Free Up Space On The Hard Drive

Delete unnecessary programs and software installed on your PC’s hard drive to create space for the newer files required during recovery.

Alter The Minimum Required Size

While shifting the Operating System from one disk to another, you may receive this error if the target disk is smaller than the source disk. In this situation, you can change the Minimum Required Size of the target disk, which is automatically allotted to a file, $PBR_ResetConfig.xml, while creating the recovery drive.

  1. Go to the System Image File.
  2. Pick Sources.
  3. Next, launch the $PBR_ResetConfig.xml file on a notepad.

Upgrade The Hard Drive

You can upgrade the hard drive in your PC to one with a larger storage capacity. Make sure to back up all the essential data stored in the drive to external storage, such as a USB, before replacing it with a better version.

Remove The Source Drive

Remove the source disk if you are backing up the data to an external drive connected to your PC. It will prevent conflicts between the two drives, allowing a smooth recovery process.

Format And Delete Hard Disk Volume

Deleting hard disk volume creates space by cleaning unused disk partitions. Consequently, you can prepare the disk for the new operating system.

  1. Type Disk Management in the Windows Search Bar and launch the results, Create And Format Hard Disk Partitions.

Repair Corrupt Files

Running System File Checker (SFC) Scan analyzes the PC for missing or corrupt files and replaces them to solve the ongoing trouble. Meanwhile, the Deployment Image Servicing And Management (DISM) Scan repairs the Windows Image and several other system and driver errors. These scans are useful in resolving problems related to the Windows OS.

  1. Search cmd in the Search Bar.
  2. Command Prompt will pop up in the results. Run It As Administrator.

Recreate System Image

Creating a System Image refers to creating a backup of all your files, data, programs, and settings. It is ideal before updating the system’s operating system, resetting Windows, or upgrading your PC. With System Image, you can restore your PC to a certain point.

On the other hand, a faulty System Image tempers the recovery phase on your PC. It could be possible that the data within the System Image is corrupt or contains temporary bugs or glitches. 

Store the backup on an external storage device or a separate disk to ensure your data is intact if anything goes wrong during installation or update.

  1. Open the Control Panel from the Desktop.
