You can check an ubuntu iso image for errors.

To do this you need to know the "MD5" of the iso. If you take a look at you should be able to find a relevant MD5SUMS
text file. Simply look inside there and you will find a long number made up
of digits and the letters A to F.

Next thing you do is go into a terminal/shell window and, using the
filename of the iso, type in:-
md5sum path_and_filename.iso

Then compare the output of MD5SUM with the relevant line from your MD5SUMS
