Convert a Nero Image File to ISO
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.
How to Convert a Nero Image File to ISO format
The conversion command is as follows, be sure to replace the path to the appropriate nero image file and the appropriate output path:
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?
If you know of another way to convert nero disk images to iso or other formats, do let us know in the comments. This is pretty efficient though and requires no usage of outside tools, so it’s pretty nice.
