    Hi,

    I'm attempting to install OSX Lion 10.7 GM on my 2011 Macbook Pro 13".

    I've used DiskUtility to write the InstallESD.dmg to a USB stick.

    When I attempt to boot from this, I get the gray screen with the spinning indicator.

    Then, after a while, it displays a circle with a line through it. The spinning indicator underneath is still spinning, however, it doesn't seem to boot beyod that point.

    Any idea of what's going on?

    Cheers,
    Victor

    heya,

    Hmm, I did restore it.

    As in, in Disk Utility, I went to the "Restore" tab.

    Then, in source, I selected the InstallESD.dmg file.

    For Destination, I selected the USB stick in question.

    Also, if I open up the USB stick in OSX I can see installer files on it, so it seems to be created correctly (at least from what I can tell).

    It's just it keeps going to that circle with a line error screen whenever I try to boot it.

    Cheers,
    Victor
