I have Ubuntu Server 14.04 64bit installed on a Lenovo IdeaCentre Q190. The last kernel I could successfully boot was this one: linux-image-3.13.0-74-generic 3.13.0-74.118 However, with sudo apt-get upgrade, the following kernels have been released (and I've installed them) but they will NOT boot: 1) linux-image-3.13.0-76-generic 3.13.0-76.120 2) linux-image-3.13.0-77-generic 3.13.0-77.121 As you can see below, numerous kernels have been installed overtime, but the two above (the latest ones) do not boot. sudo dpkg --list | grep linux-image rc linux-image-3.13.0-39-generic 3.13.0-39.66 amd64 Linux kernel image for version 3.13.0 on 64 bit x86 SMP rc
