Mac OS shows STOP sign at startup

Hey there......well, my mac doesnt seem to work now, whenever i start it up, it stops at the screen where the apple comes up, and after a while a stop symbol comes up. Nothing can be done that i know of. But the thing is, im actually on the same machine right now, only im running windows.....now, i got some questions and hope they can be answered, these are:
Is all my data i had saved, music, photos, all files, doomed, or is there a way to get them back?
What can be done???
Thanks for the help.
Macbook Pro 15 inch, duo core 2 2.33ghz    

Actually it was 8 GB. Well, I couldnt back anything up and just tried booting it from the cd and repairing the disk with Disk Utility and right now im writing from Mac OS X! Im doing backups now on dvds, thanks for the help guys, apreciate it!
Ooooh, there was a small thing i wondered about tho, have anyone heard about an issue when you are burning and the audio goes all screwy if you are listenin to music or whatcin a video, stuttering and all? It happened with me only in Windows so far tho, not on the mac os, but i would think it should go fine burnin cds on windows, is it normal with windows on mbp or?
Anyhow, thanks again for the help!

  • Stop sign at startup

    Hi!
    So, when I start up my Macbook mid-2010, I log in first, and after 30 seconds the stop sign comes up. I am able to log in as a guest user.
    When I load up the install disc of Snow Leopard and choose for Disk Utility, I can see the disk, but it sais it is not mounted? When I click on 'mount', it doesn't respond. see the following screenshot for more info:
    I'm currently running OSX 10.7.3
    2.4 Ghz Intel Core 2 Duo
    8 GB 1067 MHz DDR3
    I currently had some other problems with my mac, see this thread: https://discussions.apple.com/message/17524117#17524117
    Also it might be interesting that I had bootcamped my Mac, but since a couple of days I deleted the partition using the bootcamp utility.
    Hope someone can help me!
    Thanks, Dirk

  • Power Mac G5 Showing Prohibitory Sign on Start Up?

    Earlier this week my Power Mac G5 1.8 ghz dual started to show a prohibitory sign on start up. The hard drive was original to the machine (from 2004) and I wanted to upgrade it to a larger size anyhow, so I put in a new hard drive thinking that might solve the problem and give me an upgrade at the same time.
    After I installed the new hard drive, I formatted it and did a restore from Time Machine of my system. When I restarted, I got the prohibitory sign again. I restarted holding down the option key to see if it found the new drive and it did. So I selected the new drive and it started up from the new drive with my restored system on it with no problem. Then I went to system preferences and made sure the new hard drive was selected as my start up disk. On restart, I got the prohibitory sign again.
    Then the weirdness started. On subsequent restarts, I get the prohibitory sign intermitently whether I'm starting from the hard drive, my Leopard installation DVD, my Disk Warrior boot disk, or my old Panther installation disk. It seems to boot without any problem from the Apple Hardware test CD. I've run the extended apple hardware test and it didn't find any problems. Most of the time, I get a prohibitory sign no matter how I'm trying to boot up, but sometimes it will boot from the Leopard installation disk or the hard drive, but when it does, it freezes after running for a few minutes. I've tried swapping out the memory sticks and it's made no difference.
    Is it possible this is a software problem and not a problem with the motherboard or other hardware? I sure hope so, because I love this machine. Anyone have any suggestions about what I might try next? I've read about the "hair dryer" solution, but if Apple Hardware Test didn't find any probemms with the memory or motherboard, could that still be a solution?
    Thanks for any help or suggestions.

    Thanks, japamac. Yep, I should have said I replaced the old hard drive with the new one. So, it now only has the one, new fresh hard drive. The new drive is a WD Caviar Blue 320gb.
    I set the jumpers on the new drive for 5-6 to slow the new drive down to 1.5. I've also tried resetting the PRAM several times, and tried restarting in safe mode. Every few tries I can get it to boot from the hard drive or a boot DVD/CD (maybe once every 10 tries), but it freezes up after running for about 10 minutes. The only instance this doesn't happen is if I boot with the Apple Hardware Test CD. It didn't freeze up during the 2 hours it took to run the extended test.
    Thanks for trying to help me.

