I don't think you meant that---you can't have 2 kernels running at the same time.

Look at the GRUB configuration file (typically /boot/grub/menu.lst, but sometimes .../grub.conf) This tells you the name of the kernel file that will be used. I typically always alias the file to a generic "vmlinuz". I never change the config file, only the alias (link).

Depending on the kernel, you may also need to build a new initrd file.

only one kernel can be running at one time. you can remove the kernel reference from your boot loader. eg if using grub edit the menu.lst file deleting the entry you dont want.

if you did a make install - you dont have anything really ro worry about other than the old kernel image - which you can easily delete by hand.
