Did you try burning a DVD with the tool? If it doesn't work use ImgBurn at 4x speed.
The tool I use for making stick bootable when others fail is UltraISO Software To Create Bootable USB Flash Drive. Be sure to click the format button first, then Write.
if you should get the bootsect error using UltraISO then the stick may need to be wiped with Diskpart Clean Command to clear it of boot code which is blocking the write.
