Convert a Nero Image File to ISO

Sep 25, 2009 - 3 Comments

terminal-icon-512x5122 Someone recently sent me a Nero Image File and I had no idea what to do with it, but after some looking around I discovered you can easily convert a Nero image File to ISO format. Apparently the only difference between a Nero Image File and a typical ISO is that Nero adds a 300k header to the normal ISO file. Using the command line tool dd we can trim this header and convert the the Nero image file to ISO format. All of this will be done via the Mac OS X command line so launch Terminal and enter the command as seen below.

Convert a Nero Image File to ISO format

dd bs=1k if=image.nrg of=image.iso skip=300

Essentially what this command is saying is that using 1k block sizes, from the input file of image.nrg (our Nero image that needs converting), create an output of image.iso (the desired ISO image file), after skipping the first 300k of the input file (aka the Nero 300k header). Works like a charm! Now you can burn, mount, or image the ISO any way you want, cool huh?

    Not familiar enough to understand how to run TERMINAL. Do I replace “if=image.nrg” with the actual file name i want converted and similarly replace “of=image.iso” with the name of the final iso file?
    Sorry and thanks for any help

    I keep trying to understand how to use Terminal and I have a better idea now however, when i try to convert using the Terminal Tip above: I receive an error message that says:”No such file or directory”
    So my new question is, where does the file i want to convert need to be located and how do i tell the Terminal where that is ?
    Thanks
