If you have just compiled a new kernel and want to be able to use it, you will need to add a new GRUB boot option.
A similar process should be followed if you have both Linux and FreeBSD, NetBSD, or OpenBSD installed on your system and want to be able to choose one of them at boot time. To set this up, follow these steps:
Once you have created a new kernel boot option, you can edit it by clicking on its icon on the module's main page. On the editing form, any of the fields can be edited and the changes saved by clicking the Save button, or the kernel can be removed by clicking Delete instead. Always be careful editing any kernel configurations that you did not create yourself, as a mistake may make the system unbootable.
