https://en.wikipedia.org/wiki/GNU_GRUB#Startup_on_systems_using_BIOS_firmware

stage 2: core.img loads /boot/grub/i386-pc/normal.mod from the
partition configured by grub-install. If the partition index has
changed, GRUB will be unable to find the normal.mod, and
presents the user with the GRUB Rescue prompt.

So the answer to your question is, it's been configured at
install time, not discovered at runtime.
