Reasons For The Error “Unable To Recover Your PC. The System Drive Is Too Small

Before we go on to discussing the solutions to resolve the error, we must be clear about the probable reasons that are causing the error.

Let’s take a look at the root causes that might probably be causing this error to display.

● The disk where you are trying to restore the system image may not have adequate space. It might also be of inadequate size to allow the function.

Ways to Fix the Error “Unable to recover your PC. The system drive is too small.”

We are committed to delivering the most appropriate data recovery solutions for a variety of issues faced by users all across the country. Here we have listed the simplest and quickest solutions to fix the error, Unable to recover your PC. The system drive is too small.”

Solution 1: Checking the target disk size and capacity

When you see this error, you must check the size of the target disk and ensure that its size is greater than or equal to the size of the original or source disk.

This is regardless of the size of the system image that you had created or the total space occupied by the data stored on the disk. To make it more clear, if your original disk size was 250 GB but contained only 100 GB of data, your target disk must also have at least 250 GB of storage capacity.

If your target disk has adequate size, but you still see the error message, follow the next solution.

Solution 2: Editing The Minimum Required Size

The minimum required size of the target disk is automatically saved while you are creating the system image. It is stamped in the file named, “$PBR_ResetConfig.xml”.

When you open this file, you’ll see something like this.


The <MinSize> that reads the value 1000000, basically means 1000000 MB, which is also the minimum required size of the target disk.

Reconfigure this value if your target disk size is inadequate. To edit the value of this attribute, follow these navigation steps:

System image file >> sources >> Then open the $PBR_ResetConfig.xml file on a notepad >> Find the <MinSize> attribute and then edit the value.

If you still see the error message on your system, move on to the next solution.

Solution 3: Getting An Error While Restoring To An External Disk? — Try This Solution!

The original disk and the target disk, if different, creates a conflict and will lead to the display of the error. To override this error, you need to remove the original disk if you choose to restore it to an external disk.

The external target disk then gets the same ID as of the source disk and allows the system recovery process. If both the disks coexist on the system during restoration, the ID conflict disrupts the restoration.

If this step doesn’t resolve the issue, try the next method.

Solution 4: Formatting The Drive and Deleting Existing Partitions

A disk that is already partitioned might lead to an error while restoring the system image. Format the target disk and remove all partitions (volumes).

Follow these steps to format the drive and remove all volumes:

Warning: This will delete all data on the target disk!

● Connect the target disk to a system

● Then press the Windows+R button. In the Run window, type in diskmgmt.msc and click OK.

● Select the partitions on the disk and delete them all.

● After all the partitions are deleted, format the disk.

Also note, that your disk will now appear as “Disk 1” in the Disk Management Utility.

If the issue still persists, try the next step.

Solution 5: Recreating The System Image

1. Open the Control Panel on Windows

2. Click on the “Backup and Restore” option
