First we should be aware of release Linux kernel version, hence check the same in the main Linux Kernel website:
www.kernel.org. Here we can see the recent stable kernel version(s).
In this case as you can see in the below screenshot it is Linux Kernel version 4.14.11.
We have now two ways to do the same:

- we can directly install .deb files of a kernel which is pre-compiled

Now we can check if they are successfully installed as shown below:

choose/select kernel version 4.14.11 and press enter to boot into the same. The system should load successfully newly installed Linux Kernel version 4.14.11.
