<div dir="ltr"><br><div>Dear Arindam,</div><div><br></div><div>What I understand is, your system has two Ubuntu 12.04 installations side by side. Are you using any one of those two to compile the 2.6 kernel? If so, then executing "<b>sudo make install</b>" will copy the kernel vmlinux, initrd and System map files to /boot directory and trigger an "<b>update-grub</b>" to rebuild grub menu. Your new kernel should appear afterwards. May be you are not being able to see the kernel listing because of having a ZERO timeout in GRUB menu which is causing it to boot to the default one directly. Make sure it is not the case.</div>

</div> Now , when I boot the machine and try to boot with the 2.6 kernel, I can't do that and Grub is not even mentioning that particular version of the kernel. If any help about this issue is possible , please drop me a mail. <br>
