I have installed ubuntu 11.04 on my system.
After this when I used to give uname -r it showed me kernel version as 2.6.38.
Now I had downloaded kernel 2.6.34.12 from kernel.org and installed it using the following steps:
make
make modules
make modules_install
make install
This created files:
System.map-2.6.34.12
vmlinuz-2.6.34.12
config-2.6.34.12
In /lib/modules also I can see the new kernel 2.6.34.12 folder.
Next to create initrd.img I fired:
update-initramfs -c -k 2.6.34.12
Then I checked the grub.cfg and it showed me an entry for 2.6.34.12.
Next I updated grub:
update-grub
But after reboot uname -r still shows me the previous version 2.6.38.
What is the issue and why new kernel version is not installed?
This is why I dislike the excessive automation ubuntu's put in the process, none of those commands are standard so we can't tell if you're using them right, and there's little way to tell whether they even succeeded, or what success even means...
What did your grub.cfg actually look like in the end?

Thanks coronna for the reply.
grub.cfg contents are as follows:
