Grub – How to Add New Menu Items to Grub Boot Menu

14.04grub2

I need to remove one existing boot menu item and add two new ones related to my second disc partitions in my Grub menu. What is the best way of doing that?

Grub menu entries are auto-generated by sudo update-grub. Have you tried to run it ? Doesn't it suite your needs ?

Otherwise, you can use /etc/grub.d/40_custom to add your custom entries. And then run sudo update-grub to update /boot/grub/grub.cfg.

You can however edit manually /boot/grub/grub.cfg to delete an entry. But your change will be lost the next time update-grub will be run by you or automatically by ubuntu when there is a kernel upgrade.
