Do you use grub or grub2 ?
I use grub. I`ve tried your method but I just don`t have enough knowledge to pull this one by myself. I went to Package Manager and found the grub files, but I just don`t know how to edit/remove previous versions of grub.
for example I have in my start menu (or GRUB Loader)ubuntu,linux 2.6.3-19-20-generic and some previous versions like ubuntu,linux 2.6.3-19-19-generic, 17, 16 and 14.I need step by step instructions on removing these files.
