How to make a bootable disk from an image with Toast

bootable-diskdvd-burning

I read contradictory information, some say it’s possible, some say it’s not and Apple’s Disk Utility is required.

I prefer to use Roxio Toast for its multi-purpose but I don’t want to waste blank disks.

So is it possible and if yes how to make a bootable disk (DVD or CD) from an image (dmg, iso, toast, cdr…)?

I also heard that it must be burnt at the slowest speed.

Toast:

  1. "Do not mount the Disk Image first!"
  2. Launch "Toast.app"
  3. Click "Data" icon (upper left) and choose ISO 9660
  4. Select "Copy" icon (upper left) and choose Image File
  5. Click "Select" and "Choose a Disk Image File" from the dialog (do not drag and drop).
  6. Click "Burn" et voilà.

Most effective Option:

  1. Launch "Terminal.app"
  2. Use the following command(s). Replace "imagefile.dmg/.iso" with your dir and/or prefferd name.

    hdiutil convert imagefile.dmg -format UDTO -o imagefile.iso                
    hdiutil burn Imagename.iso
    

This method uses the exact pre-installed function of "Disk Utility.app" only without the GUI!
