See The Changes
Unfortunately, you will have to reboot your computer to see the changes. the new kernel shall be visible in GRUB menu during bootup. Generally, GNU/Linux does never need to reboot for software, library etc et al to work after install. But kernel will be an exception.# in rare case if it does not appear or update the grub menu itself:
sudo update-grub
note: this method will work on ubuntu and its derivatives.
