    Did you try to install Windows or Linux on your Mac. As far as I know, Macs do not show messages on failed boot up. They just display a picture. Windows will show a similar message to what you posted. I don't know about Linux.

     

    It appears the OS X partition is damaged and cannot be used.

    Did you ever install the Firmware update to allow your Macbook Pro to use Internet Recovery? If not, then you will have to use the disks that came with your Mac to boot and possibly repair the disk using Disk Utility.

    My guess is your ultimate resolution will be to erase the drive, reinstall the original OS that shipped, then upgrade. After that, restore from your backup.

    Just to add to what Barney said. There are no "Startup Key Combination Keys" for OSX. Just a power key or button. Same with most Linux and Windows laptops.

    There are no "Startup Key Combination Keys" for OSX.

    I was thinking that meant, Cmd-R, Cmd-Opt-R, Opt, X, Cmd-V, Cmd-S, Shift

    Its not listed -- but sometimes documentation is inaccurate --   Try holding down the option key after the chime - that will let you select the startup drive.

     

    Your apple may have lost this info in your System Preferences - so it can't find the drive-happened to me during troubles where I reset the PRAM - then the preferences would not have a startup drive marked.

     

    Don't know why they would drop it when there are users you run multiple releases on their mac.

    The combinations are used after the chime - so you power up - hear the chime -- and press the key combinations.

    It is showing "no bootable...!" problem after install paragon NTFS software for my Samsung External HD.

    I would like to restore previous state from my Time Machine Backup. I can't press any startup keys.

    Pls tell me, do you have any suggestion to get back previous state?
