GRUB failure with zfs boot

[mahesh]

Hello,

I have an old Clevo W110ER that was working fine on Ubuntu Desktop installed from a USB stick. It runs a couple services in Docker like Home Assistant and MotionEye.

However, it won't boot anylonger and gives a grub error. I've run boot-repair from a LiveUSB but did not apply the auto repair. The output is below:

Is there a way to repair this?

Thank you for your assistance!
