I have compiled a kernel ( on ubuntu 10.04 using the
command :
fakeroot make-kpkg --initrd --append-to-version=-new-kernel kernel-image kernel-headers

a grub.cfg file is generated on compiling the kernel.
but on rebooting my new-kernel name is not displayed on the grub's menu.
The grub doesn't get updated even after running the update-grub command. The desired kernel name is listed on the terminal on executing the update-grub command, but on rebooting the grub menu doesn't show the newly compiled kernel's name.

Please help me out with this..!!!!
