ISO image (also called optical disc image, based on a bootable CD/DVD or Blue-ray, from the ISO 9660 file system used with CD-ROM media), is a disk image that contains an exact, sector by sector copy of an optical media, such as CD/DVD or Blue-ray disc. 

It can be created from optical discs by disk imaging software, or from a collection of files by optical disc authoring software, or from a different disk image file by means of conversion. 

3 Common ways to create an ISO image of my hard drive

As mentioned earlier, there are two types when we say "create an ISO image of my hard drive", namely create image for optical disc, create disk image. Then, how to make it? Please check the following situation and choose a proper method: 

Situation 1: You want to create an ISO image for optical disc

If you are in this situation, there are two ways you can try, including using DISM (Deployment Image Servicing and Management) and Media Creation Tool.

The first one is command line utility to capture Windows image under recovery environment or create ISO image (.wim) of hard drive in Windows 10/11 for deployment. It requires a Windows 10 recovery media or installation disk. While for the second one,  it's a way recommended by Microsoft, and you can use it to install or upgrade Windows.

Situation 2: You want to create disk image or clone hard drive to ISO

For this situation, disk imaging software will be a better choice, and you can customize the backup task, for example, create disk image weekly, compress disk image if it's really big, etc. Also, it requires a system restore in case of system or boot failure.

 In addition, cloning is worth trying, it's a simplified version of backup and restore and you can directly use it to boot a failing computer by replacing hard drive and setting boot priority for it.

Situation 3: You want to create a bootable USB

This is mostly done as a precautionary measure, so you can boot your computer when it fails and perform disk or system recovery. You have 3 different ways, namely using installation disc, Recovery Drive in Windows 10 or third-party media creator tool, such as AOMEI Backupper Standard. Note recovery drive only works on the same computer where you created it. 

How to create an ISO image for optical disc

In this part, you will learn 2 ways to create an ISO image for optical disc. Method 1 is recommended. By comparison, it's much easier than capturing image with DISM. And the DISM tool is more suitable for professionals or IT technicians.

Method 1: Create Windows 10 ISO image using Media Creation Tool

1. Go to Windows 10 download page, and click Download tool now to download the Media Creation Tool. 

2. After downloading, open this tool and select Create installation media (USB flash drive, DVD, or ISO) for another PC. Click Next.

Create Installation Media

3. In the current window, select the language, architecture, and edition of Windows you want. Click Next.

4. Select ISO file > Next, and the tool will create your ISO file for you. To use the ISO file as a backup for your PC or on another PC, you can choose to burn it onto a CD/DVD or USB drive.

Select Media

Method 2: Create an ISO image of my hard drive with DISM 

Here you will use the second method to make HDD/SSD to ISO image in Windows 10/11 with DISM. Before starting, you need to determine which partitions to capture. Note you do not have to capture Microsoft Reserved partition and extended partition because they are managed automatically.

Then, you need to assign a drive letter to this partition if it doesn't have one. Boot your computer from the recovery media or installation media.

At the Windows PE command prompt, type “diskpart” to open diskpart tool. And type the following commands in order and hit Enter after each command. 

  • list disk
  • select disk 0 (0 is the disk number including partition you want to capture)
  • list partition
  • select partition=2 (the partition you want to capture is partition 2)
  • assign letter=S (assign the drive letter for partition to S)
  • exit

Assign Letter

After determining the partition you want to capture and assigning drive letter for it, you can start to capture image officially with the following command. You need to boot into WinPE environment.

Dism /Capture-Image /ImageFile:s:\my-system-partition.wim /CaptureDir:S:\ /Name:"My system partition"
