Can't boot from Mac OSX CD.

Hi, i wanted to do a fresh install of snow leopard on my MBP, but when i try to boot from the snow leopard disk, it just hangs at a white screen with a grey apple logo on it. Ive tried install it from my desktop, it finished but absolutely nothing happened. Ive also tried booting while pressing option, and while pressing c.
I also want to use disk utility from the installation disk to repair my Macintosh HD. But i cant get into the cd..
oh yeah and while i tried to install it from my desktop, there was this button on the left bottom corner called Utilities. I pressed it thinking that disk utility was there and it told me to boot into the disk. I pressed restart and the same thing happened. it just hangs at the white screen with the grey apple logo. nothing else. and i also hear the disk stop spinning.
any ideas???

Maybe you killed your boot drive.
Normally you should of course be able to boot from SL DVD and instead of INSTALL go to menu bar and UTILITIES and select DISK UTILITY.
ZAP the PRAM will result in the "?" because the boot volume setting is no longer present. You can reset that also from SL DVD Utility / Startup Disk
My methods:
Clone and have a bootable backup first, DU Restore; or SuperDuper
Run utilities from there, like Disk Warrior
Even though you are suppose to be able to install from desktop, SL also needs to "prepare disk" (update partition table) and it is safer and really really adviseable to do repair from the DVD, as with any upgrade have a couple backups in place first.

  • Can I upgrade from mac OSX 10.6.8 to 10.8?

    Can I upgrade from mac OSX 10.6.8 to 10.8?

    Same list as stedman1, but uses model numbers which is slightly more accurate.
    Check that your computer is compatible with Mountain Lion.
    To check the model number hold down the option/alt key, go to the Apple menu and select System Information.
    iMac (Mid 2007 or newer) model number 7,1 or higher
    MacBook (Late 2008 Aluminum, or Early 2009 or newer) model number 5,1 or higher
    MacBook Pro (Mid/Late 2007 or newer) model number 3,1 or higher
    MacBook Air (Late 2008 or newer) model number 2,1 or higher
    Mac mini (Early 2009 or newer) model number 3,1 or higher
    Mac Pro (Early 2008 or newer) model number 3,1 or higher
    Xserve (Early 2009) model number 3,1 or higher
    Your Mac needs:
    OS X v10.6.8 or OS X Lion already installed
    2 GB or more of memory (More is better)
    8 GB or more of available space
    Check to make sure your applications are compatible.         Application Compatibility
    If you have applications that you want to use that aren’t compatible, you can retain Snow Leopard and create a new partition to install Mountain Lion on or you can run Snow Leopard  server in a virtual mode.
    If your computer isn't compatible, you might be able to upgrade to Lion.        Computer Compatibility - Lion
    If you can/do upgrade, I recommend you make a copy of the installer and move it out of your Applications folder. The installer self-destructs. The copy will keep you from having to download the installer again.

  • Can't boot to Mac osx, Error -2100F

    Hi there,
    I got a Macbook Pro Retina Late 2012, and I made a dual boot to Windows 7 today.
    The problem is when I try to boot to Mac osx it automaticly start up as Windows 7.
    I tried to use the Command key to get the Mac osx running and the only boot that I see is Windows 7.
    After that i tried using Command + R to recover it and it gave me an error -2100F.
    I also tried to use Boot Camp to Boot to Mac but that also goes straight to Windows.
    My guess is that I deleted the wrong partition when I installed Windows 7 and that i am unable to boot to Mac osx now.
    Can anyone help me fix the problem?
    Thanks in Advance

    Use your backup(s). Erase and restore.
    Also XP is not being actively supported.
    With OS X upgrades you always need to check and make sure you have the latest, like Parallels 7, or there is VirtualBox 4.x
    Sounds like you simply had a corrupt hard drive.
    Lion 10.7 will only support Windows 7 except in a VM.

  • I can't boot from mac installation disc even while holding 'c' button

    I can't boot from installation disc even while holding 'c' or 'option' button. It remains at the grey screen. How do i overcome this?

    Can you boot normally and use System Preferences> Startup Disk to select the CD as the boot volume?

  • Booting from Mac OSX Instead of Windows

    Hey, I'm wondering if anyone could help me with a very minor but irritating problem I've been having. I installed "Bootcamp" and ran the program to partition my drive and run windows. It worked perfectly, but the only problem is now my iMac boots directly from Windows as soon as I restart or startup my computer. I would much rather it boot straight to OSX so that I could avoid pressing the "option" key continually on startup and restart.
    Thanks

    In OS X, go to System Preferences > Startup Disk and select Mac OS X.
    You can do the same thing in Windows by going to Control Panel > Startup Disk.

