Just recently, I was experimenting with a dual-boot Windows setup, and somehow managed to wipe my primary Windows installation in the process. "Why," I asked myself, "Why didn't I make a backup before I started this?" Still to this day, I'm going through the painstaking process of installing and configuring all of my favorite programs, and I may not ever get things back exactly the way they were.
If this nightmarish situation strikes fear into your heart, you'll definitely want to consider making a full system image backup of your brand new Windows 10 installation. Unlike the automated restore point feature, a system image is an exact snapshot of your entire Windows installation, including app settings and data. This means that with a full system image backup on standby, you'll always be able to get your computer back to exactly the way it was—no matter what critical failure caused an issue in the first place.
Before you begin, the process of creating a system image backup requires that you have a place to store the image. Preferably, you should have either a secondary hard drive with plenty of storage space attached to your computer directly or over a network, a large enough USB drive or memory card, or a set of blank DVDs and a disc drive that is capable of burning or writing media.
For a fourth option, you can repartition your primary hard drive to create the storage space needed for a system image backup. This option is less than ideal, however, because the system image will be stored on the same physical hard drive as your Windows installation, which means that if the hard drive fails, you would lose both your Windows install and your backup image.
To begin, press the Windows button on your keyboard, then type "File History" and press Enter.
From the window that pops up next, click the "System Image Backup" button in the bottom-left corner.
Next up, look in the left-hand pane again, and select the option labeled "Create a system image."
At this point, the system image utility will pop up. This first window is asking where you'd like to save your system image, and the options are hard disk, DVD, or network location. Select the storage location for your system image, then if you're saving to a hard drive or USB/memory card, use the drop-down menu to select your preferred drive.
After clicking "Next," you'll be asked to select the drives that you'd like to create a image backup of. Your primary Windows drive and boot sector will already be selected, but if there are any other hard drives containing data that you would like to back up, select them here, then click "Next" again.
Up next, you'll get a chance to review your selections. If everything looks like it should, go ahead and click "Start backup." Depending on how many files and drives you selected, the backup process will take anywhere from 10 minutes to an hour or so.
When the backup process is completed, you'll be asked if you'd like to create a system repair disc. This is purely optional, so you can skip this step if you'd like.
With a system image backup now on standby, you can rest a lot easier knowing that if something ever happens to your Windows installation—be it hardware failure or software issues—you'll be able to get everything right back to normal in almost no time.
Should you ever need to restore your system image backup, start by making sure that the drive containing the backup image is connected to your computer. From here, insert a Windows installation disc and boot into setup.
Once in Windows setup, click "Next," then choose the "Repair your computer" option in the lower-left corner. Next, click "Troubleshoot," then "Advanced Options," and select "System Image Recovery." From here, simply select the system image backup you created, then follow the prompts, and your computer will be fully restored to the exact state it was in when you created the backup.
