If the system and boot partitions are located on different drives with GPT disks on a Windows 2012R2 server, the user will be unable to reboot the device once the BMR has completed.
Below is an example of a device that has the System and Boot partitions on two different drives:
In order to successfully perform the BMR and reboot the device once it has completed, the user will need to manually partition the disk of the device being restored. To accomplish this, do the following:
3. First, create the System EFI disk partition. This must be done before the remainder of the disk is partitioned. For instructions on how to do this, please refer to the How to Create System EFI Disk Partition article.
4. Once the System EFI disk partition has been created, create the remaining disks. Repeat this step for as many drives as necessary.
Enter the following commands: create partition primary - Makes it so that the rest of the HDD space is the primary drive. If size is not defined, this command uses everything left on the disk. format fs=ntfs quick - Formats the partition as NTFS. assign letter C - Assigns the partition as Drive Letter C://. This letter can be changed to any preferred drive letter. Return to the BMR utility and continue with the BMR recovery process as normal. Make sure that the Use Existing Partition Table box is checked before beginning.
5. Return to the BMR utility and continue with the BMR recovery process as normal. Make sure that the Use Existing Partition Table box is checked before beginning.
6. Once the BMR has been completed, Press Alt + Tab to open the Cmd prompt. Enter the bcdboot command with the following parameters:
bcdboot c:\windows /s y: /f UEFI
7. Reboot the device. If needed, change the boot option to UEFI if needed.
