MacBook do not boot

Hi there, had 2 days that suddenly my MacBook won't start.
I have a dual boot, and I was using an EFI partition to boot windows 8.1 and a ssd for mavericks.
Everything was working fine.
Now, every option that I try command+r, command+s or alt,  stuck in a gray screen with a prohibit sign with a loading above.
I just want to erase all my data and install the mavericks again, most of my docs are in Dropbox. So I just want to work again using my machine.

When I press CMD+D the MacBook goes straight to automatic repair on windows 8.1.
I'm using an external DVD player trying to re-install lion. In my setup I have two internal HDs:
120SSD that was installed Mavericks
320gb that I installed windows 8.1
Now, I cannot run the utilities from MacBook, or see the option to install by an external DVD player.

  • My Macbook will not boot the operating system.  It just goes to a blue screen after the apple logo and the spinning wheel goes off.  I took the battery out and held the on/off button for five seconds and reset the PRAM.  I have the old mac os disk.

    My macbook will not boot.  It goes to a blue screen after the logo and wheel goes off.  I have taken the battery out and held the on/off button for five seconds and reset the PRAM.  I have the the original os disk but have not put it in for fear of losing un backed op data.

    You won't lose any data unless you erase your hard drive.
    Put your install DVD into the optical drive and reboot. As soon as you hear the boot chime, hold down the "c"key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the install DVD in the optical drive.
    When it does start up, you'll see a panel asking you to choose your language. Choose your language and press the Return key on your keyboard once. It will then present you with an Installation window. Completely ignore this window and click on Utilities in the top menu and scroll down to Disk Utility and click it.When it comes up is your Hard Drive in the list on the left?
    If it is then click on the Mac OS partition of your hard drive in the left hand list. Then select the First Aid Tab and run Repair Disk. The Repair Disk button won't be available until you've selected the Mac OS partition on your hard drive. If that repairs any problems run it again until the green OK appears and then run Repair Permissions.

  • Macbook will not boot up after running Software Update

    My MacBook will not boot up after running Software Update (Security update + Java?) earlier today. I have only the gray start up screen + Apple logo + gear wheel constantly rotating. I have tried restarts several times and tried to start up from my original system DVD - this makes no difference.
    I called Apple support, tried resetting the power and PRAM - still no difference. He had no knowledge of other problems reported; although I note recent post may have same issue.
    I cannot get an appointment at my Apple Store before Monday.
    Any suggestions?

    Still no success. When I hold down the option key when powering up I get the hard disk icon plus arrowhead (only). When clicking the arrowhead it goes to the gray screen + apple logo+ rotating gearwheel.
    This happens both with DVD in slot and without DVD. the DVD image is not coming up on screen. When I start up without DVD the hard disk icon appears promptly. When I start with DVD in the DVD is spinning for a short period before the hard disk icon appears. On clicking the arrowhead to hard disk icon the DVD spins again for a while then stops. Apart from the DVD spinning, both situations result in gray screen + apple logo+ rotating gearwheel.

  • After updating Airport software, Macbook will not boot

    I see others have updated with the new Airport software without incident, but not me.
    I just ran software update to install the Airport update (hoping it would cure the problem I've had -- and other users as well -- with the connection dropping every 5 minutes with Linksys routers [check the Airport discussion board for much discussion of this]).
    After installing, upon restart my Macbook will not boot fully. I get the Apple symbol, then the spinning gear symbol, then a light blue screen and that's it. After a while the fan comes on.
    Call it the light blue screen of death.
    All was working fine until the update.
    I have boot camp and I can boot into Windows.
    I have tried removing the battery and resetting the PRAM. No help.
    Sigh... Applecare is closed so I cannot call until Friday morning. Anyone have any suggestions of what I can try?
    I have my Mac hard disk backed up from a few days ago using Super Duper on a USB drive but I am reluctant to try booting from it as I fear corrupting the drive. Unfortunately I don't have my Mac system CDs with me as I am away from home at the moment.
    I just switched to the Mac 6 weeks ago after 3.5 years with a Dell laptop. Never had a single problem like this in all that time. But I still like my Mac.
    PD

    Well, I spoke too soon. Last night I was able to start up as described above, but this morning when I tried to start it did not even get to the Mac symbol. It just hung at a dark blue screen for several minutes.
    Tried restarting with the shift key held down but it would not go into safe mode. Just the dark blue screen.
    Resetting PRAM made it startup.
    But I'm pretty nervous about this.
    So, is there a way in Mac OS X to roll back to the system before the update? In Windows XP this is very simple under System Restore. I have the impression OS X doesn't have this feature and won't until next year with Time Machine.
    And I see now I'm not the only user with this problem.
    PD

  • HT1366 Macbook does not boot green light flashes for few secends

    My MacBook do not boot when I press power button. The green light on the side flashes for few secends.

