Issue
I compiled a linux kernel and installed it by using
sudo make modules_install and sudo make install.
After installing the kernel, I checked the following cfg file /boot/grub/grub.cfg to make sure the newly installed kernel is listed.
Although it is definitely listed in the grub.cfg file, it doesn't appear on the boot selection menu that appears at the boot up time.
Since I installed Ubuntu 14.04 along side with windows 10, I can choose between ubuntu and windows at the booting time. Is it possible to add a submenu of my newly installed kernel so that I can choose among Old kernel, New Kernel, and Windows 10?
Solution
Have you tried doing a sudo update-grub and when it refreshes does it show your kernel listed out in the terminal?
As for the menu, if you go to the advanced options in the GRUB menu, you should be able to select which kernel to use. This is when the GRUB menu shows up.
