removing an Installed Kernel

I have compiled and installed a kernel,

Now it fails to Load...and i want to remove it....

what is the procedure to be followed, I have installed GRUB 1 on my system fr simplicity during this process.

Hello.

Just delete the kernel image and the initrd files from /boot and delele the entry in /boot/grub/menu.lst (in the entry you can find the file names).

In grub2, you would just delete the image and do an "update-grub2"

and remove the modules that you install with make modules_install from /lib/modules/<kernel_version>

but take care to not remove the wrong directory!

For the future it may be advisable to use a build-script that builds you a package that can be installed using your distributions packaging system. In example for a Debian based (apt) system you can use make-kpkg and in addition of getting a kernel image and modules you get a package that can be installed and removed using apt (I am sure that there is a comparable tool for any other major distribution as well), so your workflow looks like this:

make menuconfig
CONCURRENCY_LEVEL=8 make-kpkg --initrd kernel_image dpkg -i ../linux-image-<version>_<arch>.deb

this even adds an entry to the boot-loader for you. and then you can just as easy remove the kernel using:

dpkg -r linux-image-<version>

and the kernel is cleanly removed from your system.
