There's your problem then. You can't use a disc from another model of Mac - they're specific to each model.
You'll need to buy the Snow Leopard retail disc from the online Apple Store. It's the only one that will work.

  • Wiped my entire macbook drive and now snow leopard won't install over snow leopard server, HELP!

    I ordered, what I thought, was Snow Leopard a while ago because I was running Leopard and I wanted to get the app store so I could move onto Lion and then Mountain Lion. I ordered the disc over the phone and the woman sent me the Snow Leopard Server instead of just Snow Leopard, I didn't think much about it so I clean installed it and ran it on my unibody macbook for a while. I didn't see much use for the disc anymore seeing that everything was downloadable at this point, so I sold the disc on Ebay and carried on. The server edition started to slow my computer down due to all of its excess applications and what not, and I read online that Lion and Mountain Lion are also very slow on the old unibody Macbooks so I ordered a regular Snow Leopard disc, now available online, and tried to install it. My computer said Snow Leopard cannot be installed over Snow Leopard server so I went to disc utitlity and wiped my entire drive while the OS X Snow Leopard disc was running and trying to install. I went back to the install window and it still said OS X Snow leopard cannot be installed over Snow Leopard Server so I shut down my computer and tried to turn it back on and I all I got was a blinking folder with a question mark in it, what do I do????????
    P.S. All of my content is backed up on an external harddrive so I am all good with that.

    Drive Preparation
    1. Boot from your OS X Installer Disc. 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.
    2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  SMART info will not be reported  on external drives. Otherwise, click on the Partition tab in the DU main window.
    3. 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.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    7. After formatting has finished quit DU and return to the installer. Complete the Snow Leopard installation.

  • Snow Leopard Won't Install

    I get maybe 15 minutes into the install, and my MacBook restarts; Snow Leopard is not installed. I didn't notice any error message before this happened.
    This happened 3 times.

    Greetings,
    It takes around 45 minutes for the install to complete. After the first 15 minutes, or so, it will reboot, and then continue the installation. Hopefully you didn't interrupt it at a critical moment.
    If you did and it won't boot at all, you may have to insert the DVD in the drive, start it up, and hold the "C" key down until you see the Apple, and little spinning graphic.
    After it boots in to the DVD, then install.
    Cheers,
    M.

  • Snow Leopard Won't Install Even With Replacement Disk

    I got my original Snow Leopard, that I bought at Apple, a week ago. I went through the whole installation process, and about halfway through, it restart and ejected the disc. After that the disc wouldn't read. So I got support from Apple and they sent me out a replacement disk that I got today. I start installing and the EXACT same thing happens again. Any ideas on what the problem is? And yes, the disc drive is working fine.

    Make sure that at least 1 GB of memory is recognized in System Profiler with status "OK" -- it is possible that some of your installed memory is defective or not properly seated. Since Snow Leopard requires at least 1 GB, your MacBook won't start up from the DVD if can only use less than this amount.
    Also consider running the Apple Hardware Test and/or Kelley Computing's Rember on your MacBook, especially if you have replaced any of its original memory with third party parts.
    Because Snow Leopard is more demanding of memory performance than Leopard & has a higher minimum requirement for memory size as well, sometimes slightly out-of-spec memory modules will work fine with the earlier OS version but not with the later one.

  • Snow Leopard won't install because drive is not Mac OS Extended (Journaled)

    I cannot install Snow Leopard (from regular Leopard) on my other 21" Intel iMac (not this one) because the hard drive is apparently only Mac OS Extended and NOT Mac OS Extended "(Journaled)".
    Is there a fix for this? Everything else on the computer is working fine (and has been for a few years)
    I'm not sure how it got that way but a few years ago I used Disk Warrior to correct some problems - maybe I re-imaged the hard rive using Disk Warrior into the wrong format?
    Disk Utility confirms that the hard rive is indeed Mac OS Extended (what is the difference with "Journaled" anyway?).
    I'm loathe to erase the disk, reformat, and use Time Machine to reload the data (what if the back-up drive is incompatible with the reformatted Mac OS Extended Journaled)? Maybe I can use Disk Warrior to re-image the disk to Mac OS Extended (Journaled)?
    Please advise best way to handle this situation.
    Thanks!

    If you are certain the only problem is that the startup volume is not Mac OS Extended "(Journaled)" you may be able to fix this with Disk Utility: Select the volume in the list, then press command + j or select "Enable Journaling" from Disk Utility's File menu.
    However, the reason the Snow Leopard installer may not allow the install is because the drive must be formatted with the *GUID Partition Table* Partition Map Scheme. If you, you will have to reformat the drive. To determine the Partition Map Scheme, select the drive (not the volume name indented below it) in Disk Utility & look at the last line of info in the window.

  • I have a Mac Pro 8 Core and Snow Leopard won't install from the DVD.

    Any idea why?

    Either your machine doesn't meet the [Snow Leopard system requirements|http://www.apple.com/macosx/specs.html] - which I can't imagine would be the case for that machine, though I don't know that for sure - or you're using the wrong disk. Note that the gray disks that shipped with one machine will not work on a different one, unless they are exactly identical models. Or, I suppose, you've got a bad disk or hardware problem.

  • 2010 Macbook Pro / OSX Snow Leopard /  Won't Install Mavericks

    A friend of mine has tried repeatedly to update his laptop to OS Mavericks, but when his computer restarts it gets stuck at that step and will not finish.  What must be done to make the installation complete itself?

