    Hi there,

    I just tried updating to El Capitan. However, my battery has died during the installation process. I was warned to plug my charger in before updating, which I had planned to do, but I got distracted and completely forgot about it. Now, whenever I turn my MacBook on, I can login, but I soon get an error page and my computer turns off.

    Is there any way I can continue the installation process? I am really concerned as I have a lot of important files which I fear are now lost. I went to Disk Utility and tried repairing the disk permissions, but this didn't do anything. If my only option is to reinstall the OS, is there any way I can move my files to a hard drive?

    I have a 2011 MacBook Pro, which is out of warranty. I can see Apple has a paid helpline - is this worth it, or are they just going to tell me to reinstall it?

    Any help on this would be greatly appreciated.

    Regards

    I believe there is a recovery mode (I seem to remember it was pressing cmd+R while booting). Maybe in that menu there is an option to repair, or update or something (I don't know for sure as I've deleted my recovery partition, and always use a USB installer - I don't know if the menus are the same).

    Does anyone know if the recovery partition can help him?


    PS: I would avoid testing things out in the recovery partition until someone can provide a clear answer.

    If you have another mac you could try "target disk mode" to recover / copy / back up your files first. Hopefully you can recover your files and then do a clean install.

    Some days it is best not to play with power tools.
    You can hurt yourself.

    Thanks for the replies. I was wondering, I was to reinstall OS X in the recovery thing, will that just install a new copy of OS X, or will it delete all my files too?

    in recovery hd, you have a few options: 1-reinstall OS (that will keep all your files)
    2-erase disk and install OS
    3-restore from back up
    option no1 for you
    Or, like someone mentionned, "target disk mode", if you have access to another mac

    I just reinstalled the OS in Recovery, and it worked fine. All my files were still there once finished.

    Hello Everyone,

    Firstly, thank you everyone for posting this thread. I had the same exact problem and now it's solved.
    Just want to add a small additional details here; In case any of you experiencing same situation.
    When I realized that my computer shuts down, I turned it back on and only grey screen pops up with apple logo and download bar showing 3/4 full. No apple start up sound...nothing. Bar also not showing any progress. Tried shutting down again few times and same results.
    Then I came across this thread then I tried doing : https://support.apple.com/en-us/HT204904 and it worked out !!
    But note this :
    1. Even if your macbook didn't make the classic apple start up sound, go ahead press the Command + R button immediately after letting go of Power button, and keep pressing it until the apple logo shows up. Then keep pressing for another 5 second
    2. Wait. do not power down again if it's taking a while to display any prompt window. Some case might take longer then the other. My recovery menu shows after about 10 minute; I was about to gave up when it finally shows up.
    3. Choose Reinstall OS X or use any other option as needed.

    I hope this small tips helps...
    Now I'm glad I don't have to take my macbook to a repair center, Thanks to you guys.
    Stay cool ! CHEERS !
