Hello,
 
Got two different errors in startup sequence.
 
The following error repeated about 12 times in boot up sequence :-
 
        Illegal mode for this track or incomplete medium
        The failed "Read 10" packet command was:
    Buffer I/O error on device hdd, logical block xxxxxx
 
The CD was verified after writing, and SHA checked.
 
Then later in boot up sequence we have :-
 
    Starting system message bus: Unknown group "netdev" in message bus configuration file
 
Though I should report these to the list.
