Convert DMG to ISO Ubuntu - bootable disk

Quite a nifty piece of software in Ubuntu is DMG2IMG which converts DMG images to IMG (same as ISO).

Install DMG2IMG:

sudo apt-get install dmg2img

Convert the DMG to IMG:

dmg2img sourceFile.dmg

Convert IMG to ISO:

mv sourceFile.img destinationFile.iso

You can now use the ISO to create a bootable disk:
