thanks all of you first I just want to point that nothing is available in /usr/src/ for that specific kernel and I found that the best way to remove a kernel built by me is to remove /boot/vmlinuz*KERNEL-VERSION* /boot/initrd.img*KERNEL-VERSION* /boot/System-map*KERNEL-VERSION* /boot/config-*KERNEL-VERSION* /lib/modules/*KERNEL-VERSION* and after that update-grub2 thanks in advance for your time giving me a clue ^_^ _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
