Use the Windows 10/11 ISO Image Created from Existing Installation

In general, there are two ways you can make use of the Win10/11 ISO image file.

Case 1. Burn ISO file into CD/DVD/USB

No matter in which way you create the Win10/11 ISO, you can burn it into a CD, DVD, or USB and then rely on the DVD, CD, or USB to install Windows 10/11 or something like that.

You will need a professional ISO burner. The Windows Media Creation Tool itself is also an ISO burner. So, you can continue to use it to burn the created Windows 10/11 ISO to a DVD or USB.  

For the first place, insert a USB or DVD into your machine. The target disc will be overwritten and the data on it will be deleted. So, make sure you have moved out all important files before using it to store the ISO image. A blank disc is recommended here.

Actually, when the media creation task completes, Windows Media Creation Tool will provide you two options, one for opening the location where the created ISO is stored and one for launching the DVD burner. Just click the Open DVD burner option, select the target disc in the new Windows Disc Image Burner window, and click Burn to start the task.

Tip:
  • You can check the integrity of the burned disc by ticking the Verify disc after burning.
  • If you are informed that the disc image file is too large while burning a DVD from an ISO file, you will need to use Dual Layer (DL) DVD Media.

You can also access the Windows Disc Image Burner by right-clicking on the created Windows ISO file in its saved location and select Burn disc image. If you cannot see the option, you should first go to the ISO file Properties, and change the Open with app of the ISO file to Windows Explorer in the General tab. You need to click Apply to save the changes.

change open app

You can also use other applications to burn the created Windows ISO to CD/DVD such as UltraISO. Also, you are able to burn the ISO image into a USB disk with third-party tools like Rufus.

After burning the bootable disc, you need to change computer boot order settings to switch from the current boot disk to the new burned media, restart your computer to boot it from the bootable media, and enter the Windows installation. In the Install Windows screen, personalize your language, time, and keyboard preferences, select Next, and click Install Windows.

Case 2. Mount Windows 10/11 ISO Image

Besides, you can directly make use of the created system ISO. Easily, right-click on the ISO file and choose Mount. Within the mounted DVD drive, double-click the setup.exe to trigger the Windows 10/11 Setup. Then, follow the on-screen guidance to finish upgrading to Windows 10/11.

Actually, you can directly create a bootable CD/DVD/USB with the software above. Doing that, you do not need to further burn the ISO image into a physical disc or USB.

Why Need to Create Windows 10/11 ISO Image from Existing Installation?

Just as mentioned in the above content, the Windows ISO image file can be used to install a system or boot up dead computers. Compared with the bootable USBs, CDs, or DVDs, which has the same function as the ISO files, ISO images have the following advantages.

  • No need for extra devices like CD, DVD, or USB.
  • You can view its contents by mounting it as a virtual drive.
  • You can run the ISO file on a virtual machine.

To install Windows 10/11, you can also make a system backup image and restore it to its original location (reinstallation) or another computer (clean installation) with MiniTool ShadowMaker. Yet, an ISO file is better than a backup image file for:

  • Easier to be deployed on any computer.
  • You can view its contents by mounting it as a virtual drive.
