IMac won't boot from OS install disc

Hello. I'm using a refurbished 2010 - 2011 iMac running Snow Leopard, which did not come with the original install disc. Just purchased from Apple, an OS (Snow Leopard) Install Disc specific for my model iMac but my machine will not boot from it.
I've tried booting from the disc holding down the "C" key and it tries to start up but all I see is the grey Apple logo, no spinning gear and it just hangs there. I've also tried holding down the Option key and selecting the Install disc from the start-up choices that display but the same thing happens. Any ideas, anyone?

Did you call Apple and ask for replacement disks (giving them your serial number)?
If not, and if you purchased the retail version at the Apple store online, then you may have a version that is older than what yours came with. And, macs cannot boot from an OS older than what they came with. I believe the latest retail version is 10.6.3 and yours might have had 10.6.4 or higher. You might want to check on your model to get the exact OS version; you may need to call Apple and request replacement disks.

  • IMac won't boot from OS X install disc!

    I'm needing to do some internal hard drive repairs but the system won't boot from the install disc! I've restarted it tons of times while holding down "C" and it just bypasses it and boots right into OS X. It restarts as normal with the chime (I am holding down "C") then the Apple logo comes up, then the spinning circle thing, but it just goes right into OS X. Help!

    Let's be sure you are doing it properly.
    First, you must use the OS X Installer Disc One that came with your computer. Carefully check both surfaces for scratches, dirt, fingerprints and if so clean it carefully with a very soft cleaning cloth that won't scratch the disc.
    Second, 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 the spinning gear appears below the dark gray Apple logo.

  • IMac won't boot from install disc

    My iMac has been running a little slow the past two days and so I ran Disk Utility. DU reported that I had the incorrect number of thread records and an invalid volume count. It instructed me to repair the disk by booting from the install disc. The problem is that when I try to boot from the install disc (after I choose the disc from the options), I just get a gray screen with the apple logo on it. Nothing else happens, no disc activity, nothing.
    Anyone have any ideas as to how to get my iMac to boot from the disc and, ultimately, to get Repair Disc running from DU?
    Thanks,
    Rich

    It should only take a minute or so at most to boot from the DVD.
    If your sure you have the correct Install Disk for that iMac, I'd start over. Then if it still doesn't work then perhaps a trip to your Local Apple Service Provider with the Disk or Disk and iMac is in order.

    Alternately using the correct Disk as per the following article, see if you can run the Apple Hardware Test? > http://support.apple.com/kb/HT1509

  • 27" iMac won't boot from anything BUT the main drive

    Hi all,
    My lovely 27" iMac is in perfect working condition, but I thought I'd try to install a OS on a large SD card to see if I would gain any speed.
    In the process of doing that (cause I never got that far) I discover that the iMac won't boot from the original install DVD. It simply spits out the DVD when I try to insert into the drive. I'v managed to make an image of the DVD (in a different mac) onto the SD card in order to try an boot from that. No luck. I've tried to insert a original install DVD from my Mac Pro into the iMac, which it reads fine and well, and when I tap the restart button it restarts, but stop with a white screen doing boot up.
    If I try to hold down the option key during startup, the iMac WILL let me choose which OS to boot from, but if I choose anything else than the OS already installed it freezes.
    I've even tried to boot my Mac Pro from the iMac install DVD - no problems.
    I've even run a hardware test on the iMac - no problems.
    I am running out of options fast! Please help a devoted Mac-friend.
    Take care.
    Peter

    I WAS using the DVD that came with the machine, but I fear Apple may have sent me the wrong one?
    In trying to solve the issues I'd tried other OS disc's (A Mac Pro install DVD and a OS X Leopard DVD) - but none of them would even boot, nor install of my iMac. I always end up with a white screen during boot up.
    As I described, the original iMac install DVD would indeed boot my Mac Pro, do the disc seems ok?

  • IMac won't boot from any HDD or install disc

    Hi everybody.
    This morning my iMac just didn't wanna boot up, it powers on and the start sound plays but nothing more, all white screen.
    Tried holding OPT at start, my mouse cursor becomes visible and active but none of my startup drives show. Also tried booting from both SL and leopard install DVD, it reads the disc for a minute or two then spits it out, nothing on the screen, all white.
    Tried resetting PRAM, holding down CMDOPT+PR, it reboots but same thing after that.
    My internal HDD crashed recently so I've been booting from my external drive which has SL installed. This has worked fine unitl now, last night I shut the machine down it did take an extra two minutes to power off which was out of the ordinary.
    All help appreciated which can avoid me from sending it in for repair.

