First I would like to say that I am a new user of Ubuntu... euh... I would like to be a new user, but it doesn't work !
I have a Macbook pro with Lion on one side and I wanted to install Ubuntu 12.04 LTS. So I followed the instruction of the Ubuntu website and everything seemed to work fine.
But now. when I start my computer, I have this message appearing on a black screen : "error: invalid arch independent ELF magic. grub rescue>"
I tried this : http://ubuntuforums.org/showthread.php?t=2120477
I also tried to launch boot-repair from my Ubuntu-Cd. In the two cases, the answers are positives : Boot-repair said that it has been repaired and when I type the two lines of the thread that I have mentionned the terminal says something similar.
But when I reboot... same error message.
Is there someone there that could help me ?
Maybe this could help to help me, it is a page generated by the "Boot-repair" app : http://paste.ubuntu.com/5594912/
Thank you very much !
Have a nice day,
