Installing the new kernel will ADD the new kernel to your boot process and to grub. If it doesn't allow you to boot just select the old kernel from grub when the machine reboots and you can go in under the old kernel and find out what's up. If you want to then go back and always boot from the old kernel just change the grub configuration file to reflect your default kernel for booting.
