Yesterday I wanted to update my 16.04 Xubuntu. When I ran sudo apt update && sudo apt upgrade (system wasn't able to complete the upgrade process), the system froze and I had to restart by force.

But now I cannot even start the system anymore. After each reboot, only the grub terminal is shown. I also cannot access the grub menu by pressing ESC key (my system is UEFI).

Do you have any suggestion how to fix this?

Boot from a LiveCD, and then there are a number of different methods you can use to troubleshoot and repair your boot loader.

I've never used it, but Boot-Repair is one such method, and looks promising.
