Burning ISO image on Windows 10

When I try to burn or mount an ISO image file on Windows 10 or Windows 8.1 an error occurs:

The disc image file is corrupted.


The selected disc image file isn't valid.

I can mount the image file on Mac OS X 10.2. How do I burn this image on Windows 10? I don't have a CD writer attached to a Macintosh computer.

The ISO file is from macos-922-uni and I am trying to install Mac OS 9.2.2 so that I can run Classis apps.

Windows can not read Mac CDs by design, true.
You can however burn all kinds of Mac HFS CD/DVD images with the help of IMGBurn from Windows, if need should be.

For Classic in OSX you might best use one of the pre-built OS9 folders available.

I tried burning the ISO file on a Power Mac G5 running Mac OS X 10.5.8 but that failed. I also tried expanding the Quicksilver_0.sit and selecting it with the Classic system preferences. It attempted to startup but an error stopped that from working.

The system software on the startup disk only functions on the original media, not if copied to another drive.

How can I get my old software to run with Classic? I gave up on Mac OS X because of this problem.

As 24bit mentions. Use ImgBurn to either Rip to .iso or Burn from .iso files on Windows OS's.

Most Mac HFS or HFS+ iso images will be Toast ".toast" or Disk Utility ".cdr", these you can also rename to ".iso" and ImgBurn will be able to use those as well (mostly - there may be some exceptions).

Classic requires 10.4.11 or earlier, So Leopard would be out for running classic software (where you would need to go to emulation to run classic software). But Disk Utility or Toast should be OK for ripping CD/DVD media and Toast should be fine for mounting .iso images as virtual CD/DVD's for accessing. Disk images can also be added to an emulator's GUI and have them mount onto an emulated desktop for access.
