Hi everyone,

I updated my KDE Neon last night with a 219MB system patch that required a reboot. The system rebooted and installed the patch. After the automatic reboot, the boot sequence crashes with the following series of error messages:

error: can't find command `U'.
error: can't find command `d?'.
error: can't find command `e'.
error: can't find command `?rZ'.
error: syntax error.
error: Incorrect command.
error: syntax error.
error: can't find command `t?d'.

error: can't find command `startswith?endswith'.
error: can't find command `old_driverZ'.
error: can't find command `new_driver?xorg?co'.
error: can't find command `

Has this happened to anyone? My system is now borked and I have no idea where to start fixing it. Googling the various errors has not helped.

Since I never see the KDE Neon boot logo, the system is crashing before it loads, which could mean it's a Grub problem. I can't boot in safe mode. The terminal is inaccessible. Strangely, my monitor goes into power save mode if I wait long enough and then it comes back to life after 15 seconds with no change on the screen.

Luckily my home partition is on a 2nd disk, but I don't want to reinstall Neon. Should I fix Grub with a boot disk?

Hopefully, someone can point me in the right direction.

Thanks for your help.
