I recently upgraded Ubuntu 10.10 from 32 to 64bit, but there are two entries I'd like to remove - they're the 32bit entries, with -pae suffix. There is even a initrd-...-pae image for them in /boot. Do you know how to clean this mess?

Rather than just deleting them (and thus confusing the package manager), uninstall the kernels you don't want to show in the GRUB list. Then run sudo update-grub to regenerate the list.

I would, but it won't show in synaptics. I've only got the one I'm running now. Can I delete the old kernels? If so, which files? – FLamparski Nov 21 '10 at 12:15
