I've finally got ubuntu 12.04 installed as a dual boot but am having trouble getting it to start. I get to the GRUB screen and select ubuntu but it just goes to a black screen. The only thing I can do from here is to press ctrl+alt+del to re-boot it, but just keeps happening over and over. it also happens if I pick windows or ubuntu recovery mode. Any idea how to fix it? TIA

What method did you use to install Ubuntu? –  BiggJJ Jun 28 '13 at 9:00
    
I just ran it off a USB and installed it like that, using the 'alongside windows' option and just followed the prompts –  lexic Jun 30 '13 at 6:38

Boot into a live CD and run this code:

sudo apt-get install boot-repair
sudo boot-repair

Choose the recommended repair and follow the instructions you are given. Once boot-repair is done, reboot and see if Ubuntu starts correctly.
