I have a bootable dmg image and I need to burn it to a double layer DVD (the only one I have right now).

I don't have Mac just my Ubuntu PC and I heard it's possible but searching google didn't answer my question. So would you please tell me how can I do that without damaging the file or the only DVD I have right now?

The easiest way to do this seems to be converting the dmg to an iso file.

Managing Disk Images on the Ubuntu wiki explains this very well for different formats including dmg.

I know this is 4 years later, but if I was pointed here others will be too.

1. Download *.dmg.
2. sudo apt-get install dmg2img
3. dmg2img *.dmg *.img
4. brasero (make data file... burn as *.iso)
5. gparted (select USB - unmount - make FAT32)
6. Mount the USB device.
7. sudo add-apt-repository ppa:gezakovacs/ppa
8. sudo apt-get update
9. sudo apt-get install unetbootin
10. sudo unetbootin (select disk image,point to *iso, your usb device should be in the top level of the drop down list, and burn it)
11. It will 'hang' in the middle and then it will install complete, so don't rush to judge and cancel while its in the middle of processing ;)

You could try all2iso. You open a terminal and write

dmg2iso filename.dmg filename.iso

And that's all. It will be bootable, I have not tried with a .dmg file, but I've tried with other filetypes and all2iso. 1
