Fedora (3.9.5-201.fc 18.x86_64)
and
Fedora
then after there's fedora advanced and windows 8 (sda1)
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
these last kernel, don't work for me, i must use 3.6.10-4.fc18.x86_64 but ever want to start my system with 3.9.5
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.
