You need to tell us more. We cannot answer your question without knowing what boot loader, what distribution, what method of kernel upgrade. With only the information you've provided, the best that can be said is that you CAN have your old as well as your newly installed kernel available at the boot loader. You would simply select which to boot. In fact, that's recommended procedure. Don't ever throw out what is known to work until you know the new thing also works.