    My Mac OS Lion 10.7 FileVaulted HD does not boot, prohibitory sign, stop sign appears some minutes after boot starts. Disk Utility repair shows four error messages:
    Unable to bootstrap transaction group 2517: inconsistent crosscheck
    No valid commit checkpoint found
    The volume xxxxxxxxxxxxxx(here it shows physical volume number) was found corrupt and can not be repaired.
    Problems were encountered during repair of the partition map
    Error: Storage system verify or repair failed.
    (the same with 2518, 2519 and 2520 transaction group)
    I suppose it is serious bug in Mac OS Lion managing FileVault and wonder what the help could be?

    Most likely culprit is your Lacie drives which are notorious for flaky power supplies which cause just the sort of erratic behaviour that you describe. Have had similar issues myself. Lacie has been good about replacing my power converter-- twice. If you have seven of them, good luck finding the bad one or more. Like I said, the behaviour is erratic. Sometimes it'll work sometimes not. I can't comment on Samsung drives because I've never used them and have never heard anything about them. Same with Softraid. Why not just use Disk Utility. Sounds like you're ready for an external hardware raid. This will be much faster, much more reliable, and may even be cheaper than seven firewire drives. Check out G Tech, and Maxx Digital for starters.
    Best of luck

  • After installing the mountain lion on my Mac at startup a stop sign appears and i cant loguin or do anything.. What should i do?

    After installing the mountain lion on my Mac at startup a stop sign appears and i cant loguin or do anything.. What should i do?

    If you mean the "no entry" sign, a circle with a slash through it, then you need to reinstall Mountain Lion.
    Boot into the Recovery HD by holding down cmd-r at startup tone until gray screen.
    From there, reinstall Mountain Lion.

  • Why Stop sign shows up when I try to install tiger on Lombard

    I knew tiger doesn't support Lombard. However, through the third party software, XPostFacto, I successed to install tiger to my old hard drive (6 GB). I felt the hard drive is too small and then bought a 20 GB hard drive. First, I installed OS 8.6 and found the XpostFacto did't work and then I installed OS 9.0, but when I tried to install tiger to my new hard drive, a stop sign showed up on the screen and my lambard sounds freezed. Can anybody tell me what costs this and what I can do next? I am so appreciated to get your help. Thanks.

    jpl,
    Yes. It is the same Tiger DVD used last time. I thought it is clean and I can see all the files on the DVD.
    Stop sign icon showing repeated:
    1) After last time saw stop sign, I tried Option-Command-Escape, NO Respone.
    2) I Restarted it by pushing Control-Command-Power. PB restarted but the same stop sign icon showed up.
    3) I pressed and released the reset button on the rear of the computer. PB shut down.
    4) Waited over 5 seconds, and then I pressed the Power button to restart the PowerBook computer. In the meantime, I pressed and held the Command-Option-P-R keys until I heards the startup sound for the second time. Computer reboot from HD with Mac OS 9.0. No freezes.
    5) Lauched XPostFacto4 from HD,and made these selection as followings,
    Select Volume: 40 BG HD
    Select Install CD: Mac OS X install DVD
    Restart in: Mac OS X
    NVRAM options:
    boot-device: ode0:7,\BootX.bootinfo
    boot-file: -h -i
    boot-args: -v rd=*idel/@0:3
    auto-boot?: true
    input-device: keyboard
    output-device:screen
    6) Clicked "Install from CD", "Are you sure you want to install Mac OS X now", clicked "Install". PB started to install extensions and items (totally not over 5 seconds), then PB shut down itself, and stop sign icon jumped up again.
    Thanks for your help.

