Ubuntu does not boot

[zatix]

I just reinstalled ubuntu to the new version in my macbook pro, I have rEFIt which properly boots mac osx but for some reason it is not able to boot the new installation of ubuntu.

I made the common installation (ext4 partition mounting / and one for the swap), then I restart I sync the partitions with rEFIt and mac osx boots well but the ubuntu gets stuck and I never get to see the grub.

should I modify something else?

many thanks.

I installed the 64 bits version of ubuntu 11.04, is this ok?

Now I have the followving problem:

When I power on the macbook I hear a beep and I only see a black screen, I have to reboot four times to get to the reflt menu, I guess I broke the MBR, any idea about how to fix it?

this is my disk:

I updated the MBR and syncronized to the gpt but still I have to reboot 4 times to see the reflt menu, the disk looks like:

I vaguely recall hearing about the need to reboot multiple times as you describe being a symptom of firmware that's been damaged; however, my memory of this is rather foggy. You might want to investigate that possibility, though, and if you can find corroboration for this hypothesis, download whatever firmware update is available from Apple and flash it. Don't do this unless you can get corroboration, though; firmware update operations are a bit risky; if something goes wrong, it could completely brick the computer.

I am afraid this is my case as I reinstalled everything and tried so many things and I still have this problem, do you know where can I get this firmwire?

thanks

What is your exact model ? Link in everymac.com pls.

I fixed the issue by reinstalling again the firmware, I followed the instructions of this link http://pubmem.wordpress.com/2011/04/...-a-macbook-51/

Now I am running both linux and mac osx, thanks all
