I installed Windows 7 and Windows 8 in EFI mode on a hard disk some days ago. Today, the bootloader got missing/corrupted.

I currently have the Windows 8 installer on a flash drive and tried using the Automatic Repair option to repair the bootloader but it didn't do anything. The Startup Repair option is also missing in the Windows 8 installer.

How I can repair/recreate the EFI bootloader from the Command Prompt?

BCDEDIT returns the following message:

The requested system device cannot be found.