    Thanks for the reply.
    Since my internal drive had been failing I guessed it had to be the culprit and right I was. After I swapped the HDD (plus swiped the interior clean) my iMac was like new again plus I didn't have to send it away.
    But what I can't quite understand is why a bad internal drive which was not in use would hinder the mac from booting from the install DVD all of a sudden.

  • G4 won't boot from any Linux disc I put in it and c key no longer boots cd

    I have a G4 Powermac (sawtooth, DVD drive, 512 MB RAM, 30 GB HDD) which has started refusing to boot from any Ububtu discs I have all of a sudden.
    I'll be more specific. I've previously been able to boot from Ubuntu 6 cds (originals from shipit, not burnt) as well as Ubuntu 7 (burnt disc). I haven't made any changes to the system that should stop it booting from them. Currently installed on the hard disc is System 9 and Puma. It is still booting ok from my System 9, Puma, Panther and Tiger discs; but when trying to boot from my ubuntu discs (I've tried all of them to eliminate the possibility of a stuffed disc) the screen goes black for a second as if it is starting to boot, but then it kicks me to the flashing folder screen you get when it can't find a startup disc. Oddly enough the background colour of this screen isn't grey like usual. It's orange. I've never seen that before. If I leave it sitting at this screen after about 30 seconds or so it starts up from the hard disc on its own.
    Another odd thing: the c key no longer forces the machine to boot from the cd when held on power up. This is extremely odd, as holding down option brings up the startup disc selector, and cmdopt+shiftdel also works. I've tried everything I can think of. Used a different keyboard, reset the NVRAM (by cmdopt+pr and my manually going into open firmware and doing a "reset-nvram" and "reset-all"). I've tried the PMU reset switch on the logic board. I've tried using different drives. In all cases it still refuses to boot from cd when holding c.
    I don't think that the mac refusing to boot while holding the c key is coincidental. I believe that whatever the issue is that's causing this issue is what is also causing the mac from not booting any Ubuntu discs. It's a very strange problem and upon searching around, it seems this doesn't seem to have happened to anyone else before. Any advice will be greatly appreciated. Thanks.

    Hi, yoshi -
    I just have to be rush to get the cd in the drive and then to hit cmdshift+optdelete before it's too late...
    You should also be able to use Startup Manager to choose the CD as the boot volume -
    Article #HT1310 - Startup Manager: How to Select a Startup Volume
    A feature not discussed in that article -
    Once Startup Manager has loaded, if the CD is not in the drive you can press Command-. (Command-periodkey) to open the drive - this should work even if another disk is already in the drive. Insert the disk you want to use, close the tray, wait a few seconds for the disk to spin up and get recognized, then click the circular arrow icon on the left - this forces a rescan of the available drives, which should result in an icon of the new disk appearing in the array. Click it to select it and then click the straight arrow icon on the right (or press Return).

  • IMac won't boot from Firewire?

    Hey gang-
    I wanted to post this to save anyone else pulling out their hair if they have a Mac that won't boot from a Western Digital (WD) external Firewire drive.  I recently purchased a Western Digital My Book Studio 2 TB FireWire 800 External Hard Drive.
    I bought this drive intending to partition it into two 1TB partitions- one for a bootable backup and one for a Time Machine backup. I do my bootable backups with the application SuperDuper, which is outstanding for this purpose. I have used it to create bootable backups on 3 different Maxtor external Firewire drives, and they have all flawlessly booted all my Macs. I expected no different from this new Western Digital (WD) 2TB drive.
    Unfortunately, the WD would not boot 2 out of my 3 Macs when connected via Firewire. It would NOT boot an Intel MacBook (Late 2007 edition) or an Intel iMac (Mid 2007 edition). It does boot our Intel iMac (Mid-2010 edition). Strangely, the WD booted all 3 Macs when connected via USB, though needless to say very slowly in all cases. If you need additional technical information, read on.
    Technical Info: The following tests were done with the WD connected via Firewire. The WD is correctly formatted for booting Intel Macs with GPT GUID formatting. Note that the WD appears as a bootable drive in System Preferences->Startup Disk on all 3 of my Macs. But when attempting to boot via Firewire, I get only a grey screen on the Intel MacBook (Late 2007 edition) and the Intel iMac (Mid 2007 edition). The Intel iMac (Mid-2010 edition) boots normally. When booting with the Option Key held down, Startup Manager does NOT see the WD as a bootable drive on the Intel MacBook (Late 2007 edition) and the Intel iMac (Mid 2007 edition). It does appear as a bootable drive on the Intel iMac (Mid-2010 edition).
    When connected via USB, the WD boots all three of my Macs, but very slowly compared to the internal drive.
    It's probably worth noting that the Late-2007 MacBook and the Mid-2007 iMac all share the then-new Santa Rosa architecture.    So I'm guessing that they may share the same Firewire chipset.   And for whatever reason, that chipset does not play nice with the WD chipset.
    So, bottom line is that if you need a Firewire bootable backup, be sure to test the drive right away so that you don't think you have a bootable backup when in fact you don't.
    On the good side, the drive is amazingly quiet. At this point, I need to decide whether to keep the drive, knowing that I have only USB as a bootable option on 2 out my 3 Macs, or return it. But in any case, wanted to pass this on to anyone else having problems booting from an external Firewire drive.

