So, to proceed without verifying the image, from terminal, type in this command: sudo defaults write com. Then try to install the system, if this does not work again, you can start the installation without verifying the image, but you should really trust the image you're using from being corrupted or modified just to make sure the download went right, use the SHA-1 code to make the file has been downloaded right.
