BRC - How to create a system EFI disk partition in a BMR

The system EFI partition is used by the GPT disk to map the disk partitions. 

To create the system EFI partition during a BMR recovery, do the following:

1. In the BMR Utility, select the Utils/Tools option. 
   
2. Next, select the DOS Window option.
   
3. In the DOS Window,  select the target disk, which will be the primary boot disk. The user will need to clean the disk, and convert it to GPT.

   Enter the following commands:
   diskpart - Enables the Microsoft Disk Part Utility.
   select disk 0 - Select the target disk. If there are two disks, the user will need to select one as the primary boot drive.
   clean - Wipes the disk clean.
   convert gpt - Converts the drive to a GPT drive.
   
   
   

4.  Next, the user will need to create the EFI partition, and format it as FAT32.

   Enter the following commands:
   create partition efi size=100 - Creates the EFI partition in Megabytes. Create the partition size as needed.
   format fs=fat32 quick - Formats the partition as FAT32.
   
   
   

5. Finally, the user will need to create the remaining primary disk partitions, format it as NTFS and assign a Drive letter. The user must create at least one primary drive, otherwise the BMR will overwrite the System EFI partition and the device will not be bootable. The user can create these using the DOS Window, or by using the Disk Partitioner tool.

   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://
   
   
   

6. Continue with the BMR recovery process. Make sure that the Use Existing Partition Table box is checked before beginning the BMR recovery.