    FWIW, many WD HDs won't boot Macs and booting Macs isn't supported. Details at their site. That's the main reason I never recommend their crappy HDs.
    Actually I'm very familiar with that list- spent a lot of time looking at this past week! 
    Ironically, the majority of that page is a list of drives which they claim WILL boot Macs.  In fact, the list is entitled "List of Mac-bootable WD external drives..."
    And yep, mine is on there...on the list that reads "The following external hard drives should be bootable on Intel-based Mac computers systems through FireWire (1394a/b)" is "MyBook Studio" as well as my drive model number.
    But that's all beside the point.   Like you, I couldn't recommend their drives at this point.   At least make sure if you buy one that the vendor has a good return policy.

  • Intel iMac won't boot from disc or in safe mode - cannot repair disk

    I have an early Intel iMac 20" (2GHz core duo) that generally works fine. I recently ran Onyx and it reported a startup disk error, suggesting I insert the install disk, hold 'c', and use disk utility to repair the disk.
    NOTE: I have performed this operation successfully in the past and know how to do it.
    On this occasion, the iMac simply booted up to the normal desktop each time after multiple attempts at booting from both the original OSX 10.4.4 install disc and the OSX 10.5.1 install disc (current os is 10.5.8).
    I then attempted to start holding 'shift' to start in safe mode but again, repeated attempts all landed me on my normal desktop.
    I then attempted to hold 'option' to be given the choice of startup disc but again was ignored and went straight to my normal desktop after multiple attempts.
    Note that my iMac appears to be running fine otherwise. I was just trying to perform some routine maintenance and have run across this problem.
    Any ideas? This mac will be 5 years old soon and I would like to keep it running for a while longer.

    Hello Devoidarex
    You'll want to use the Leopard Install DVD to Repair your Startup Volume and may want to try a USB keyboard if your using a wireless.
    Another option is to insert the DVD and go to: System Preferences > Startup Disk > select the Install DVD > then Restart.

  • IMac won't boot from/install Lion. Why?

