remove old kernel

[valemon]

After installing a newer version of kernel the old one still shows up in grub. Should I remove the entry only from grub or should I remove the old kernel completely? The last how can I do it?

if new kernel is working fine and you want to free up some space, un-install old kernel through YAST or 'rpm -e' command.
un-install will remove entries from menu.lst too.
OR keep old version too and put # signs before Old Kernel's title block in menu.lst file.

I tried through yast and the only kernel showing up is the new one. However I can boot to the old kernel. So where is the old one?

try to uninstall through 'rpm'.

rpm -qa | grep -i kernel
rpm -e kernel-{VERSION}
