Assign drive letter to the System Reserved Partition on MBR disks and set it as Active.
Delete previous system restore points and turn off Windows system protection for all hard drives. Press Windows Key + S and type System and choose it. Click on System protection on the left of the popping up window. Locate Windows 10 System Image and click Configure. Select Disable system protection and click Delete beneath.