  • Can not boot from Mac OS X Install Disc 1, G5, Snow Leopard

    I have version 10.6.8 installed. Compter is a 2 x 2.66 GHz Dual-Core Intel Xeon. 6GB memory
    I want to run Disk Utility and startup from the install CD that came with the computer (the grey one, disc 1, or even the retail disc Mac OS X Snow leopard, the whit one) but I CAN NOT DO IT. So frustrating.
    I restart, hold down the "C" key, before the chime, after the chime, every which way, and my Mac always acts as if I am simply restarting, goes right to the login screen everytime. I tried holding down OPTION on restart to choose which to startup from, but only saw the hard drive as an option. I open System Preferences, Startup Disk and the install CD does not even show up as a choice to start from, yet the install CD shows up in the finder.
    What am I doing wrong?
    Thanks

    OK.
    According to  the knowledge base that model should have shipped with Tiger, 10.4.7.
    Going to need some thought here, though. I was going to suggest a possible problem with the optical drive, but you say the DVD mounts on the desktop as a normal DVD would?
    Nevertheless, do you have access to another Mac or an external HD with a bootable OS X on it (later than the Tiger version your Mac Pro shipped with)?
    If so, try booting from the external, or from the other Mac using Firewire Target Disk mode, and using DU from one of those sources to repair the MP's internal HD, then try the disc(s) again.

  • Cannot access boot from Mac OSX install Disc-frozen cursor

    Twice a month I do some housekeeping and clean up my Mac--run scripts, verify preferences, repair permissions, etc. Quarterly I boot from the installation disc to renew any start up info that may have become corrupted.
    My IMACG5 won't allow me to do this now. I put the disc in, and shut down the machine. I start it up again while holding down the C key but when it is finished booting from the disc my mouse cursor is frozen on the screen and I cannot acess anything. I have a battery operated mouse and I always check to make sure there is sufficient battery life.
    Does anyone have any suggestions as to what is up and how I resolve this issue? At this point I won't be able to wipe my hard drive and re-boot everything fresh from my installaion discs because the cursor is frozen.
    IMACG5   Mac OS X (10.3.9)   wireless keyboard and mouse

    Hello jaqueline & Welcome to Apple discussions
    I put the disc in, and shut down the machine.I start it up again while holding down the C key but when it is finished booting from the disc my mouse cursor is frozen on the screen and I cannot acess anything.
    I hope you mean Restart and not Shut Down.
    Insert CD, under Apple drop down menu -> restart after/ at the chime hold the c key dowm till the gear/ wheel stops spinning .

  • Can not boot from OSX disc

    I recently partitioned my internal drive with an 80 gig partition to run Ubuntu , removed Ubuntu and now can not resize hd to recover the 80 gig that I used , there was a program with this Ubuntu install called rEFIt that was installed for the dual boot , My problem is that Itunes keeps crashing and I have spent somewhere around 8 hours trying to fix this issue and in the process I discovered that I now can not boot from the osx disc but I can boot from the Ubuntu disc , what can I do to correct this issue or is there anything that I can do to correct this and recover the 80 gig that I used ?

    The only solution was to erase hd and restore from time machine backup......
    According to everything that I have seen , read and tried when you partition the mac hd the way that mac is designed it will lock the hd thus preventing any access even using the startup disc to repair. As far as restoring everything after the erase and reinstall of the OSX that was easy and painless. FOR ANYONE WHO DOES NOT BACKUP THEIR DATA THIS IS WHY YOU SHOULD!!!!
    Once OSX is reinstalled the migration assistant will ask if you want to restore from a backup , if you have time machine or any other sort of backup simply choose the one you wish to restore from and continue , must admit I was a bit hesitant at first , I must say that everything restored with the exception of some settings that I have had to restore but they were not major settings  , after the backup is restored simply run update check and reinstall all updates , may need to do this a couple of times.
    Depending on the amount of data you have will determine the length of time for restore (500 gigs about 6 hrs.) but it will restore user account settings , connection settings  and network settings.
    Hope this will help if anyone has experienced the same problem.

  • Can't boot from OSX cd - Kernel Panic or bad CPU?

    Greetings, All! I've looked at all the articles related to this that I can find, here and on other sites, but have not been able to solve the problem. Here's a list to briefly describe my issue:
    -Got Prohibitory sign on my MDD Dual 867 when I tried booting into OS X (10.3).
    -Tried all the resets (PRAM, PMU), re-seated RAM, took out RAM, etc.
    -Trashed OS, and tried to re-install, but Mac won't boot from DVD (10.3) or CD (10.2) - just get the spinning wheel and finally Prohibitory sign...
    -Ran Hardware test to loop for about 17 hours; nothing, all fine.
    Then I just recently noticed that when I run Digital Performer 3 (OS9), it usually shows 2 usage indicators for CPU performance (1 for each processor) but now only shows one. So, I'm thinking a processor may have died, or become unseated, or something. But I read somewhere, on one of the forums, that it isn't likely for one of a pair of processors to go, or if it did, the other wouldn't be able to function solo. But if that weren't the case, and the Mac can run on 1 processor, why would that keep the Mac from booting from the OSX disk?
    The Mac still runs fine in OS9, though it does seem to be a little slower when I do processor-intensive operations in DP, and sometimes hangs on startup, and seems to have some "sleep" issues (won't wake back up sometimes...). I don't know of any way to check if both processors are functioning in OS9. Does anyone know of a utility that will do that? Or if there's one in the OS (The Profiler only shows processor speed)? And would that cause the Kernel Panic and keep the Mac from booting in OSX? It's very frustrating. I appreciate any help or tips anyone may have to offer. Peace, Gelon

