    I recently been adding things to my nvram and I think I broke it for good. I have one of those Mac Book Pro 8,2 with El Capitan 10.11.5 and I was fixing the problem described here (I have one of those toasted discrete gfx cards)

    And it did work once I was able to boot with the Intel 3500HD, was so happy, but then something weird happened: the system won't boot at all, It gives up when it tries to boot and no kernel panic is shown .Probably kernel is not even loaded

    devfs_kernel_mount: kernel_mount failed: 2.

    I think I either messed with files on my partition or with nvram partition How can I know why do I have this error? I can't really reinstall the system because the installation CD won't switch to graphic mode, if this is a corruption of my filesystem..

    The only way I boot is in the recovery mode single user..or archlinux boot
