This is not the recommended approach. Use /etc/grub.d/40_custom to add any |

bespoke entries. However, the GRUB2 OS-prober should pick it up on its own. |

It may be worth re-installing GRUB2 in case something has gone askew, or |
| 23 |
booting from a LiveCD and running GRUB from there to find out what it sees, in |
| 24 |
case your GRUB installation is corrupted. |
