How can I download a complete iso?

I have downloaded 13.10 in each variation using different browsers and even torrent. When I burn them to dvd or create a bootable usb, they won't boot from any machine. Each download has something missing.

Download from Ubuntu official release directory and then check if its MD5 sum is OK (from here), so you will know if the image is good or not.

To check the md5:

$ md5sum xxx.iso

md5sum is in the coreutils package, so if you don't already have it in the system:

$ sudo apt-get install coreutils
