CONVERT AND BURN MAC .DMG OR .IMG FILES TO .ISO WINDOWS PC-COMPATIBLE DISK IMAGES:

Question: I have a PC with a DVD burner, but I don't have a burner on my Mac (or the one on my PC is way faster, so I'd like to use it instead). Is there any way I could use the Disk Image file (.dmg or .img) created by iDVD to burn the DVD on my Windows PC instead?

Answer: (found here) You will have to convert the disk image file created by iDVD to the .iso image format (making it compatible with almost any PC disk burning application, such as Nero or Roxio). To do this, follow these steps:

Open Disk Utility (located in Applications>Utilities folder).

Drag your disk image into the left-hand pane (where all your drives are listed) of Disk Utility.

Click on the file you just dragged into Disk Utility (should appear in the left-hand column).

Click on the 'Images' menu, then choose 'Convert...'

When the 'Convert Image' dialog pops up, select 'DVD/CD Master' from the 'Image Format' pop-up menu.

Name your file, with '.cdr' at the end of the filename, then click 'Save.'

Disk Utility will convert the file to an ISO image. After this finishes, replace the 'cdr' at the end of the filename (in the Finder) to 'iso'.

Now, the disk should be burnable on a Windows PC (simply copy the file to your PC by either copying it across a network or using some other means of transferring the data).

Note: This works burn any Mac .dmg or .img files on a PC.
Note 2: Another way to do this is to use the program ISOlator
Note 3: For those of you who may be command-line junkies, there's an alternative method (and another).

Note - I found that between the built-in OS X Disk Utility program and this freeware app called Burn 1.6u:

I can pretty much handle all the basics, saving the need to purchase Toast or some other commercial app. At least so far.

I also found a tidbit that says if you find a . TOAST disk image, you can simply rename it to .ISO and burn it with the Apple OS X Disk Utility as well.

Nice...

Not the most intuitive, but still, it's all free.

Wish Windows had this stuff built in.

OK, so I see you want to burn a disc from the faster optical drive of your PC. I Think this is not a good idea unless you in a huge rush. Your spending more time finding a way to burn then burning itself. The faster you burn a disc the more likly it is to give an error. I never go aove 8x on a dvd or 16x on a cd (The measurement "X" is different from disc type to disc type). When drive say "54x cd speed compatible" that means they managed to burn ONE successful cd but do not mention the success rate.

On Mac OS X 10.4 using Disk Utility Version 10.5.6 (198.12), THIS DOES NOT WORK!

I went back to a dozen DVDs I'd burned and to what should have been ISO file images. They all contained the HFS+ file system. Totally bloody useless for reading or burning under Windows or Linux. If you think I sound a little irate, you'd be right. Yes, it would have been better if I'd checked the first converted image file. So, my fault, there, for trusting these instructions.

Learn from my experience. If you follow these instructions, make damned sure the resulting image is Joliet format, not HFS+.
