The Unified Extensible Firmware Interface (UEFI) is an interface between a computer's firmware and operating system. It is designed as a replacement for Basic Input/Output System (BIOS). UEFI supports hard disks with either master boot record (MBR) or the newer GUID Partition Table (GPT) system. GPT is a newer standard that supports disks larger than 2TiB and allows for more than four primary partitions per disk.

This article covers restoring a disk image of a UEFI/GPT system and enable the restored image to boot using legacy MBR booting. 


Caution: We assume there are no other hardware differences between the system being imaged and the system being restored to. For dissimilar hardware, use ReDeploy. 

  1. Boot into Windows PE.

  2. Open a Windows command window. To open a command window click the icon  on the taskbar.

  3. Type:


  4. Type: 

    list disk

  5. Select the disk number that you want to restore to. For example:

    select disk 3
    Please ensure that you use the correct disk number in the above command.
  6. Clean the selected disk:


  7. Ensure that the target disk is MBR formatted

    convert mbr


  8. Create the Microsoft System Reserved partition

    create par pri size=300

  9. Format the MSR partition:

    format fs=NTFS quick

  10. Set the partition 'Active'


  11. Exit Diskpart:



  12. In Macrium Reflect, click Backup tab.
  13. Click Refresh to read the newly initialized disk.

  14. Click Restore tab.
  15. Select the image file, drag and drop just the Windows System partition to the free space on the target disk. In this example, only the 'C:' partition is restored to the target disk.

    Note: You can click 'Restored Partition Properties' to resize the restored partition to fill the new disk if you wish.

  16.  Follow the steps in the section Fix boot problems on MBR/BIOS systems in the following KB article:
      Fixing Windows boot problems

    Note: You should select the newly created 300MB partition as the 'Active' partition when running 'Fix Boot Problems'
