boot menu clarification

[sparth5]

I installed fedora 12 on my new laptop with windows XP as other OS on the dual boot.
When I boot I see three different things to select

fedora (2.6.31.12-174.2.22.fc12.x86_64)
fedora (2.6.31.5-127.fc12.x86_64)
other

I wonder why two listings show for fedora? I appreciate if some body can help me in figuring this out.

Thanks

The kernel on top is a newer kernel version, so you've apparently upgraded the kernel at some point. The system usually keeps the older kernel during upgrades just in case the new one doesn't work for some reason.

You can keep both kernels, or remove the older kernel if you won't be using it any longer.

How to remove the older kernel which I don't use it any more.

Open up a text editor (vim, nano, any will work) and remove the older one. If you prefer, gedit or kate are easy to work with.
This has to be done as root or sudo.
Example would be:

gedit /boot/grub/grub.conf

Delete the entry, save and exit.

Jay's suggestion will remove the entry from the grub menu, and to remove the kernel itself, you should be able to use yum with a command like the following:

yum remove kernel-2.6.31.5-127.fc12.x86_64
