I never switched to a proper efibootmgr setup on mine, I just have loader.efi as bootx64.efi and that's it. >> If there's a way to get into the EFI shell on Lenovo's laptops from the >> BIOS during the boot I've not found it yet.

You can just download the EFI Shell from the internet, it's a normal .efi executable you can "boot". Put it as efi/boot/bootx64.efi onto a USB flash drive and enjoy.
