[Bug 48266] Re: Ubuntu server kernel will not boot.

[PVi]

Like a flod, boot from the install cd and select "rescue a broken
system". Then follow the instruction until "Installing base component"
appears on the screen. After finishing this step, press ESC to get into
install menu and  select smth.like "manually select components to
install". On the next screen, the kernel list appears. Select the first
"linux-386". Then continue with install, reboot and enjoy. System will
use 2.6.15-23-386 kernel.

hope,this help.
