If only the oldest kernel works, try this in a terminal as root, without the quotes: "yum remove kernel*" because yum will never remove the running kernel. (I know, because I''ve had to do it.) Also, note that I didn't specify -y because you'll want to look at what's being removed and make sure it's doing what you want.

This is normal, and expected. Fedora, like most Linux distros, keeps the three most recent kernels available. This way, if you have trouble booting after a kernel update you have two others that are known to be good. Once you have those three, the oldest will be removed every time a new one is installed.

In order to see the last kernel installed inside "Fedora", you need to regenerate the Grub config file:

# grub2-mkconfig -o /boot/grub2/grub.cfg

Then restart and you will see something like this in Grub menu:


Advanced options for Fedora

Windows 8

To be clear, this shows you the recently installed kernels because it completely rewrites your boot configuration, and along the way it detects your kernels. There are probably better ways to list the installed kernels, but this is the best way to automatically rebuild your boot menu
