Last time i turned on my computer, ubuntu didn't boot completely, and I got a black screen and a terminal! I tried to fix the problem but it didn't work, so I tried to repair it using live usb. After I rebooted the Pc, now it's showing the gnu Grub menu! And I have no idea what to do! Help me please! Thank you! Repair URL: http://paste2.org/MmsUNXz9
From your boot-info-summary:
Script `/boot/grub/grub.cfg.new' contains no commands and will do nothing Syntax errors are detected in generated GRUB config file. Ensure that there are no errors in /etc/default/grub and /etc/grub.d/* files or please file a bug report with /boot/grub/grub.cfg.new file attached.
Have you made any changes to the mentioned files?
Check your filesystem from live-USB with
sudo fsck /dev/sda1
Check your hard-drive from live-USB with Smartmontools
