Is this fixable with a UEFI boot USB (Installer) without having to reinstall entire OS X ?

I know I can reformat EFI partition with mkfs_dos or some such, and perhaps copy EFI partition from USB to HDD via Terminal?

Just need the commands to do it...

NOTE: I can access most of the decompressed files read-only from Windows (which is booting fine). I think it was Clover Configurator which destroyed my EFI partition :-(
