPGRADE!
