    Actually, I would have done the same thing. Compared with the alternatives, it's not that lame IMO. What stopped me from doing this was the other problem I hit - my graphics card sends all output only to the external monitor. So unless I have a second monitor hooked up to my iMac I see nothing but a blank screen.

    Re: Ubuntu on MacBookPro - difficulties w partition tables

    It seems that the installer isn't installing Grub2 correctly when I follow darkvad0r's instructions for lack of a bios-grub partition. Does anybody know more about this? I've tried and re-tried this a few different times and I'm getting a fail for all of them.

    We're now almost in 2012, but the post (#26) of cath0dez saved my life while trying (really hard!) to install dual boot MacOS (Lion) / Ubuntu 10.04LTS on my MacBookPro2,1.

    Many, many thanks, because I followed that documentation: https://help.ubuntu.com/community/Ma...elInstallation

    Everything went fine until the "freezed linux" on the final reboot. This documentation states to try to restart again. I did not work for me:

    I tried to reinstall once again following cath0dez's instructions and it worked. I was especially the step 7 were it was more precise than the general howto.

    THANKS!

    Partition table entries are not in disk order
    I am attempting to install Ubu 12.04 on my MBP 8,1. When booting to Ubu from rEFIt, i get a line of text telling me "No operating system found" I assume this is a problem with the MBR.

    Attempted to correct the partition table using rEFIt, but that failed, so here I am. I read the first few pages of this forum, and observed the output David got, as shown in the quote. He clearly has two overlapping MBR partitions. However, when I run the fdisk list tool, my partition table does not appear to over lap.

    The fdisk output is as follows:

    Re: Ubuntu on MacBookPro - difficulties w partition tables

    My MBP 7,1 runs on Mountain Lion. Anyone can guide me how to use VirtualBox to run Ubuntu 12.04 on it?
