Imac wont boot from DVD

just got my imac back after hard drive replacement, but it will not boot from the dvd? and now I can't get the dvd out?

Zap the PRAM and Reset the SMC, then try again.
As for the stuck disc, this is the simplest, from LousyFool's link, if restarting, holding down the mouse doesn't do the tridk.
Open Terminal and type "drutil tray eject" to eject the disc/tray, and "drutil tray close" to close the tray. If you have an external drive, e.g. the MacBook Air Superdrive, use "drutil eject external".

  • 24" iMac - Wont boot from HD or disc... Help!

    Hi guys,
    Just been working on iMac, forget the exact spec but it's a 24" Intel 2.something Core 2 Duo or whatever it is, 4gb DDR2 RAM, gotta be about 2 years old to the day and after my last 2 Macs have lasted forever, never developing a fault, I didn't take out Applecare... Perhaps I had a bit too much faith...
    As I say, just working away and all of a sudden, upon putting a video in Quicktime to full screen, the whole image has kinda of condensed itself into the top 20% of the screen and started slightly flickering the image. I've tried quitting some of the programmes, but neither the mouse nor leyboard have been responding so I've just had to turn the computer off.
    I've gone to turn it back on, and after about 30 seconds, it's got as far as the grey screen but then the little spinning progress indicator pauses and it does nothing else.
    I've reset the PRAM and that made it take longer before it froze but ultimately did nothing.
    I've now tried getting it to boot from the Snow Leopard disc but this does the something, until after about 3 - 5 minutes, the screen goes all pshychedlic, like looking at an old school TV really close...
    So looking for any suggestions on other things to try before I have to take to my local store... Any hazard a guess at what may be up with it?
    I've got a back up the whole computer but I don't think this is a software problem, I'm assuming it's going to be a hardware one?
    Any help at all would be much appreciated!

    Ok, tried Safe Mode and that wont boot either. Saw a little progress bar on the grey screen though which made a change, but ultimately, it crashed once that had disappeared.
    I've just noticed that at the point when the progress wheel stops spinning, a pattern of dead pixels appears across the screen that aren't there when the progress wheel is spinning.
    The more I talk to people about this, the more graphics card seems to come back as the likely culprit, based on the fact that:
    - it started by me putting a video to full screen
    - the fact the display went weird when it first happened and also it plays up after it crashes with the psychedelic colours
    - it wont boot from HD, disc or now in safe mode either, however it does run AHT fine.
    - I've hoovered out the vents on the iMac and somehow it seems slower than it was before (bit odd)
    - the dead pixel thing mentioned above
    So now thinking it may be time to get a new graphics card?
    Reckon this is likely, even though the AHT hasn't picked up any problems? As mentioned earlier, I'm not too concerned about it would seem it doesn't particularly test the graphics card too much, so all just seems to point towards it.
    Anything else that I could do to single this out as the likely culprit?
    Guess this is a chance to upgrade!

  • IMac wont boot from CD

    I am selling my iMac so want to reformat the HD and do a fresh install of Leopard.
    When I try to boot from the system CD I get the grey screen, I hear the CD Drive reading the disk, then the computer reboots. The same thing happens every time no matter how I try to boot from the CD. When I eject the CD, or boot from HDD, it loads the OS fine. It just wont boot from the CD.
    I have tried:
    Booting from CD by holding the C key during startup
    Booting from CD using Startup Disk in System Preferences
    Installing OS from the 'Install Mac OS X' application on the disc
    Holding the option key during startup and selecting the CD drive
    Resetting the NVRAM
    Verifying the HD in disk utility
    Verifying the CD in disk utility
    Verifying and repairing HD disk permissions in disk utility
    Running the install on my MacBook to check the CD (booted to the CD and started install process fine)
    I have searched for previous discussions that reference this issue but could find none with this specific problem. The CD drive reads other media fine so I don't think it's a hardware issue.
    Any help would be much appreciated.

