I don't remember seeing it in this thread. Message-ID ?

Fine. Sector 2048 is the beginning of the BIOS boot partition, which is 
the intended location for GRUB's core image on a GPT disk.

Why did you use GPT ? It can be required for EFI boot with some (broken) 
UEFI firmwares, but I do not see any advantage for BIOS boot.

Also, why does sdc2 have the "EFI system partition" type ? I assume it 
is not really a ESP containing a FAT filesystem for EFI boot but an ext* 
partition (according to the embedded module list in GRUB's core image). 
So yo should change it to not confuse the UEFI firmware.

As required by the GPT specification, the boot flag of the GPT partition 
of the protective MBR is not set. But some BIOS/UEFI firmwares require 
it for BIOS/legacy boot. So you may try to set it with parted or fdisk.

# parted /dev/sdc disk_set pmbr_boot on

or

# fdisk -t dos /dev/sdc
