Thanks for quick reply. So there are not a ton of config files I need to worry about causing problems? It sounds to me like I can delte everything that refers to the kernel version numbers I installed. I still am not sure about /usr/src/linux That has been changed to a symbolic link that points to the last kernel I installed. I want to delete that kernel. Should I delete /usr/src/linux also or make it point back to the stock kernel that came with my system? Before I installed these other kernels my /usr/src folder was very clean and tidy and just had a /linux folder in it and a sources folder in it. Now the names of the original kernel have been changed. Should I rename them also?
Thanks for your help and advice. I appreciate it