    I have a 2006-model iMac (iMac5,1 with a 2GHz Core 2 Duo processor and 2.5GB RAM; this is one of Apple's supported configurations for Lion) which has been running quite nicely for several years now. About a year or so ago I moved it to 10.6 which went smooth as silk. Last week I decided to move it to 10.7 and right about now I'm ready to throw this iMac in the effin' trash. It simply WILL NOT boot from OS X 10.7 no matter what.
    I first put my 10.7 installer on the computer while it was running 10.6. I launched it, it copied a bunch of stuff, then restarted the computer. Then....nothing. I got the Apple logo with the spinner. I waited about 20 minutes for something greater to happen but nothing did so I forced a shut down. Unfortunately that attempt seems to have destroyed my previous 10.6 installation. Any further attempt to start from that hard drive yields an infinite spinner with the Apple logo but never any desktop or anything useful.
    I then put my old iMac into Target Disk Mode, connected it to my newer iMac (iMac7,1 with 4GB RAM running 10.7.4), and used Disk Utility to reformat the old iMac's hard drive. That went fine. I then ran the OS X 10.7 installer on my new iMac, directing it to install onto the old iMac's hard drive. It took about 10 minutes to copy its files then directed me to restart which I did. I got the spinner-with-Apple for a few minutes followed by a spinner-with-circle-slash forever (about 15 minutes before I forced a shut down). I was able to reboot my newer iMac from its internal hard drive without any issues but every time I tried booting the newer iMac from the older iMac's hard drive I would get the spinner-with-Apple for a few minutes followed by a spinner-with-circle-slash forever thing. The same thing happened when I took the older iMac out of TDM and tried to boot it from its own hard drive. Trying that in verbose mode shows "Waiting for DSMOS" as the final line before the machine stalls. It is important to note that (a) this is a legitimately purchased Lion license that I bought last year, and (b) I'm trying to install it on an Apple iMac, not a Hackintosh.
    Next, I ran the Recovery Disk Assistant to create a bootable 10.7 recovery USB drive. The creation of the drive went fine and I'm able to boot my newer iMac from the drive — but I cannot boot the older iMac from it, again getting the spinner-with-Apple for a few minutes followed by a spinner-with-circle-slash forever thing. Verbose mode shows the DSMOS error again.
    My next step was to extract the "InstallESD.dmg" bootable system image from the installer app and clone that onto a USB drive. That went fine and I was able to boot my newer iMac from that drive but I was unable to boot the older iMac from that drive, again getting the spinner-with-Apple for a few minutes followed by a spinner-with-circle-slash forever thing with verbose mode showing the DSMOS error.
    Next I tried to reverse things. I put my newer iMac into TDM, connected it to the older iMac, and tried to boot the older iMac from the newer iMac's hard drive. This failed too. I never got the circle-slash thing, only the Apple logo forever. Verbose mode shows the last line being "BootCacheControl: Unable to open /var/db/BootCache.playlist: 2 No such file or directory".
    Finally, I pulled out a spare external hard drive. From my new iMac I booted from my USB drive (the one I cloned "InstallESD.dmg" onto), installed Lion onto the external drive, and booted successfully from the external drive. Everything was running perfectly. I ran System Update until everything was fully updated, then connected that external drive to the old iMac and tried to boot. Again, Apple logo forever with verbose mode showing the BootCacheControl error.
    To ensure that the older iMac was fully operational I dug out the old OS install discs and ran the "extended" diagnostic. Everything came up perfect with no errors.
    I then pulled out my OS X 10.6 DVD and tried booting the older iMac from it. That worked perfectly, and I was able to format and install 10.6 without any hiccups or issues whatsoever. The iMac is perfectly operational under 10.6.
    So why the phargl can't I get 10.7 on this bloody machine?!?!?

  • 2007 iMac won't boot from startup disc

    My brother passed away and I inherited his Mid 2007 iMac. Works fine, but all accounts are still in his name and I do not have his passwords. Trying to wipe the hard drive and do a clean start, but unable to boot from startup disc. It was purchased with Snow Leopard, but has been updated to Lion 10.8.3. It appears that there may be a security feature that rejects any attempt to boot from startup disc. Is there another way to wipe hard drive and start clean?

    Sorry for your loss ...
    The original startup disc will not work on a Mac running v10.8.3.
    The fact that you do not have the admin password is a problem because you will need it to repair the startup or restore OS X using OS X Recovery

  • IMac won't boot from Windows USB install stick

    I have a iMac 7.1, the first gen Intel iMac, now running Moutain Lion 10.8.2. I installed Windows 7 via bootcamp two years ago via a flash disk, and the installation was smooth and easy. Now I want to try some Windows 8. I used the Windows USB install tool to clone the install disk into a flash drive and tested the flash drive on a windows computer first. It was working properly. But my iMac just couldn't boot from the flash disk when I pressed the option button during start-up. There's no icon for the flash disk. Then I clone the old Windows 7 install ISO into the flash disk, it wouldn't show in the boot options either! Why? Is it because of some firmware update? Why the same Windows 7 install image I used two years a ago can't boot now for the same iMac? Please help. Thanks!

    I believe mende1's response is slightly incorrect. On older Mac computers that came with an internal DVD drive the only way to install Windows on those Mac's is from that internal DVD drive. Even if you connect an external DVD drive OS X and or the Mac computer Firmware will not allow the Win install DVD to boot from that external DVD drive. It must be done from the internal DVD drive. So if yours has failed then you would need to have it replaced before you can install Windows on your Mac.
    I know this from personally trying to install Windows from an external DVD drive even when there is an internal DVD still in the system. My late 2011 MBP would not load the Win install from the external DVD drive but would from the internal DVD drive.

