here is information collected using gdisk:

I expecte a bit more description of the partitions. There are many disks
and Windows and Linux partitions, so if there are multiple systems
installed it would be helpful to know which partitions belong to which
system.
For now, I can see that sda has a "BIOS boot" partition and its #3
partition type is Linux filesystem, so it is likely that GRUB is
installed in its MBR. I can see only one "EFI system" partition as
/dev/sdb3, so I guess this is the one referenced in your GRUB script.
First I would search instances of GRUB EFI in this EFI partition.
