Re: [fedora-list] How do a fix a non working kernel installation ?



Here is my grub file.  The boot partition is /dev/sda1.  That should
be hd0,0, right ?    The root partition is sda2.  That should be
hd0,1, right ?

Does anyone see anything wrong with my grub setup ?

I don't understand how installing an f12 kernel and then uninstalling
it could still result in a machine that won't boot.   Does f12 assume
an ext4 filesystem or something ?  df thinks my file systems are all
ext3.

Thanks
