"UEFI OS" is the default entry.  \EFI\BOOT\BOOTx64.EFI is the default 
location for an EFI boot loader.  It may or may not be present.  Windows 
will put its boot loader in that location, in addition to Microsoft's 
custom location so that if UEFI screws up the boot list, it'll still 
boot the default and Windows won't be broken.  As far as I know, you 
could copy shim.efi to that location to achieve the same thing under Fedora.
