Install.nsh not working - boot.efi does nothing

Need some help. I am trying to get Catalina 10.15 up on my Windows 10 PC(i7) via VirtualBox. The UEFI shell boots up and then i get:

“\system\library\coreservices\boot.efi is not recognized as an internal or external command, operable program, or script file.”

If i enter install.nsh it goes and executes “boot.efi” and nothing happens.

What am i missing here? Anything helps. Been stuck for a bit now
