I have built kernel from source (3.16 version kernel source taken from kernel.org).

I did all steps of kernel compilation including 

sudo make module_install

Then I copied the bzImage formed with the downloaded source to /boot folder. ( I have multiple ubuntu versions installed on multiple partitions, and boot is not a separate partition but as a directory in every root file-system ).

I am now unable to get the new kernel image option in grub boot loader. I have executed also below command, but could see no modification in /boot/grub.grub.cfg

sudo grub-mkconfig

  • Try this method. – Doug Smythies Apr 23 '17 at 15:22
  • @Doug Smythies , Thank you for the answer and time. I got the answer, I have missed one step - "make install" which did update boot directory with updated kernel image and initram. The page you had mentioned seemed some different approach, haven't tried that as of now... – DevBee Apr 24 '17 at 13:56
