multiple beeps in booting and choices of 2 centos(after updating)

i don't why am i booting 2 centos when my system boots. i remember i use yum update a couple of days ago and these options shows when booting up and it beeps multiple times.

one is centos-2.6.32-358.el6.x86_64
and centos-2.6.32-358.18.1.el6.x86_64

i dont know where did the other one came from.

the content of my /boot is:

config-2.6.32-358.el6.x86_64              symvers-2.6.32-358.18.1.el6.x86_64.gz
efi                                       symvers-2.6.32-358.el6.x86_64.gz
grub                             2.6.32-358.18.1.el6.x86_64
initramfs-2.6.32-358.el6.x86_64.img       vmlinuz-2.6.32-358.18.1.el6.x86_64
initrd-2.6.32-358.el6.x86_64kdump.img     vmlinuz-2.6.32-358.el6.x86_64
last week it happened to me and what i did is i delete the other config. and now ive just delete the other config-2.6.32-358.18.1.el6.x86_64 and reboot if it will work out but it didnt

Whenever you do an update that installs a new kernel, the OS retains the option to boot to the previous kernel as a fail-safe. You can remove the option in the /etc/grub.conf file. You can also use yum to remove the old kernel version AFTER you boot into the new kernel and ensure there are no issues with it or software that you run on your system. I would do some research on this to make sure you are aware of the implications of removing a kernel before you do it. It can have associations to software or configuration settings that you might have to modify/correct, depending on what you do with your system.
