GRUB does not change very often. So you simply had luck, that the exiting embedded grub-bootloader on the MBR was still funtioning. This time we released a newer version, which is binary incompatible to any previous version. The embedded core-loader from the MBR still needs to load some modules from /boot/grub/i386-pc . And this time those newer modules to load failed and you ended up at the grub-prompt.

I seem to be in the same boat (on another computer, MX19). During updates yesterday I was surprised to be offered some choice re grub, I chose boot partition, then continued using computer. Maybe I should have come on here and gotten advice before I proceeded?
On re-booting today I get the "grub rescue" prompt.
It's legacy, 64bit, HP. I usually boot in to systemd.

I don't understand a word of the above. What is MBR? I'm not criticizing, I am just not a developer, I enjoy using MX and have offered some help where I was competent to do so.
How do I get back to booting up? I still have the live usb if I need it.
Thanks.

edit: the message I get is

"GRUB loading.
Welcome to GRUB!

error: symbol 'grub_calloc' not found.
grub rescue> "

Boot the live USB, run tools - boot repair and choose MBR.

Ok, I'm at MX Boot Repair window - 4 options - do I choose "Restore MBR or PBR from backup (legacy boot only)"?
