Burn an ISO File to CD or DVD with InfraRecorder

An ISO file is a complete disc image — a single file that holds the file system and contents of a CD or DVD. Burning it correctly means writing that image back to a blank disc so the disc boots and reads exactly like the original. InfraRecorder 0.53, the final release from 2012, handles this job directly: it records both ISO and BIN/CUE disc images, supports dual-layer DVDs, and can verify the disc after burning. This guide walks through the whole process step by step, including the write-speed and verification choices that make the difference between a reliable disc and a coaster.

If you have not installed the program yet, get version 0.53 from the InfraRecorder download page first. InfraRecorder is free and open source under the GPL v3 licence. It was written for Windows 2000, XP, Vista and 7. It is not officially supported on Windows 10 or 11, although many people run it successfully there — if you are on a newer system, read the notes in InfraRecorder on Windows 11 before you start, and always use the verification step in this guide so you know the finished disc is readable.

What You Need Before You Start

You need three things: a CD or DVD burner connected to the computer, a blank disc that matches the image, and the ISO file itself saved somewhere easy to find, such as your Downloads folder. Size matters here. A standard CD holds about 700 MB, a single-layer DVD holds about 4.7 GB, and a dual-layer DVD holds about 8.5 GB. Check the ISO file size in Windows Explorer before you choose media — an image that is larger than the disc simply will not fit, and InfraRecorder will stop rather than truncate it. Dual-layer burning is supported, so a large image can go on a DVD+R DL or DVD-R DL disc in a drive that supports dual-layer media.

It is also worth checking that the ISO file is complete. If you downloaded it, compare its size with the size published by the source, and use a checksum when the source provides one. A truncated or corrupted image will burn without complaint in some tools and then fail when you try to use the disc. Burning a verified source image, and then verifying the finished disc as described below, closes both ends of that risk.

Step by Step: Burning the ISO Image

1. Insert a blank disc. Put the blank CD or DVD in your burner and wait a few seconds for Windows and the drive to recognise it. If a Windows autoplay prompt appears, close it — you do not need it for this task.
2. Open InfraRecorder. Launch the program from the Start menu or desktop shortcut. The main window shows your drives and a welcome screen with common actions.
3. Choose the burn image action. On the welcome screen, select Write Image. If the welcome screen is not showing, use the menu instead: go to Actions > Burn Image. Both routes open the same file picker.
4. Select your ISO file. Browse to the folder that holds the image, select the .iso file, and click Open. InfraRecorder reads the image and shows the recording dialog with information about the image size and the disc in the drive.
5. Check the target drive. If you have more than one optical drive, confirm that the recorder shown in the dialog is the drive holding your blank disc. Burning to the wrong device is a common and avoidable mistake on multi-drive systems.
6. Set the write speed. Open the speed list and choose a moderate speed rather than the maximum — see the advice in the next section. For most combinations of drive and media, half of the disc’s rated speed is a sensible starting point.
7. Enable verification. Tick the option to verify the disc after writing (sometimes labelled as verifying the recorded data). This adds a few minutes, but it reads the finished disc back and compares it with the image, which is the only way to be sure the burn is good before you need it.
8. Start the burn. Click OK or Burn and wait for the progress bar to complete. Do not run heavy programs, and do not open the drive, while writing is in progress. The drive buffer needs a steady flow of data.
9. Let verification finish. After writing, InfraRecorder ejects or re-reads the disc for verification depending on the drive. When verification passes, the disc is ready. Label it with a soft disc marker, not a ballpoint pen, and store it out of direct sunlight.

Choosing a Write Speed That Works

Maximum speed is tempting because it finishes sooner, but it is the single most common cause of marginal burns. The dye layer in recordable media is more forgiving at moderate speeds, and older drives — the kind most likely to be paired with a 2012 program — track better when they are not pushed to their limit. Version 0.53 specifically fixed a write-speed detection issue and a bug where the maximum write speed was used instead of the selected one when burning DVDs, so the speed you pick in the dialog is the speed you should get. If a burn fails or verification reports errors, reburn the same image on fresh media at a lower speed before you suspect the image file.

Media quality matters as much as speed. Branded discs from a reputable maker fail far less often than unbranded bargain spindles, especially for dual-layer DVDs, where the layer break makes writing more demanding. If you only burn occasionally, buy small packs of good media rather than a large spindle that will sit ageing for years.

If the Burn or Verification Fails

A failed burn usually comes down to one of four causes: poor or damaged media, too high a write speed, a corrupted source image, or another program interrupting the write. Try a fresh disc from a different batch, lower the speed, and close other applications. If verification fails on Windows 10 or 11 in particular, be aware that inconsistent verification and burns that complete yet read back blank have been reported by SourceForge users on those systems — one more reason the verification step is not optional there. Reburning the same image on a Windows 7-era machine, or checking the disc in a second drive, helps separate a media problem from a system problem.

Working in the other direction? The guide to creating an ISO image from a CD or DVD shows how to save an existing disc as an image file in the first place. If your image came as a pair of files rather than a single ISO, see how to burn a BIN/CUE image instead — the process is similar, but the cue sheet plays a role you need to understand.
