If you cannot recover EFI partition, you need to create an EFI partition and then install EFI boot loader to make the hard drive bootable.
Step 1. Boot your computer from a Windows installation disc or recovery disk. Press Shift+F10 in the setup to enter command prompt window.
Step 2. Run the commands below to shrink a partition to get unallocated space.
Diskpart List disk Select disk X (X represents the disk number of the disk that needs an EFI partition) List partition Select partition N (N represents the partition number of the partition that needs shrinking) Shrink desired=500 (shrink the partition by 500MB) Step 3. Then you can create EFI partition using unallocated space with the command below:
create partition EFI size=200 format quick fs=fat32 label="System" create partition msr size = 128 Step 4. After those two partitions have been successfully created, use the commands below to install boot loader and other applications needed.
