I have Ubuntu 14.04 installed on a Lenovo G580 laptop, and I am no longer able to boot it. I tried recovery mode normal boot and failsafeX but it still fails. When I just go through the normal start process, everything seems normal: I see the five dots cycling red-white, then a few lines of text, which the last line is 'Restoring Resolver State' ... and then a blinking cursor.
I also tried to see if I could fix the problem using Ubuntu 14.04 Live disk, but it doesn't recognize the existing install. I am also not able to access the existing files and folders when in Tyy Ubuntu mode. But I can access my files and folders via tty or root from the recovery menu.
Any ideas?
update: solved by by reinstalling 14.04 LTS which preserved /home... See Ubuntu 14.04 boots to black screen after upgrade from 13.10 - no display, problem seems to be X connected & https://help.ubuntu.com/community/UbuntuReinstallation for how to reinstall without losing your home folder
Thanks.
