I've had no trouble with this before today, but have tried 7 or 8 times today with no success. I use Verbatim media, so I'm sure that's not the problem and I have tried various speeds, all resulting in failure! I use Nero to create the img file before using ImgBurn to write it. Below is my log. Thanks to anyone that can help.
