Actually, if only your bootloader (well, I should say your MBR) didn't update, then you shouldn't be able to boot anything -- when you formatted the hard drive installing RedHat, it should have deleted the old kernel's image. And yet that's what's running.
Hmmmm... I guess what I'd do is a reinstall of RedHat 8, and tell it to format your root partition before it starts copying files. If you have important stuff to save, burn it to a CD-R first, or put it on another partition. What's your partition setup look like? Is /home a separate partition from the root? If so, you can put important stuff in your home directory, and then not format /home (but you'll still want to format everything else). Then reinstall RedHat 8.
