I can't share an ISO image. Like I said there is a lengthy process to getting new images created and posted to the web.
In what I was proposing I was meaning to check booting any other image that manually mount the partition using the "Disks" utility. This would allow you to fetch the logs out to further investigate where the problem you are seeing is.
You can look at the contents of the ISO by using "less" or opening it in file-roller on Ubuntu, 7z FM on Windows, or any tool that can look at the file listing on the ISO.
FYI I won't be able to check on hardware again myself until after the US holiday on my side.
