Remove old Linux Kernels from Dualboot Grub Startup Menu using Ubuntu

First of all, determine which Linux Kernel version you are running using the command:
sudo uname -r

Then go to System ->Administration -> “Synaptic Package Manager”.

Search for “linux-image-“, arrange by installed packages (click at the column header most to the left) and then completely remove all linux kernels (linux-images) that are older than you current version.

Then run the command:
sudo update-grub
