Changing $prefix is pointless. GRUB BIOS cannot use GRUB EFI modules and vice versa.

So, at this point, GRUB BIOS was installed in the MBR but its modules are missing. Maybe an old deleted installation. GRUB EFI is installed, but is not booting. GRUB BIOS is booting instead. Check the boot options in the firmware settings.

Note that the Windows system on the same disk was installed for BIOS boot and won't boot from GRUB EFI. Maybe did you change the boot settings to be able to boot Windows again ?

I would advise to re-install GRUB BIOS properly. On Debian, this could be done by installing the grub-pc package. I do not know Parrot OS.
