Problem:     Installed Windows 7 and Windows 8 in EFI mode on a hard disk some days past. Today, the boot loader is absent or corrupted. At present have the Windows 8 installer on a flash drive and tried using the Automatic Repair option to repair the boot loader but it didn't do anything. The Startup Repair option is also absent in the Windows 8 installer. How I can repair or recreate the EFI boot loader from the Command Prompt?

Go into the Advanced option
