Can’t Mount Image File The Disc Image File Is Corrupted

Windows 10 has the ability to mount ISO files inherently without the need for 3^rd party applications. This feature was not available in Windows 7 and has been extremely useful after its introduction. By simply double-clicking on an ISO image file, a virtual drive gets created, which can be accessed and even the files can be copied to the PC.

If you are unable to mount image files on Windows 10 and the disc image file is corrupted error pops up while trying it, then it may not only be the image file’s issue. In this article, I have discussed what to do when the disc image file is corrupted in Windows 10.

What Triggers The Error ‘Disc Image File Is Corrupted’ In Windows 10?

When you are unable to mount an image file and the error message shows that the ISO file is corrupted, then it may not be always as the error shows. The basic assumption from the error is that the ISO file is corrupted, and you need to get the uncorrupted copy to use it. However, the following causes can also trigger this issue:

1. 3^rd party applications: If are using 3^rd party applications to mount ISO files, then the application can be faulty or corrupted.
2. Corrupted System files: If your Windows 10 is unable to mount an image file, but the file can be mounted by using a 3^rd party application or on another PC, the system files can be corrupted.

How To Fix The Disc Image File Is Corrupted Error?

Now that you know the different causes of this error, it is time to troubleshoot it. Follow the troubleshooting procedure provided below to effectively solve this issue.

Check If The Image File Mounts On Other PCs

The first thing you need to do is check whether the image file is actually corrupted or not. To check that, simply copy that ISO file to another PC running Windows 10 and try mounting it. If the other Windows 10 mounts the image file easily, then the issue is with your PC and not with the image file.

However, if the image file does not mount in the other Windows 10 PC also, then there is a possibility that the ISO file is corrupted. Based on these observations, proceed with the following troubleshooting methods.

Solution 1: Run SFC And DISM Scans

If you find that the ISO file is mounting on the other PC, then the issue likely stems from corrupted system files. There is a utility in Windows 10 that can check for corruption in the system files and fix it. The name of this utility is System File Checker, which can be done by using the sfc /scannow command line. To run the System File Checker, follow the steps given below:

1. Press the Windows + R keys to open the Run utility.
2. Type cmd in the search box and press Ctrl + Shift + Enter to open an elevated panel.
3. Now, type sfc /scannow and press Enter to run the System File Checker.
4. Wait for the SFC scan to finish. It will take some time to finish, so don’t worry and don’t close it prematurely.
5. Restart your PC after the scan finishes.

After the System File Checker finishes running, check if the ISO file is mounting. If no, then try running the DISM scan, which repairs the Windows image. To run the DISM scan, follow the steps given below:

1. Open an elevated Command Prompt again.
2. Type the following commands and press Enter after finishing each one of them:
   a) Dism /Online /Cleanup-Image /CheckHealth
   b) Dism /Online /Cleanup-Image /ScanHealth
   c) Dism /Online /Cleanup-Image /RestoreHealth
3. Wait for the DISM scans to finish running and restart your PC.

Now, check if the ISO files are mounting or not. If system files were preventing the ISO files from mounting, then this solution should fix it.

Solution 2: Repair The 3^rd Party Image Mounting Application

If you were using a 3^rd party app to mount the ISO file, then the application files may have become corrupted. Try repairing the ISO file, and see whether it fixes this issue:

1. Right-click on the start menu and select the Run option. This will open the Run utility.
2. Type appwiz.cpl and press Enter to open the Programs and Features panel.
3. Locate the 3^rd party image mounting app and right-click on it.
4. Select the Repair option.
5. Follow the on-screen instructions to complete the process.

After you have repaired the ISO application, check if the issue persists.

Solution 3: Reinstall The 3^rd Party Mounting Application

If repairing the 3^rd party mounting application didn’t fix this issue, then try reinstalling it. To reinstall the mounting application, follow the steps given below:

1. Type Control Panel in the Windows Start menu and select the top result.
2. Change the View by option to Large icons.
3. Locate the Programs and features option and click on it.
4. Among the applications listed there, locate the image mounting application and right-click on it.
5. Select the Uninstall option from the right-click context menu.
6. Follow the on-screen instructions to complete the process.
7. After the application has been uninstalled, visit its official website and download it.
8. Install the application again and try mounting the ISO file with it.

Solution 4: Use A Different Image Mounting Application

If the image mounting application is still unable to mount the ISO file, then you should try using a different application. You will find many of these mounting software available online. Try any one of them and see if you can mount the ISO file.

Solution 5: Re-Download The ISO File

If none of the above solutions could help you fix this issue, and you were unable to mount the ISO file on other PCs, then the ISO file is corrupted as per the error message. In this situation, you will have to get another copy of the ISO file, which is not corrupted.
