windows 10 iso file not working

Installing Windows 10 is a much simpler task than one would expect. You have all the resources provided by Microsoft and all you need to do is get a bootable media (USB or DVD) and deal with the tweaks later on.

Everything in the middle is as intuitive as you can hope for. However, some users who prefer DVD over USB have had a lot of a hard time with that alternate way. Windows 10 ISO file just wouldn’t work.

That’s why we provided you with some more-than-needed steps to resolve this problem. If Windows 10 ISO file won’t work, the steps below should help you address this.


What do I do if ISO files don’t work on my PC?

1. Extract the ISO file using WinZip

If for some reason your PC persists in not accepting ISO files, then maybe extracting it will yield better results.

To that extent, you should use WinZip, since it is the world’s best commercial-grade file archiver and extractor, and it supports all major file formats, including ISO files.

That being said, simply install WinZip on your PC, right-click the ISO file and select Extract here. Once the content is extracted, you can easily gain access to whatever was on the ISO file.

2. Redownload Media Creation tool and try again

  4. Select the Language and Architecture. Click Next.windows 10 iso file not working
  5. Select the ISO file option and click Next.windows 10 iso file not working
  6. Wait for the tool to download the Windows 10 ISO file. It can take some time, depending on your bandwidth speed.
  7. After that, use any third-party tool to burn the ISO file to DVD. Here’s the list of the best ones around.
  8. Stick with the x8 speed to avoid any issues.

Let’s get to the point right away. There are 3 things you need to check. Firstly, make sure that you’ve finalized the downloading procedure. Second thing, confirm that your DVD-ROM is fully functional.

And last but not least, double-check the system DVD you’re using to burn the installation ISO file.

After you’re over that but the ISO file still won’t work, we suggest re-downloading the Media Creation tool from the official Microsoft’s site and moving doing everything from a scratch.

The pirated versions of the system are not what are we referring to and dealing with those is not our current concern.


3. Create the USB bootable drive instead

  1. Plug in the USB stick in the fastest port. It needs to be at least 6 GB (8 GB options are more common).
  2. Open the Media Creation Tool and, instead of selecting ISO, choose the USB flash drive option.windows 10 iso file not working
  3. Wait until the bootable USB is ready.

If you’re not able to create a bootable DVD with the aforementioned ISO file, we suggest going for the USB option. It’s a preferred option for various reasons.

Of course, if you don’t have any urges to go for the DVD instead of the flash stick drive. The creation procedure is similar, but you don’t have to burn it as the Media Creation Tool creates a bootable USB drive automatically.

With that, we can conclude this article. In case you have anything to add or take, make sure to point it out in the comments section below.
