It depends which GRUB boots.

If it's the GRUB on the hard disk that was /dev/sda during the 
installation, it will show the same systems as before the installation, 
i.e. it won't show the new system until you run update-grub to update 
its menu.

If it's the GRUB on the device that was sdc during the installation, it 
will show all present systems that os-prober can detect.

Indeed.

You did not mention previously that /dev/sdc was a USB device.

The boot order in the BIOS has no effect on the device discovery and 
naming in the Linux system. Also, most of the times USB devices lose the 
discovery race against ATA devices due to extra delay. So hda will 
probably always be the hard disk regardless of the boot device.
