At one point, simply ceased to boot ubuntu :
in Grub choose Ubuntu and after a black screen with a blinking cursor.
Googled everywhere as a solution to offer or to add cmdline options In the startup parameters or through the recovery mode boot. Neither are not working.
The funny thing is when you try to run it from a live CD or USB drive-same problem . Blinking cursor after selecting the option run. Windows with normally working.
What the problem might be?
Problems to look for in the logs.
Usually this is the problem with firewood for the video.

Solved the problem. Launched the ancient core that was in the system and Ubuntu started.The profile really didn't get to go... Pressed ctlr+alt+F4,logged, executed update-grub , rebooted and worked.

First problem: question. Where iron (especially video). Where are the logs? Put the new kernel? Why is this not said in the question? And so: "I have something does not work, help with something" and I have a question for you more than you have to Linux.