    Dear Apple-Friends! Dear Imola!
    Thank you so much for your Memorial Day Super Fast Answer. Nothing has helped though and right now the support line is closed as it is 11:10 p.m. local time. will call them tomorrow morning and see what we can do. But this ***** so much, I waited 2 weeks for the machine to arrive, almost two weeks 'cause I bought it the moment it arrived in the online store.
    I called Apple USA but they are closed because of Memorial Day. ;-(
    Tough luck, I guess!
    Cheers,

  • Macbook will not boot, makes clicking sound

    When I power up I get a blank screen and I hit clicking but the macbook does not boot up. I think it is not finding the HDD; happened before and there was a combo of keys I hit when I hit the Power button that found the HDD.
    Any ideas?
    Appreciate any help
    Thanks, Ralph

    Hi,
    To get your mac to boot from the install disc simply insert it then turn on your mac holding the option key(the alt key), then select the disc in the menu.

  • It rained in my window last night, on my power strip.  My macbook adaptor (charger) and iphone adaptor were both plugged into the strip.  The power strip is dead.  Iphone is fine.  Macbook will not boot up and charger light doesn't go on.

    It rained in my window last night, on my power strip.  My macbook adaptor (charger) and iphone adaptor were both plugged into the strip.  The power strip is dead.  Iphone is fine.  Macbook will not boot up and charger light doesn't go on. I borrowed another charger and still no luck.  What should I do?  (Charger wasn't plugged into Macbook until I dried it off.)

    Spill Cleaning
    And, don't think that just because it was two teaspoons and not a glassful that there is a difference.
    Some liquid has just spilled into your Mac. What should you do?
    Do
    Immediately shut down the computer and unplug the power cord.
    Remove the computer's battery (if you can)
    Disconnect any peripherals (printers, iPods, scanners, cameras, etc.)
    Lay the computer upside down on paper towels to get as much liquid as possible to drip out.
    Note what was spilled on your Mac.
    Bring the computer into an Apple store or AASP as soon as possible.
    Don't
    Don't try to turn it back on. Liquids can help electrical current move about the components of your Mac in destructive ways.
    Don't shake the computer (this will only spread the liquid around).
    Don't use a hair dryer on it (even at a low setting a hair dryer will damage sensitive components).
    Do not put in a bag of rice in as much as rice will get into the ports and optical drive and do further damage.

  • Hey ppl,my macbook is not booting and by that i mean u can hear the audio wave when its starting up,the screen goes white and then after a while there's a folder with a question mark in the middle of the screen...anyone,any ideea?!?

    Hey ppl,my macbook is not booting and by that i mean u can hear the audio wave when its starting up,the screen goes white and then after a while there's a folder with a question mark in the middle of the screen...anyone,any ideea?!?Regards.

    That folder with the question mark icon means that the MacBook can't find the boot directory. That can either mean it can't find the hard drive or the hard drive data is somehow corrupted.
    Put your install DVD into the drive and reboot. As soon as you hear the boot chime, hold down the "c" key on your keyboard (or the Option key until the Install Disk shows up). That will force your MacBook to boot from the optical drive.
    Once it has finished booting and you are at the Install screen launch Disk Utility from the Utilities menu. Is your Hard Drive in the list on the left?
    If it is then select the First Aid Tab run Repair Disk and if that repairs any problems run it again until the green OK appears and then run Repair Permissions.
    If your hard drive isn’t recognized in Disk Utility then your hard drive is probably dead.

  • Why does my MacBook Pro not boot up with the Snow Leopard Disk?

    I have erased the entire hard drive on a 2011 macbook pro that had snow leopard on it. I was corrupted. I not insert my Snow Leopard Disk and the machine will not boot. I chose target mode to erase the hard drive from my mac book pro with Mt. Lion on it.
    Thank uou for any help,
    Ken

    Target mode?  Is there a second computer involved?  Why not insert the Snow Leopard disc in the computer on which you wish to install and hold down the C key to boot from it?
    If the disc came with a different computer it will not boot another model.  Retail discs also may not boot all model computers, even those that came with the same major version.  For example, some MBPs came with 10.6.6 but a retail disc may only be 10.6.3.

  • Macbook Will Not Boot Up Correctly - PLEASE HELP

    Hello,
    So my MacBook Pro 17" boots up to the login screen where I have two names. One of the login names works fine, but the other will not let me sign in. After I put my password, the desktop background for that name comes up then it freezes and just has the spinning mouse rainbow. I really need to get back in that name as it has all of my programs and projects. How do I fix this?
    Thanks, Joe

    well, it boot up fine now. i ran one boot in safe mode, then restarted and now it boots up fine. i don't really know how safe mode works, but it seemed that one boot fixed the problem!

