This (from info grub) may help, depending on how the kernel fails...
     # Fallback to the second entry.
     fallback 1
                                                                                

   If, for any reason, the default entry doesn't work, fall back to the
second one (this is rarely used, for obvious reasons).
                                                                                

fallback
--------
                                                                                

 - Command: fallback num
     Go into unattended boot mode: if the default boot entry has any
     errors, instead of waiting for the user to do something,
     immediately start over using the NUM entry (same numbering as the
     `default' command (*note default::)). This obviously won't help if
     the machine was rebooted by a kernel that GRUB loaded.
