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.
As UEFI and GPT are increasingly widespread, older images of MBR disks often need restoring to replacement UEFI / GPT systems.
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.
Boot into Windows PE.
Open a Windows command window. To open a command window click the icon
on the taskbar.Type:
diskpart
Type:
list disk
Select the disk number that you want to restore to. For example:
select disk 0
Clean the selected disk:
clean
By default, "clean" creates an empty MBR disk. Convert it to GPT:
convert gpt
Create the EFI partition:
create partition efi size=200
Format the EFI partition:
format fs=fat32
Create the MSR partition:
create partition msr size=128
Exit Diskpart:
exit
- In Macrium Reflect, click Create Backups tab.
- Click Refresh to read the newly initialized disk.
- Click the Existing Backups tab.
- Select the image file and select the Restore icon, drag and drop the imaged partitions but DO NOT restore the MSR partition from the image file. In this example, only the C partition is restored to the target disk.
When the restore is complete, configure the UEFI boot files in the EFI system partition.