  • MacBook Pro not booting up after Software Update ('prohibited' symbol)

    Hi there
    I'm having some issues with my (late 2008) MacBook Pro after installing a recent software update: the machine is not booting up, instead displaying the 'prohibited' symbol on the grey bootup screen, thus:
    !http://img828.imageshack.us/img828/7215/photovl.jpg!
    The back story: this morning I ran Software Update and installed the iWork update, the latest security update and the Snow Leopard Graphics Update. This installation apparently went fine, however on the required reboot the computer displayed the above image, and did nothing.
    I booted from the Snow Leopard install DVD, fixed disk permissions and repaired the disc, which Disk Utility claimed was successful; the computer still would not boot.
    I then rebooted from the Snow Leopard DVD and restored from my most recent Time Machine backup (dated a few days ago, before the software update). This, still, did not do the trick.
    As I have never seen this particular issue before, I'm at a loss as to what to try next, partly as I don't really know what the symbol is signifying. Any assistance that can be offered would be very, very useful.
    Cheers in advance!

    Thanks for that, I did go looking for it but couldn't find it.
    Unfortunately, resetting the PRAM and NVRAM didn't work. Will a reinstallation of OS X make a difference, bearing in mind I've already restored from a Time Machine backup? (I don't know if those clone everything or don't include system files).

  • DaisyDisk deleted my password somehow. Macbook will not boot up.

    Okay, so I downloaded DaisyDisk to clean and optimize my Macbook 15" white E2008. I deleted some files and found useless, but then I went to delete some more, and it asked me for admin password, and my admin password did not work. So I logout and log back in and it wouldn't log in with my password. So I restart my computer and now it's not booting up. It's the white apple logo with the spinny icon. I screwed up BIG time! Please don't judge me, it was an honest mistake, but I admit I should've known what I was doing before I did it and now I've learned my lesson the hard way. I have so many irreplaceable pictures of my best friends and lots of songs. If there is a way I can fix this problem or save my files, I would greatly appreciate it. Please and thank you!

    With Command+R -> Re-install OSX, re-installing OSX will leave your files intact. Do not erase and install.
    If that does not work
    1. Option -1 - Build an external bootable drive using - OS X: Installing OS X on an external volume.
    2. Option - 2 - If you have another Mac, you can use Target Disk Mode to access the failed Mac's disk as an external firewire drive. How to use and troubleshoot FireWire target disk mode and OS X Mountain Lion: Transfer files between two computers using target disk mode. You will need a Firewire cable or a TB-to-Firewire cable/adapter if the working Mac is equipped with Thunderbolt. Your 2008 Mac has one FW400 and one FW800 port according to MacBook Pro (Early 2008 and Late 2008) - Technical Specifications or if you have MacBook (Early 2008 and Late 2008) - Technical Specifications it has one FW400 port.

  • Security change hdd. MacBook will not boot.

    Hi all,
    I am in some real need for help.
    Yesterday i changed the security of my macbook(aluminium) because i am at a hotel with wifi.
    (selected in Finder "this computer" pressed command-i, and in information checked the option "secure.")
    At night i shut down my mac without problems. But this morning it does not boot up anymore.
    All i get is the grey screen with Apple logo and spinning progress wheel. It stays in this mode until eternity.
    In verbose mode i checked fsck -f and it said at the end HD is OK. So I recon that there is nothing wrong with
    my hdd in itself. (thought at first that hdd would be chrashed).
    Anybody any ideas?
    Can i undo the security in verbose mode and what is the command line?
    Thanks for all the help. Am in czech republic so not able to go to my usual mac shop.

    Tough without the Install disc, but some things to try...
    Does it boot to Single User Mode, CMD+s keys at bootup, if so try...
    /sbin/fsck -fy
    Repeat until it shows no errors fixed.
    (Space between fsck AND -fy important).
    Resolve startup issues and perform disk maintenance with Disk Utility and fsck...
    http://docs.info.apple.com/article.html?artnum=106214
    Tough without the Tiger Disk problems, but try fsck...
    To use fsck, you must run it from the command line. Unlike using your mouse to open an application to do something, you'll need to type a text command at the prompt (#) to tell fsck what to do. The Terminal application (/Applications/Utilities) and single-user mode are two examples of command-line interfaces in which you can type such commands. To use fsck:
    1. Start up your computer in single-user mode to reach the command line. Hold CMD+s keys down at bootup.
Note: If necessary, perform a forced restart as described in the Emergency Troubleshooting Handbook that came with your computer. On desktop computers, you can do this by pressing the reset/interrupt button (if there is one) or holding down the power button for several seconds. On portable computers, simultaneously press the Command-Control-power keys. If your portable computer doesn't restart with this method, you may need to reset the Power Manager.
    2. At the command-line prompt, type /sbin/fsck -fy
    (SPACE between fsck AND -fy important)
    3. Press Return. fsck will go through five "phases" and then return information about your disk's use and fragmentation. Once it finishes, it'll display this message if no issue is found:

    The volume (nameofvolume) appears to be OK 
If fsck found issues and has altered, repaired, or fixed anything, it will display this message:
*** FILE SYSTEM WAS MODIFIED *** 

Important: If this message appears, repeat the fsck command you typed in step 2 until fsck tells you that your volume appears to be OK (first-pass repairs may uncover additional issues, so this is a normal thing to do).
    4. When fsck reports that your volume is OK, type reboot at the prompt and then press Return.