  • 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.

    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.

  • 24" iMac Can't Boot OS X Install Discs

    I have a 24" iMac (A1225). I can boot to non-Apple discs (utilities, Windows) and I can even install Windows without any problems. I can't boot to any OS X Install disc however. I have the original 10.5 discs, they don't boot. I have a 10.7 disc that does the same. It starts to boot and makes encouraging noises for a bit but eventually both discs spin down with the Apple logo and the spinning circle which stops.
    Just for shiggles I tried to boot a couple of custom OSx86 discs (10.6.3 and 10.6.6). They both booted to the installer. 10.6.3 started installing (crashed half-way) but started to boot from the HDD after I restarted it (it didn't go anywhere of course, just the Apple logo). 10.6.6 finished installing but wouldn't boot after it restarted.
    It seems like there's a hardware issue but the fact that I can boot non-Apple discs and even install Windows without issue makes me doubt that. I have also cleared the PRAM (Option-Command-PR) and ran a quick test in AHT (D) without issues.
    Any suggestions on what I can check next?

    I can try it again but I think I've left it for more than 10 minutes Also, as I said, the spinner stops and the DVD spins down. Thanks for the reply!

  • IMac won't boot from HDD or CD.  Help!?

    Hi,
    I recently came back from holiday for a couple of weeks and sat down to start my iMac (24" C2D). The machine just sat at a white screen and wouldn't go anywhere. Thought, ah, I'll just reset the PRAM (unplugged power cable for a min or so), and still same problem. Eventually I got the mac to boot by holding down the power button, the long beep sounded and the mac booted. All was well, until the next time I powered it down. Same thing, however same resolution didnt work...
    After numerous attempts holding c, I've managed to boot into the mac installer, which said it couldnt repair the drive through disk utility. As I have time machine backup, thought I'll just start from scratch. Created a new partition (just to make sure everything was fresh), verified disk (no problems), started installer and it crashed towards the very end of the install (just over 1 hour in) with errors of being unable to copy files. After another few hours, managed to boot from CD again, this time install started, left it running overnight, only to find the mac in the morning on, but with a black screen. I've had to power it off and now I'm left with the same issue of a white screen and being unable to boot from CD.
    Does any of this make sense to anyone? Could be a failed HDD, but why would I have the issue with the iMac generally refusing to boot from CD? Ran hardware diagnostic (extended) and no problems found.
    I now have no hair left...

    I assume that model has a back up battery in it? If so, have you changed it recently? If not you may want to replace it. In the meantime, try removing it completely and see if it starts up any better. If the battery is right on the hairy edge of good/too low, it might be corrupting the PRAM (or whatever they call it now on new models) causing start up issues. If you remove it, you won't retain a lot of settings such as Date and Time, but you should also be able to boot up eat time with all default values.
    I had the same sort of issue with my eMac and pulling the battery cleared it up. That was many months ago and one of these days I might get around to buying a replacement battery... or not.
    Cheers,
    Patrick

  • PB won't boot from drive or disc: HELP!

    I can turn the machine on with the power button, and the screen displays the grey background with Apple logo, and the spinning barred circle underneath. The circle just spins and spins. Also, the machine is suddenly very loud--fan or drive making a clattering sound.
    I have tried to boot from the Hardware Test disc. I could get to the Open Firmware screen but when I try the "mac-boot" command, I get the following error message: "Invalid memory access." Also, the "eject" command would not open the drive device (though the disc did eject when I powered down).
    Also tried to boot from the Software Install disc. I can hear the drive reading the disc, but once the spinning circle comes up nothing else happens.
    Now I cannot eject the Software Install disc.
    Next steps? All help appreciated!!

    Virginia:
    Welcome to Apple Discussions.
    Let me see if I got this right.
    1. You can't boot normally from the internal HDD.
    2. You can boot from the Hardware Test disk, but no "Mac-boot"
    3. You can't install from the Install Disk.
    First try resetting the PRAM (Hit start button while holding down CommandOption+PR) and let it chime at least three times. Then release and see if it boots.
    If it won't boot restart and when it gets stuck in the Apple Logo grey screen do a hard reset (hold down the Power button for 10 seconds or so until it goes off) then try restarting.
    If you manage to get it to boot Open Disk Utility (Applications>Utilities>Disk Utility) select your HDD and run Repair Disk.
    Report back on any progress of lack of it.
