Linux Grub Updating

Hello ;

  I have 32 bit 12.04 Ubuntu. I followed  instructions below  to  install a new kernel image:

*Install the xenomai kernel:
sudo dpkg -i linux-headers-3.2.21-xenomai+_0.1_i386.deb
sudo dpkg -i linux-image-3.2.21-xenomai+_0.1_i386.deb

*make sure it will show up as a GRUB-entry when booting:
sudo update-initramfs -c -k 3.2.21-xenomai+
sudo update-grub

*reboot. uname -r should now show: 3.2.21-xenomai+

But my grub remains same after these instuctions, also I have run the attached script.
What must I do? Thanks.

Hi,

If you don't see the item in grub after reboot then it seems that your step 2 is not running.
Will you post your /etc/grub.conf

The script has nothing to do with grub update. It is just updating some packages and installing some others.

Cheers,
K.

All right! It is under "Previous Linux Versions
Thank you Kerem, in Grub submenu of Linux Previous Linux Versions there were already  the name of 3.2.21-xenomai which I want to see in Grub menu. I was looking into main menu.
Problem dissappeared.