  • Mac won't start, gives me the kernel stop-sign

    Ok, this is my big big problem..
    One day, i was just doing nothing on my dear computer, starting up firefox or something, then suddenly everything stopped. I couldn't do anything. I forced-restarted the computer with the boot-button. When im trying to start it over again, i get to the white startup-screen with the apple-icon in the middle, with the loading-circle underneath it. After a while, the apple-icon changes to a grey stop sign (picture of it further down).
    So, what have i tried?
    Trying to boot with CD, says i can't install Mac OS, but i can go into the Disk utility, Verify Disk / Repair Disk:
    Verifying volume "Macintosh HD"
    Checking Journaled HFS Plus volume.
    Invalid node structure

    I have time machine on my external hdd, but when pressing the time machine-button after trying to start with CD, nothing happens.
    When starting the computer holding down SHIFT-button, i get a white screen with black text, and a square saying 'You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again." The black text in the foreground says:

    There is this Apple Knowledge Base article, which describes your issue:
    http://support.apple.com/kb/TS1892?viewlocale=en_US
    However, it sounds as though you have tried most of what's there. If it won't allow you to reinstall the OS, then there is definitely something amiss with your hard drive.
    Sometimes a third-party disk utility (such as Drive Genius) can repair a drive when Apple's own Disk Utility cannot.
    Good luck with it.

  • Can't boot on my external hard drive on another Mac (stop sign)

    Hi,
    My system is placed on an external SSD connected to my iMac.
    I've just bought a brand new Mac Mini and I wish to boot it using my SSD.
    When I pick it up in the startup alternatives list (maintening the "Alt" key pressed during the boot), I just get a gray screen with a stop sign at the middle. Then the Mini shuts down.
    Isn't it possible at all to use the same boot disk on my iMac and on my Mini ? (I don't intend to use it constantly on both, I was just hoping to migrate flawlessly using the same System disk).
    Note :
    - when I plug it back to my iMac, the iMac boots up normally
    - if I boot my Mac Mini using the internal hard drive, I can access to all the content of my SSD. I performed a full disk check on it using the Disk Utility and everything's fine. I just can't boot with it.
    - of course, both of the systems (iMac/SSD and Mac Mini internal HDD) are up-to-date (10.8.2)
    Thanks for your help.

    Most likely, the new mini can't boot with the iMac's components. See Don't install a version of Mac OS X earlier than what came with your Mac and Computer-specific Mac OS X releases for details.

  • Stop sign on first boot (mac mini 2013)

    Hello, I've just turned on for the first time my Mac mini, and it seems something is wrong... apple sign appears for 30 secongs, and then stop sign shows and this is the end of boot...
    help people....

    The OS X copy is damaged. If I were you, I would simply return it. You have 14 days since the purchase date to return the Mac and get another one for free, so I recommend you to do this.
    If you want to try to solve the problem, hold Command, Option (Alt) and R keys while your Mac is starting to start up in Internet Recovery, and reinstall OS X

  • "Stop Sign" when starting the mac after reinstallation...

    Hello,
    I had a problem with my mac mini OS X Lion, the  problem was that some symbols started to change places and dissapear. so i called the apple support and they tryed to help me for 1.5h on phone without success, the last thing they told me to do was to erase the disk and totaly reinstall the OS, so i did.
    it was downloading for about 5h and when i checked it the day after it was a "stop sign" on the screen so i waited for another day and the sign was still there,so i hold in the start buttom to force it to turn of and started again, the apple sign showed up for about 30sec - 1 min and then the stop sign appeared again....
    i also tryed to start it with holding in the mac buttom and R, and also D when clicking on the start buttom without success..
    did anyone else experience this ****?
    If so please give me some tips so my lovely mac can come back to life.
    Kind Regards
    Ompaa

    OK, sounds like things aren't as bad as I feared. Could be a problem with your internet connection. In any case, start again.
    Follow this guideline EXACTLY (http://support.apple.com/kb/HT4718):
    The short version:
    Restart your Mac and hold down the Command key and the R key (Command-R), and keep holding them until the Apple icon appears.
    After the Recovery HD has finished starting up, you should see a desktop with a Mac OS X menu bar and a "Mac OS X Utilities" application window.
    In order to reinstall OS X Lion, you will need to be connected to an Ethernet or Wi-Fi network. The Wi-Fi menu item is in the upper-right corner of the screen. Click the icon to display all available Wi-Fi networks. Click your preferred network name and, if needed, enter a username and/or password for your wifi.
