A disk image, in computing, is one or more computer files containing all the contents, file system, boot file and partition table structure information of a disk volume or an entire data storage device, such as, hard disk, floppy disk, optical disk, or USB flash drive.
And it is usually made by a sector-by-sector copy of the source device. Typically, the disk image file extension can be open standrd, such as, .iso for optical disc images or other file extensions for a particular software, dmg(apple disk image), .vhd, .img, .toast, .adi etc. Besides, the .WIM disk image is a file-based format.

To prevent your hard disk drive from the data loss due to unpredictable error, it’s highly recommended to create disk image for Windows 11, 10, 8, 7 hard drive. There are two ways to create disk image:
Windows Backup and Restore. Backup and Restore is a built-in free backup software and has the ability to create a system image backup. To create disk backup, you need to select other non-system partition(s) manually.
Best free create disk image software - AOMEI Backupper Standard. Similarly, it's a free backup software, but you can directly create a disk backup with it. And you can schedule backup disk in daily, weekly, monthly and backup only changed files by default.
From above, it's not difficult to see the second way is much easier. And you enjoy more advanced features in it. Here I'll introduce it first.
Now we are going to create disk image for an SD card, USB flash drive, external hard drive, CD/DVD, local disk, etc. And you will use the best free disk image software - AOMEI Backupper Standard, it's is popular all over the world due to its flexible backup solutions and professional backup strategy. Besides, you could create a system image if it's a system disk and the target disk does not have enough space.
Of course, if you don't want to compress disk or system to an image file, try clone feature. You can choose to clone entire hard disk or system to another HDD/SSD without reinstalling everything. Note the free version does not support cloning OS only. If needed, please upgrade to the professional version.
First of all, please download AOMEI Backupper Standard to have a try.
(Note: The free version only supportsWindows XP, Vista, 7, 8, 8.1, 10, 11. For server users, try AOMEI Backupper Server. )
The detailed steps to create disk image in Windows 10 are listed below:
1. Perform AOMEI Backupper Standard, choose Backup -> Disk Backup on the main window.
2. Tap + Add Disk, select the Windows 10 disk that you would like to backup, click Add. You could rename the Task Name to distinguish from other backups if required.
3. Click folder icon or triangle icon to select a destination location, such as an external hard drive, or network drive to save the Windows 10 disk image file.
4. Press the Start Backup button to create disk image safely.
Other helpful features you may want to use:
Click Options to modify the disk image, like split, compress, comment, set backup mode, enable email notification to get noticed after the backup finished.

Click Backup Scheme to choose different backup methods (Full/Incremental/Differential backup). The latter two methods can improve efficiency and save disk space when performing scheduled backups, but incremental backup method is more demanding for restoration.
Thus, it's suggested to upgrade to the professional version and use the differential backup method. After upgrading, you can also enable automatic backup cleanup feature to help you clean up redundant backups regularly.
After the disk backup finished, you will get an image file, suffix with .adi, on your destination location. If you want to restore the data from the image file someday, you could perform selective files restore, or restore the entire hard drive.
Backup and Restore comes along with your computer, thus you don't need to download and install it first. You just need to open it and create hard disk image with the following steps:

Both Windows Backup and Restore and AOMEI Backupper Standard can help you create disk image in Windows 11/10/8/7/XP/Vista, but there are some differences. The previous one does not allows you to create entire disk directly. And you cannot backup external hard drive, USB drive, SD card etc that are not connected to the motherboard.
To backup disk flexibly and make this automatically, it's suggested to use AOMEI Backupper Standard. It uses intelligent sector backup, automatic splitting, normal compression, etc default, which is helpful for saving disk space. And if you enable schedule backup, it will backup only changed files with daily incremental backup. All of them can help you minimize the size of backup image.
Besides, its advanced edition still supports enable encryption for backup, diferential backup, automatic backup cleanup, etc. Among them, the last one can prevent backup disk full issue from the very beginning. To protect unlimited PCs or servers, try AOMEI Backupper Technician or TechPlus.
