Are you plagued by the error “Unable to recover your PC. The system drive is too small” when you want to recover Windows. This article provides you 5 effective ways to resolve this error. Read on to find out.
Unable to recover - System drive too small
“After installing Windows 10 last week, I created a system image using the built-in backup software. The system OS SSD is 120GB. Over the weekend I restored my system back to Windows 7 using a prior image so I could transfer a software license for a program I needed. Same SSD with Win7 and Win10 - now when trying to restore my Windows 10 image, I receive the error that my system drive is too small. This doesn't really make any sense to me - I've never had this issue with Windows 7. I don't mind doing a full Win10 install again if I have to, but I'd rather not as I had it all setup how I want. Any suggestions would be greatly appreciated. Thanks...”.

When your computer is in good working order, you can use a system image to create a complete copy of all the data on your computer, including files, system settings, and Windows. If your computer suddenly crashes or otherwise unexpectedly happens, you can use this Windows system image to restore your computer to a working condition.
However, there may be some issues with the recovery process. The unfriendly error message "Unable to recover your PC. The system drive is too small" may appear. So how to fix this frustrating error? In this article, we will show you 4 solutions.
Before we start the process of fixing the problem, we can first find out the reason behind the error and find the corresponding method according to the reason. Starting with the cause, let's see what is the culprit causing the “Unable to recover your PC. The system drive is too small” error.
✪ Insufficient disk space: The disk to which you want to restore the system image is out of space. ✪ System image issue: There was a problem with the system before the system image was created. ✪ Hard disk problems: Existing partitions on the hard disk can cause errors to occur. Or your original disk conflicts with the destination disk.
After figuring out the cause, let's fix this error with effective solutions.
When the “Unable to recover your PC. The system drive is too small” error occurs, the easiest way is to check the capacity of the hard drive. You need to ensure that the capacity of the disk is greater than or equal to the source disk. To do this, follow the steps below:
If the size of the target drive is equal to or larger than the source disk but you still get the "Unable to recover your PC" error, try the next method. If the target disk is smaller than the source disk, you can choose to clean up the target disk space or use another restore your PC to a smaller disk - AOMEI Backupper to help you.
When a system image is created, the minimum size required for the target drive is automatically marked in the file - $PBR_ResetConfig.xml. The value you see in this file is the minimum size (in megabytes) required for the target drive. It indicates that you may encounter the error “Unable to recover your PC. The system drive is too small” even if the actual size of your target drive is greater than or equal to the source disk, but less than the value.
If this is the problem, you can try editing the value of the property. To do this, open system image file -> sources -> open the $PBR_ResetConfig.xml file on a notepad, look for attribute and change the value to make sure it is smaller than the target drive.
Sometimes you will restore a system image to a used disk with partitions. If you are encountering the error “Unable to recover your PC. The system drive is too small” in this situation, you can try to delete the existing partition and format the drive to resolve this error.
❀ Note: Doing so will delete all data stored on the used disk, you can back up important files on it first.
❀ Tip: If the disk you are using is an external disk, its name will probably appear as Disk 1 or similar under the Disk Management utility.
Another possibility is that there was a problem with the system before the system image was created. You can use the SFC command to repair your system files and then recreate a system image.
❀ Note: Running the DISM (Deployment Image Servicing and Management) tool prior to SFC is only necessary on Windows 10/8.1/8. To run sfc /scannow in Windows 7, you can skip to Step 3.
If none of the above methods solve your problem, don't be discouraged, here is another method that can help you recover your PC. AOMEI Backupper, a powerful backup software that can help you create system images and help you recover your PC easily.
