NRG to ISO/DMG (please help)

[jonaseriksson]

Hi

I've downloaded a .nrg (nero disk image) to use with Parallels (its windows xp. i have legal key via a msdn subscription but no way to download the iso of the site since its done via a downloader(.exe)). Parallels however wont mount the file. Last time I had a similiar problem I managed to convert the file to .dmg, but I cant find any way to do that with .nrg files.

Anyone?

You need an ISO if you want to manipulate or burn it on a mac. BINs also work.. as well as the zip variety. You're probably going to have to download another file unless you can find a Windows machine to open it. If you could then it'd probably be easier just to download from MSDN though...

Assuming the NRG is just a single session ISO CD image, you can just remove the first few kb with dd from Terminal.app

dd if=image.nrg of=cdrom.iso bs=512 skip=600

Why skip 600bytes?

Why skip 600bytes?

'cause that's all Nero AG added to the ISO to make it an NRG.

I skipped the first 600bytes on a nrg DAO image and it couldn't mount in leopard.

Probably because it's not just an ISO. What's supposed to be in the image?

Hi, how exactly do I use Terminal.app along with this code and my dvd.nrg? Any help would be really appreciated.

How to use the dd command with Terminal

Hi, how exactly do I use Terminal.app along with this code and my dvd.nrg? Any help would be really appreciated.

Go to applications / utilities
Double click on Terminal to open up a terminal window.

From this commandline simply type the dd command as shown.

This will copy the .nrg file to the .iso file skipping the number of bites after skip=

how do you know how much of the file header can be removed?

Now it seems not to work anymore. The iso is not regconized.
