Nero nrg iso image file

Select the File menu, then the item Burn image. Ask for displaying all
files (*.*) since Nero expects files with the NRG suffix, locate your
image file and load it. Answer OK to the Foreign Image File prompt (if
Nero doesn't recognize a true ISO image).
You then have to specify the parameters of the ISO file (this holds
true for HFS images): Type of image: Data Mode 1. Block size:
2048. File precursor and image trailer: 0 length. No Scrambled and no
Swapped.
If the program complains that there are errors in the image file,
click on the button "Ignore" and launch the burning.
This information was found on the on-line help pages of Ahead/Nero's site.

Can Nero burn ISO images?
Nero can burn images of type ISO.
In the current Nero version the parameters of the ISO file still have to be entered.
Type of image: Data Mode 1 (assuming that it is a Mode 1 image)
Block size: 2048 Bytes (corresponds to the sector size of a Mode 1 image)
File precursor and length of the image trailer: 0 Bytes (assuming that the image file only contains ISO data and not other special information has been entered)
no Scrambled (i.e. it is not an image which was especially created for old Philips CD Writer )and no Swapped (assuming that the files contains the Bytes in the correct order.
The settings are based on the assumption that it is a normal ISO Mode 1 image file. This can be checked by opening the file with a Hex Editor. For File-Offset 08000hex (corresponds to Block 16 where the ISO ([p]rimary [v]olume [d]descriptor is saved). If there is a text there such as "CD001", then burning with the above mentioned method should work.
