no kernel loading on grub
hi linux professionals =O
I had ubuntu 12.04 3.5.0-23-generic dual boot with win7 .but there was a problem to use ati/radeon fglrx on my system so i decided to downgrade kernel (because that driver working with kernel <= 3.4 ) .
I installed linux-image.3.2.0-23-generic and linux-image.3.2.0-24-generic on my system , and i used sudo update-grub to add those kernels to grub boot loader ,and output showed all kernels added to boot loader.
after restart there was just 3.5.0-23 on boot loader so i thought if i uninstall 3.5.0-23 grub can load other kernels ( Im taking shame =[ ) .I uninstalled linux-image-18.104.22.168generic via synaptic and after restart there is just these options on grub boot loader :
I used live usb to get this informations :
> # If you change this file, run 'update-grub' afterwards to update

there is nothing in /boot .

Re: no kernel loading on grub
when you install a new kernel, there are 4 packages to install : 2 headers & 1 or 2 images (3.2 might have only one)
the headers are needed to compile the graphic driver by the system
note: install synaptic for ease, and you can also install the "linux-image" metapackage to be sure having a complete installation
