I found a work around. The thumb drive auto booted to the UEFI version of the installer. I have a non UEFI install of Windows 10 installed. I think that is why it crashed. I was able to successfully install Ubuntu Mate with the traditional BIOS version of the installer. Someone should still look into this. Ubuntu Mate 16.04 did not have this bug.
