How to converte DMG extension to ISO using PowerISO :
I)- About ISO & DMG extensions :
The DMG format replaces the older .IMG file format used in Mac OS Classic. DMG disk images can be opened using the Apple Disk Utility that is bundled with Mac OS X on Apple computers.
DMG files are Mac-specific and are not intended for use in Windows. However, Windows Daemon Tools may be able to mount virtual drives from some DMG image files. Other utilities may also be able to convert DMG files to a format that can be recognized by Windows.
An ISO image is an archive file of an optical disc, a type of disk image composed of the data contents of every written sector of an optical disc, including the optical disc file system.[1] ISO image files usually have a file extension of .iso. The name ISO is taken from the ISO 9660 file system used with CD-ROM media, but what is known as an ISO image might also contain a UDF(ISO/IEC 13346) file system (commonly used by DVDs and Blu-ray Discs).
ISO images can be created from optical discs by disk imaging software, or from a collection of files by optical disc authoring software, or from a different disk image file by means of conversion. Software distributed on bootable discs is often available for download in ISO image format and, like any other ISO image, may be written on, or "burned" to, a CD, DVD, or even a USB flash drive with any capable software.
