Some guides on the internet suggest that it is possible to convert ISO disc image files (.iso) into an non-.iso image format (.img or .dmg) with hdiutil on OS X.

However, the manual page for hdiutil says that it basically only supports conversion into several UDIF formats.

Are images in the UDIF format bootable on non-Apple hardware? Wikipedia claims that UDIF, Universal Disc Image Format, is an Apple proprietary format, giving you the impression that it's not compatible with third-party hardware.
