    My computer is a boot loop thanks to my really stupid error using Terminal. I was trying to flash an OpenElec image on a USB drive but I accidentally flashed it on to my startup disk, disk1, which caused some major issues. here is the link to what I was trying to do: http://wiki.openelec.tv/index.php/HOW-TO:Installing_OpenELEC/Writing_The_Disk_Im age#tab=Mac_OSX
    Instead of writing it to disk3, I wrote it to disk1 using this command : sudo dd if=OpenELEC-Generic.x86_64-5.0.0-efi.img of=/dev/rdisk1 bs=4m

    Repair Disk does not work, I don't have a backup so I can't just reinstall the OS X without losing all my data? I tried using Target Mode, I able to view the HD on another Mac but all my photos are in a iPhoto library (120GB) which cannot be opened or copied due to Error -36. I tried importing the file into iPhoto on the Target Mac but get an error that iPhoto disk is full. We cleaned the Target Mac iPhoto library completely. The photos are the last 10 years of our life so we cannot lose them.

    Is there a way to remove the image that I installed on the HD via Terminal so it will start up again? Can I somehow Target Mode transfer the photos onto to another Mac?

    Please help me!

    Boot into the recovery partition and reinstall OSX.

    I figured out a way to retrieve the photos, view the iPhoto library file on the Target Mac, right-click or control-click on your photo library file and select “Show Package Contents” from the list. there a folder in there called Masters.
