good day
um 16.04 64bit
i was trying out vertialbox and it installed:

grub menu :

4.8.0-53-lowlatency
4.8.0-53-lowlatency (upstart)
4.8.0-53-lowlatency (recovery mode)

4.4.0-137-generic
4.4.0-137-generic (upstart)
4.4.0-137-generic (recovery mode)

i would like to uninstall :

4.8.0-53-lowlatency
4.8.0-53-lowlatency (upstart)
4.8.0-53-lowlatency (recovery mode)

and go back to :

4.4.0-137-generic
4.4.0-137-generic (upstart)
4.4.0-137-generic (recovery mode)

4.8.0-53-lowlatency does not boot , but 4.4.0-137-generic will boot.
how do i uninstall 4.8.0-53-lowlatency kernel safely ?

dpkg -l | grep linux-image to get a list of the kernels installed.
then
sudo dpkg --purge linux-image-4.8.0-53 (the exact name of the kernel to remove)

dpkg: warning: ignoring request to remove linux-image-4.8.0-53 which isn't installed
it is showing up in grub menu but it isn't installed ?

dpkg -l | grep linux-image
ii linux-image-4.8.0-53-lowlatency:i386 4.8.0-53.56~16.04.1 i386 Linux kernel image for version 4.8.0 on 32 bit x86 SMP

pavlos_kairis this seemed to work though

open synaptic
search for linux-image
linux-image-4.8.0-53 completely remove ,purge
sudo update-grub
