How to change kernel version in ubuntu?

Ask Ubuntu Asked by Ajay Bodara on December 27, 2021

I have already installed

  1. 4.15.0-112-generic
  2. 5.3.0-1023-aws
  3. 5.3.0-1030-aws

But when I execute uname -r that time shows only this one 5.3.0-1023-aws
I want to change 4.15.0-112-generic instead of this 5.3.0-1023-aws
Because this command is not executed in my ubuntu
enter image description here

Please fast to solve this problem give me a proper guideline of this
