View Full Version : [ubuntu] black screen with underscore after updating ubuntu on Lenovo G560

hello everybody, I'm new here. I looked for this problem online during the past few days but I haven't found a solution. I have a Lenovo G560 and I divided my hard drive into two partition, I installed Ubuntu on C:\ and Windows on D:\ and I haven't had any problem, but after updating ubuntu to version 14 my computer couldn't boot anymore. the bios loads and I see the Lenovo icon but then I just get a black screen with an underscore (not a blinking underscore), I tried booting from a bootable USB stick but the same thing happened (I put it as the first device to boot from in BIOS settings). can anyone please tell me what are my other options ? what should I try now ? thanks in advance and have a good day !
