Need a quick and easy way to backup and restore Windows without relying on backup tools or the cloud for your personal data?

Several third-party Windows backup and restore tools are available, but they can be complicated and time-consuming to use. So, why not learn how to make an ISO image of your Windows PC instead?

Why Choose a Windows 10 Image Backup?

We all know that backing up our data is important, especially when upgrading to a new version of Windows. But rather than fiddle around with partitions for specific data, or syncing to the cloud, why not simply back up your entire Windows installation?

You can add personal folders to an image backup, but omit apps and games. Alternatively, you could opt to create an image of your entire system drive. Naturally, you would need a suitable volume of storage for such a backup.

Thanks to the ISO image format, it is possible to back up your entire PC. This essentially creates an exact copy of your entire drive or selected directories. You’ll be able to restore the image backup should disaster strike.

Although cloud backups are easy, there’s no reason not to prepare an ISO disk image for disaster recovery scenarios. You might make an image of the system in its current state.

This might be an external hard disk drive or some other large volume. You can also write to DVDs (you’ll need more than one) or Blu-ray.

Do you have a home server, or some large storage on your network, perhaps in the shape of a purchased NAS? If so, you can use the On a network location option. If you want to use a USB flash device, connect this to your computer in advance and select it as the destination.

Also ensure that the System drive (by default the C: drive) is selected.

The confirmation screen will detail how much space will be taken up by the backup. Check this to ensure the figure matches the remaining space on the target device. Proceed with the backup and wait while it completes. The duration will depend on the size of the backup and the speed of the drive.

Restoring Your Windows 8.1 Disk Image

If a Windows 10 upgrade doesn’t work out for you (perhaps you’ll experience a reboot loop), having an ISO image to fall back on is a massive advantage. You can restore the Windows 8.1 disk image in Window’s Advanced options screen, which you will find by pressing F8 repeatedly when your PC boots up (or holding SHIFT as you click Restart).

In Advanced Startup Options, select Repair your Computer > System Image Recovery and follow the instructions, ensuring that Windows can find the ISO file.

Note that even if you have the Windows 8.1 installation media you can still restore the disk image. At the Install now screen, use the Repair your computer link and then Repair.

From here you’ll be redirected to the Advanced Startup menu, so select Troubleshoot > Advanced options > System Image Recovery, following instructions to restore your Windows ISO system image.

Back Up Your Windows PC With an ISO Image

As you can see, creating an ISO image backup of your entire Windows system is perfect for backing up in advance of a major system upgrade.
