In case you need to convert Nero image file .nrg into regular ISO9660 .iso utility nrg2iso might be helpful then. It’s included into apt repositories of Debian and Ubuntu, so to install it execute:
sudo aptitude install nrg2iso
When it’s done, convert file by command:
nrg2iso image.nrg image.iso
Rather trivial task, right?

Except it often doesn’t seem to generate usable ISOs. Give it a try sometime.
Hi Downer,
Do you use nrg2iso 0.4 or earlier version? Download latest one here.
http://code.google.com/p/nrg4iso/
its non-compiled source code.
I don’t know how to compile it. gcc gave me some error.
Hi,
if it complains about unknown endianess and you’re using a x86 compatible machine, you can add
-DBYTE_ORDER=”LITTLE_ENDIAN”
to the CFLAGS in the Makefile.
Regards,
Patrick
this is a nice programm .. thank you
Crap…it says that the file is not a valid ISO9660-File. DAMN!
Thanks, it worked fine.
Very useful! thanks
I found this handy command from somewhere (I can’t remember where) which will mount a Nero Image:
mount -o loop,offset=307200 image.nrg /placetomount
It turns out that a Nero image is just a ISO with an added header so we just skip the header to so can mount it.
Thanks! worked like a charm…
i test version 0.4 and is working fine
8 nrg img converted in iso and all burned on cd working great
Thanks for the info i really needed it =D it worked great
funny when i try
‘nrg2iso image.nrg image.iso’ (without sudo) is says: ‘Segmentation fault’
anyway, works great whit sudo
thankx… gr8 job….
>> Crap…it says that the file is not a valid ISO9660-File. DAMN!
Exactly. I have had the same experience. Crap.

>> mount -o loop,offset=307200 image.nrg /placetomount
Sorry, this doesn’t work:
# mount -o loop,offset=307200 myfile.nrg /media/disk
mount: you must specify the filesystem type
or you posted without checking if it worked? [I am using Sabayon 5.o, an excellent Gentoo based distro.]
nrg2iso 1.0.1 just announces that my .nrg file is a Nero DAO with 1 session, generates a zero-byte .iso file and exits with no errors.
Wow. That was fast. Ubuntu 9.10
Simply just start reading your blog it truly is pretty informative i shall most definately keep an eye on your blog, you have turned me into a regular reader.Do you have a newsletter i could subscribe to ?
I’m pleased I located this site, I couldnt get any information on this subject matter prior to. Also operate a niche site and if you wish to ever interested in a little bit of guest writing for me make sure you feel free to let me know, im always look for people to check out my web site. Please stop by and leave a comment sometime!
i installed using apt-get
i typed in convert command the simple way ex: [nrg2iso image.nrg image.iso] and the detailed way ex: [nrg2iso home/compname/desktop/image.nrg image.iso]
both ways the terminal always says “image.nrg no such file” or ” home/compname/desktop/image.nrg no such file”
is there something i’m missing?? the .nrg file is a valid i checked it and i can mount it but i need to install this program via virtual machine so i need .iso file.
I noticed that Nero likes to name the default ‘Image.nrg’. If that’s the case for your source file, make sure your case sensitive I is correct, otherwise… ‘no such file’ good luck.

I am not really positive if best practices contain emerged almost things like that, other than I am positive that your big job is obviously recognized. I was questioning if you offer any membership near your RSS feeds because I would be extremely interested.
Is it okay to put part of this on my blog if I post a reference to this webpage?
A number of seriously beneficial information in this article. I was not really sure whether you are aware or not but it does appear your footer is overlapping a lttle bit. Must be a specific program within the actual code not really quite right. Nevertheless, good weblog you have got here and you definitely can’t beat wordpress platforms for a Website cms system.
I appreciate the time you positioned on this purpose or on this post. although u have fascinating ideas.fwerg

sudo apt-get install nrg2iso
Doesn’t work for me. First I get this error message:
mount: you must specify the filesystem type
Then I add “-t iso9660″ which gives other messages:
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog – try
dmesg | tail or so
Any idea of what to do?
Obviously I like your web-site, however you need to test the spelling on several of your posts. Many of them are rife with spelling issues and I find it very troublesome to tell you. On the other hand I will definitely come back again!
Hello everyone,
The problem with the NRG file it seems is that it is more than merely an ISO file plus header.
However, you can treat them that way if they are Disc At Once (DAO) written (i.e. the mount command, the nrg2iso (or the dd command) will all work just fine. However, when it is Track At Once written, NONE of the linux based tools will be able to convert the file to a usable ISO.
It may be possible to use some of the windows options through wine or a vm to do the conversion however.
Cheers
