After waiting on the download page in the last step, the actual Free ISO Burner program will begin to download. It's small so it may finish downloading before you even realize it's started.

If prompted, choose to Save or Save As or Download the program—don't just run or open it from here. While that would probably be fine, sometimes it just complicates things.

The screenshot above shows the prompt asking where to save Free ISO Burner in Windows 10, using the Google Chrome browser. If you download this file using another browser or a different operating system, your download progress manager or indicator might look different.

After downloading Free ISO Burner, locate the file and run it. Free ISO Burner is a portable application, meaning it doesn't need to be installed—just double-click on it and the software runs.

If you're having trouble locating the FreeISOBurner.exe file you just downloaded, check your Desktop and Download folders, the two most common locations for storing downloaded files. If you were asked to choose a specific folder during Step 3, look in that folder.

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.

Confirm the Selected Drive

The next thing to look at is the Drive option... assuming you have one.

If you have more than one optical disc drive with burning capabilities, you may have more than one option listed here. Check to see that the drive that's selected is the one you actually have the disc in.

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.

Wait for the ISO Image to Finish Burning

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.
