10.3: Create bootable ISO Image CDs using Disk Utility

This is simple - but I haven't seen it described quite this way before. I made a couple of coasters before trying this particular approach. Now that Disk Copy is merged into Disk Utility, this seems to work reliably if you have an existing ISO image:

  1. Insert a blank CD into a supported burner
  2. When the Finder dialog appears, select "Open other application" for the desired action
  3. Navigate as you prefer and then select "Disk Utility" as the desired application to open
  4. After Disk Utility opens, drag the ISO image file to the lower portion (below the horizontal divider) of the left-hand pane where disks and volumes are displayed in the Disk Utility dialog
  5. Select the ISO image file,
  6. Click the "Burn" icon at the top-left of the Disk Utility dialog.
I made a set of bootable Linux install CDs for PC systems in this way. I would expect this method to also create bootable DVDs but have not yet tried it.

BTW, you might intuitively think that opening Disk Utility and executing steps 4 - 6 and inserting a CD would provide the same results but this seems to not be the case. When I tried it that way I invariably received an error message that the media was not writable.
