    Virtualbox won't load Ubuntu after upgrade to 12.10

    I have a dualboot setup with Windows 7 as my host CPU on Hard drive #1 and an Ubuntu partition on Hard drive #2. I installed VirtualBox (v4.2.18) on the Windows 7 OS and had everything working with this configuration. I decided to upgrade from Ubuntu 12.04 to 12.10 and that broke everything, starting with the boot loader. I believe the Grub --> Grub2 upgrade broke my boot loader. I was able to recover from this and I have both OSes booting individually.

    However, Virtualbox (run from Windows 7) does not work. The grub boot loader menu shows up, I select Ubuntu, and then I get black screen forever.

    In order to get Ubuntu 12.04 to work with Virtualbox on Windows 7 I had to follow these steps:

    When I redid all of these steps from scratch after the Ubuntu 12.10 upgrade I was no longer able to boot.

    I also tried purging Virtualbox from my Ubuntu install and reinstalled it but that did not help. I also tried creating a new virtual machine.

    I have done a ton of research online and in the forums. Nothing seems to work.

    Any ideas?

    I have an update. I mentioned that the GNU Grub boot loader does appear. Well I have these options:

    Advanced options for Ubuntu

    Under Advanced options for Ubuntu are the following:

    Ubuntu, with Linux 3.5.0-41 generic
    Ubuntu, with Linux 3.2.0-31 generic

    If I select "Ubuntu, with Linux 3.2.0-31 generic" Ubuntu actually boots! However, it feels REALLY slow and says "Loading initial ramdisk" as it is booting. The 3.5 version however fails to load.

    Am I close?