    Have your friend try this:
    Repair the Hard Drive and Permissions - Mavericks, Lion/Mountain Lion
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.
    And, be sure there is at least 20 GBs of free space on the hard drive for the installation.

    If you have your old system backed up then erase the drive and restore your backup. If you don't have a backup then backup your entire Home folder. Erase the drive and install Snow Leopard after which you can restore your Home folder from the backup.
    Clean Install of Snow Leopard
    Be sure to make a backup first because the following procedure will erase
    the drive and everything on it.
         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.
    Or you can:
    Try these in order testing your system after each to see if it's back to normal:
    1. a. Resetting your Mac's PRAM and NVRAM
        b. Intel-based Macs: Resetting the System Management Controller (SMC)
    2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
         Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
         COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the
         computer and after the chime press and hold down the OPTION key until the boot manager
         screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
         Reinstall the 10.9.3 update: OS X Mavericks 10.9.3 Update (Combo).
    4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    Reinstall the 10.9.3 update: OS X Mavericks 10.9.3 Update (Combo).

  • My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard (via my MacBookPro), either from the HD or DVD drive.  Can't get it to run Hardware Test.  Disk Utility says disk OK - files are there. What can I do?

    My 2006 iMac running Snow Leopard won't boot even after erasing and re-installing Snow Leopard.   I erased and re-installed by putting the iMac in Target Disk mode and usin my MacBookPro as the host.  But after numerous attempts I still can't get it to boot either from the HD or DVD drive. I just get the white screen after the wheel stops spinning.  I can't get it to run Hardware Test - just get the white screen.  If I use Disk Utility via my MBP it says the disk appears OK. All the Snow Leopad files appear to have been installed. What can I do?

    Perhaps you installed the wrong version OS X onto the iMac, you can't use the disk from another Mac.
    clean the disk.
    If it's not working then use this method to create a bootable 10.6 USB from the iMac machine specific 10.6 disk or the 10.6.3 retail disk on your other Mac, use it to boot the iMac with.

    How to erase and install Snow Leopard 10.6

  • Hello, I have a 2009 iMac, and my harddrive has failed several times now, and now I need to re-install snow leopard but my install DVD is damaged and I have bought a new snow leopard disc. However my iMac will not read the disc at all ?

    Hello, I have a 2009 iMac, and my harddrive has failed several times now.
    I tired to reinstall snow leopard with the install DVD that came with my iMac. However the disc is damaged so I bought a new Snow Leopard but my iMac wont read the new disc, it just stays in the apple logo screen, I have tired safe boot, holding down the "C" key on startup and tried using disc utility but getting nowhere.
    Please help. Thanks.

    Might be related, if your hard drive is a 1TB drive,it could be a Seagate drive.
    The drives are known to fail and your iMac maybe covered for free replacement under the Apple's Seagate hard drive replacement program until April 12 of this year.
    I Believe the 2009 models are covered under this replacement warranty.
    You can find out if you are eligible here.

  • IMac 27' (year 2010 - Snow Leopard) won't boot - white screen only

    Hi,
    my 2010 iMac 27in running Snow Leopard won't start - when I switch it on, I can hear the chime, the screen goes white and gets stuck at this (no Apple logo, no question mark, no mouse pointer). I have waited for minutes but it's definitely stuck.
    When there is a DVD in (tried both OSX Instal and Apps Instal), I can hear the drive reading for a few seconds, then it goes silent.
    I have found a few similar topics in this and other forums - the issue was solved or helped by entering one of the special boot modes via keyboard shortcuts upon startup. In my case though, none of these shortcuts work - with the sole exception of Cmd+Alt+P+R to reset the NVRAM. What I tried was: C, D, Alt, Eject, N, T, Shift, Cmd-V, Cmd-S ...none of them has any effect.
    I learned there are some issues with a wireless keyboard when using these shortcuts, so I got a USB one to rule that out - but it didn't help.
    In the beginning, I heard "clicking" noise I am not used to hearing - so I suspect a HDD failure but it would surprise me the machine would not indicate that in some better way than a blank white screen. The clicking then went away - could be after I did the NVRAM reset - not sure.
    I also performed an SMC reset by unplugging the power cord for a while - no effect.
    As per one recommendation, I tried NVRAM reset a few times in a row. Didn't help but, interestingly, I found that after 3 such resets, holding D will eject the DVD (without the 3 resets, "D" won't do it). Prior to that I had no way of getting the DVD out.
    The computer was running fine before I switched it off for the night on the previous day. There was no system update, no change I am aware of.
    The only thing beyond default is extra RAM but that has been there for months now without problems (and just to be super sure, I removed the modules but no effect).
    At this point I have run out of ideas - any suggestions are very welcome.

    Some things you can try.

  • If you lost your install CD's for an iMac7,1. Can you use Snow Leopard to reboot/install?

    If you lost your install CD's for an iMac7,1. Can you use Snow Leopard to reboot/install?

    Best answer; see AnaMusic above.
    Will SL do? Yes, provided you use the SL retail disc. A grey disc from another Mac will not work.
    A few considerations -
    Be warned that printer drivers, and scanner drivers in particular will almost certainly need updating for SL. That could be a problem if the printer or scanner is more than a couple of years old.
    Many third party applications (and some Apple ones) may need updates for SL (Adobe particularly), so check with the vendors for compatability before you upgrade.
    You'll need Rosetta to run PPC apps like Appleworks and many MS Office or Adobe versions. Ensure you select it from the 'optional installations' when installing SL.
    Note also that any bundled applications that came with your Tiger original discs (iLife in particular) are not included on retail OS versions.
