The ISO file itself is generally useless until it can be written (burned) to a disc. The disc burning software you already have on your computer might have a "write image" or "burn image" option designed specifically for writing ISO and other types of image files to optical discs. However, if you have trouble getting your burning software to write ISO files or you would prefer a detailed guide using a freely available ISO burning program, this step-by-step, visual guide will help. The instructions we've put together here walk you through the entire process of installing and using the Free ISO Burner software to write an ISO file to a disc.

Insert a blank disc in your optical drive for the burning of the ISO file. Free ISO Burner supports all standard types of CD, DVD, and BD discs. However, you should use an appropriate size of empty disc per your ISO image. For example, an ISO file that's larger than a CD but smaller than a BD should be burned to a DVD, and so on. You can reference this Table of Optical Media Storage Capacities if you think that information might be helpful in your decision. 06 of 10 Locate the ISO File You Want to Burn ISO Image File Selection Dialog Box. Back on the Free ISO Burner program window, select Open to the right of the long text box, under the heading ISO File. The Open window you see above will appear.

Select Burn to start the process of burning the ISO file to the disc in the drive. You'll know that burning is taking place because the status will change from IDLE to WRITING, you'll see a percentage indicator increasing, and you'll see the progress bar moving. I skipped discussing the items under Options because they're not necessary to adjust unless you're troubleshooting a problem with your optical drive or Free ISO Burner. 10 of 10 Wait for the ISO Image to Finish Burning Free ISO Burner Image Write Done. Free ISO Burner is done burning the ISO file when the status changes back to IDLE and you see Write ISO image done in the Progress box. Once this happens, the disc will automatically eject from the drive. The time it takes to write the ISO image will depend mostly on the size of the ISO file and the speed of your optical drive, but the speed of your overall computer has an impact, too. Need Help?