    Hey Guys!
    I think I know the "why", but not the solution...
    I have a PowerMac G4 400Mhz Dual Processor, and some day I had the same troubles. No boot on OS X, but I can in OS9. Checking the Open Firmware commands, I saw one of the processor marked as "dead". So, (dont't ask how) I removed one processor from the logic board. Now I got the same "Processor dead", I can boot on OS9, (with an alert for the processor) but is stable. No boot in OS X.
    So, what I suposse (having the same reports in PC computers trying to run OS X) is that the OS X checks for the compliance of the System for running. When a processor fails, the OS X can not recognize the system as valid (as in some PC computers happens) and can not boot. I also suposse if we can get a "patched" OS X for PowerPC or patch the firmware in any way, we can work with just one processor. Or, buying a new processor for the Mac.
    Pls. send me your comments.

  • Can't boot from OSX Install disc.

    Hello,
    I am trying to restore my iMac from a Time MAchine backup and to do that I remembered that I had to boot off of the OSX install disk and choose Disk Utility. I thought that restoring from timeMAchine would be the hard and long part, but I am having trouble booting off of the OSX disc.
    1.) I popped it into my iMac and it mounts and loads. Its runs fine so I know there is nothing wrong with the disc.
    2.) I restarted my iMac and held C.
    3.) The grey screen appeard and then the Apple logo and then the spinning icon underneath it. But it gets stuck there and doesn't boot off of the disk.
    4.) I shutdown the machine by holding the power-button and when it restarted I held D. It ran the hardware test fine and I passed the hardware test.
    5.) I shut it down again, same way in four, and held option. This time I chose to boot form the Mac OS X Install DVD. It again got stuck at the Grey screen with the Apple logo and the spinning icon.
    Does anyone know how to or can help me get my iMac to boot from the OSX install disc or how I can use Disc Utility to restore my iMac from TimeMachine?
    Thanks in Advance & Best Regards,
    theirf.

    Sorry, OE = Original Equipment - the grey discs that came with your Mac.
    SL = Snow Leopard - Mac OS X 10.6.x.
    theirf wrote:
    What do OE and SL mean?
    I think i understand though. You mean that any disc with a higher version of something will still work on a machine with a lower version of that thing right?
    Not any disc. The only grey ones that will work are those that came with that Mac.
    Any retail disc of a later OS version will work, and in most cases it would boot from an external HD with a later OS installed.
    However, as Snow Leopard only came on two retail versions, 10.6.0 and 10.6.3, the choice is a bit limited.
    The current retail version is available here.

    If you have a Mid 2010 model: Computers that can be upgraded to use OS X Internet Recovery. If later then see below:
    Install Mavericks, Lion/Mountain Lion Using Internet Recovery
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Internet Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
    Partition and Format the hard drive:
    Select Disk Utility from the main menu and click on the Continue button.
    After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    If you have an earlier model:
    Clean Install of Snow Leopard
         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
             with your computer.  Insert the disc into the optical drive and restart the computer.
             After the chime press and hold down the  "C" key.  Release the key when you see
             a small spinning gear appear below the dark gray Apple logo.
         2. After the installer loads select your language and click on the Continue
             button. When the menu bar appears select Disk Utility from the Utilities menu.
             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
             size.)  Click on the Partition tab in the DU main window.  Set the number of
             partitions to one (1) from the Partitions drop down menu, click on Options button
             and select GUID, click on OK, then set the format type to MacOS Extended
             (Journaled, if supported), then click on the Apply button.
         3. When the formatting has completed quit DU and return to the installer.  Proceed
             with the OS X installation and follow the directions included with the installer.
         4. When the installation has completed your computer will Restart into the Setup
             Assistant. Be sure you configure your initial admin account with the exact same
             username and password that you used on your old drive. After you finish Setup
             Assistant will complete the installation after which you will be running a fresh
             install of OS X.  You can now begin the update process by opening Software
             Update and installing all recommended updates to bring your installation current.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.

    I am just setting up a 2013 Mac Pro with a 4TB USB 3.0 external drive. I have cloned my boot disc over to it but have problems being able to boot from the USB drive.
    It shows up in the startup disc in system preferences, but when selected as the boot disc and restarted it just boots from the internal SSD. Also have checked booting and holding the ALT key to see what happens but I am just shown the SSD and Recovery disc as options to boot from.
    So it appears I can not boot from a USB disc on my new Mac Pro, is there a solution to this problem?

    Can the Mac mini October 2012 boot from Mac OS X 10.6.8 (Snow Leopard)?
    No. Your best option by far is to find updates or replacements for that long-obsolete software. In the long run, you'll have no other choice. As a last resort, you could do this:
    Installing Snow Leopard (and Rosetta) into Parallels
    The instructions are slightly out of date. That's not a recommendation and I haven't tried it myself.
