Use the 40_custom file, renumbering it if you need to change the order. |

Or you can replace 10_linux with your own script. It's just a shell |
| 25 |
script that spits out menuentry stanzas. 10_linux is quite complex |
| 26 |
because it has to handle everything, but something customised for your |
| 27 |
own needs can be much simpler. |

Or run grub2-mkconfig then hand edit grub.cfg to add the extra entries. |

There are always plenty of choices with GRUB. |
