A version-2.0 EFI is unlikely to work well with an EFI shell version 2; you're likely to need a version-1 EFI shell. This could be the source of your problem, but I can't be sure of that. The Arch Linux wiki has some handy download links for several EFI shell variants:
https://wiki.archlinux.org/index.php/Unified_Extensible_Firmware_Interface#Obtaining_UEFI_Shell
Depending on what boot manager you're using, the ideal location and filename for an EFI shell binary varies. You may also need to explicitly create an entry for an EFI shell much like you'd need for an OS. If Clover remains like its rEFIt ancestor, it will look in EFI/tools on the ESP for an EFI shell binary. My own rEFInd (another rEFIt fork) also looks there. With rEFInd, it should be called shellx64.efi or shell.efi (on x86-64/AMD64/x64 systems). I don't recall offhand if rEFIt used both of those names or just shell.efi.

Yes, an older EFI shell worked. Using that shell how might I be able to add boot entries to my EFI, as I don't have that option in Setup.

Unfortunately, older shells lack thebcfgcommand, so you can't manipulate the boot order with them -- at least, not by themselves. (I've always meant to figure out ifbcfgcould be built as a standalone application, but I've never gotten around to it.)

Yes, that is also true, there is no bcfg command in the shell I am using. The Windows Boot Manager somehow makes it's way into my Multi-Boot list so I know that it's possible to manipulate that list in some way. I don't want to have be dependent on Microsoft's boot program though, as loading EFI programs like your rEFInd require the EFI/Microsoft/Boot folder to exist, and their files.

rEFInd does not rely onEFI/Microsoft/Boot/bootmgfw.efi-- at least, not on a working system. (Some EFIs are very buggy and require using that filename to boot anything, but they're pretty rare.) You can useefibootmgrin Linux to manipulate the EFI boot order list. In Windows,bcdeditcan do the job, as can the third-party EasyUEFI
