Syntax errors are detected in generated GRUB config file.
Ensure that there are no errors in /etc/default/grub
and /etc/grub.d/* files

------------------------------

This probably means you made a mistake when editing /etc/default/grub.
Please attach copy of /etc/default/grub if you cannot find the error.

Also note that you are still booting into the 6.14 kernel from Ubuntu
25.04
