How to install new kernel

[suvisuper]

Hi all ,

I have built a custom kernel for Ubuntu. Now I need to install it in my ubuntu 8.04 and need to boot from it. Could anyone help me with how to go about this. I dont know how to make the kernel boot up?

The current contents of the /usr/src directory are as below

root@lxdevenv:/usr/src# ls
linux-headers-2.6.24-23 linux-source-2.6.24
linux-headers-2.6.24-24 linux-source-2.6.24.tar.bz2
linux-headers-2.6.24-24-generic

Also in what format does the new kernel to installed need to be in?The kernel what I have built is as a executable.

Thanks in advance

If you google with term " Howto kernel compilation" should give you plenty of links.
I got this How To Compile A Kernel - The Ubuntu Way | HowtoForge - Linux Howtos and Tutorials for ubuntu .. though its pretty old doc --it should work. And here is my experience gET iT i sAY .giis - ext3 File Undelete Tool

The best kernel build howto that I've run across is the one found at Digital Hermit:

Digital Hermit - Kernel-Build-HOWTO

Hope it helps you.

Thanks for your replies 2 both of you. They have been very helpful . But I am getting a problem at the very end. "bash: mkinitrd: command not found" is what I get when I do mkinitrd at the very end.
Please help me as to how to install mkinitrd . My ubuntu version is 8.04 hardy.
I cant install it thru apt-get also

Thanks
