UPDATE: The 8.10 ISO-file was on the hard drive of that very computer. When I chose the ISO-file instead of the CD-Rom as source, the process finished without any problems.
My suggestion: Getting this error? Reboot and check the CD with the build-in CD-check and/or use the ISO-file as source (if somehow available).
