Installation media have an error by default

Hello. I download netrunner-16-dvd-64bit.iso with md5sum 8901d3f4eff754fe2bf3d59d8cf63e2a and it seems to have a build in error.
How to reproduce: dd the installation media to a usb-pendrive. Start computer and at the countdown select the function to check itself. It always reports an error. I have tested 3 different usb-pendrives and twice the md5sum.
