DMG files are a Mac OS X Disk Image files. like ISO files, DMG files are essentially disk images, which are intended to be used with the Mac operating system. The DMG files normally contain program installation files for Apple system and applications, but they can also be used to hold compressed files. With PowerISO, you can manipulate dmg files on Windows PC. PowerISO can burn dmg file directly to a CD / DVD disc. You needn't convert dmg to iso file before burning.

To burn dmg file on Windows PC, please follow the steps,

Simply changing the permissions on the DMG file will have no effect. Here is one purported solution that I have not tried myself, that uses the hdiutil convert command to make a disk image writable, and hdiutil resize to add extra space if required for any additional content.
