Problem conclusion

• The problem has been fixed so that the restore operation
  continues if EFI system partition files cannot be restored.
  
  After the system state restore operation finishes, do these
  additional steps to restore the EFI system partition files:
  
  
  1. Mount the EFI partition with this command:
  
    MOUNTVOL x: /S
  
    where x: is an unused drive letter.
  
  2. Restore the EFI files the drive letter specified in step 1
  above:
  
    dsmc restore "{hostname\SystemState\NULL\System
  State\SystemState}\EFI\Microsoft\*" x:\EFI\ -subdir=yes
  -replace=no
  
    where hostname is the name of the system being restored.
  
  3. Unmount the EFI partition:
  
    MOUNTVOL x: /D
  
  4. Continue the system restore as usual.
