you typed There IS an "EFI/CLOVER/drivers64UEFI" which tells me you are using a older version of clover, you might want to update that for your system, I am running 5102, you can so this if you have the Clover preference pane in your settings app.
to offer any help, we need more data, what drivers are you using and what kexts do you have. also the config.plist you are using.
Drivers are found in EFI/CLOVER/drivers/UEFI
kexts are found in EFI/CLOVER/kexts/Other
BIOS settings play a big part in this as well.
the more info you provide...