    Clean the disk?
    Dirty lense?
    The bottom of the disk must be free of scratches and especially human fingerprints which the oils can trasfer insdie the machine.
    Use a bit of rubbing alcohol on a very soft clean cloth and polish ot a shine before using the optical drive.
    Order a replacement disk from Apple, buy jewel cases that suspend your disk, the plasic/paper sleeves Apple provides aren't good.

  • My imac wont boot from the install disk

    My IMAC will not boot from the install disk.

    Hello, your installation disk is running under OSX??? If no the media has a problem!!!
    1. Restart your mac and hold the alt (option key) to select media to install.
    2. Restart you mac and hold the "c" key to boot.
    an other solution is to make a partition on the hard drive and put a restore image of the Mac os X Installation dvd inside it then Restart your mac nad hold the "option" key and you will see the partition with mac os x installation and you can make a new installation from there.

  • Imac wont boot from cd, Can anyone help me Please

    Hello, I just bought my first mac from a co-worker. it didnt have a hard drive so i threw a spare one i had in. I tried holding c when booting, and all i get is the little smile face and the ? on a folder. At first when i booted the computer it didnt make any sounds. Then i found that the apple key option pr resets something. So i tried that. It now plays sound when i first boot up. But still can't get into the cd. I also tried the optionapple+fO. It came up with a screen and i did the reset-nram. but it couldnt find the command reset. Im so lost here. Im hoping i didnt waste my money. Any help here would be great. But please remember that i no NOTHING about macs. So please explain what you need me to do. Thanks alot
    Also let me know if you need more information

    As Robert suggested, the responders here will need to know what model of iMac you have, most importantly whether it is a slot load CD, or one of the older tray load models. The tray load ones have the slide that extends. The slot loaders suck 'em in.
    If the CD drive is functioning, your Mac will boot from your original install CDs, or a "Universal" OS9 (White background, Orange "9"). Once booted from the CD, open the "Utilities" folder, choose the Drive Setup utility, and initialize, or partition and initialize the drive. (Post back here if you need help on that step)
    If the CD drive doesn't work, try cleaning it with one of the commercial cleaning disks. If that doesn't work, they are replacable using a takeapart like iMac takeapart - link. Replacements are available on eBay.
    Remember to fold the front foot forward once you start using the iMac. 350MHZ and above have no fan and are convection cooled. The foot in the forward position allows better cooling.
    Good luck, and ... take your time. These are great little machines!

  • PowerBook G4 1.33 wont boot from DVD drive after upgrade

    Can anyone offer some assitance. I just upgraded my PowerBook G4 1.33 from a Combo Drive to a Panasonic SuperDrive. Also upgraded to a 250GB harddrive. Got a tree error on HD and when I went to boot up Diskwarrior I could not boot from the DVD drive. It does not come up as a bootable drive. Tried Holding down "C" key "Option Key" nothing works. Can anyone tell me what's wrong? All other drive functions work perfectly.

    Hi chubbs899, and a warm welcome to the forums & Macdom!
    i have read says you can go in through disk utility and partition the drive but i still have yet to see anything that says something about disk utility.
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    How to format your disks...
    http://www.kenstone.net/fcphomepage/partitioningtiger.html
    Thanks to Pondini, Formatting,  Partitioning, Verifying,  and  Repairing  Disks...
    http://web.me.com/pondini/AppleTips/DU.html
    it gives you the option of doing "journal" format or "case sensitive, journal" format.
    Don't use Case Sensitive, confuses many Apps.
    i suspected jumper settings but when i read through the manual on the WD website it didnt seem to say anything about doing something specifically for apple. it had a jumper for slower transfer rate 1.5Gb/s
    Yes, it needs that jumper on pins 5&6.

  • Installing Box Set SL on new iMac - cannot boot from DVD...

    Hi MacHive
    I downloaded Lion today but wanted to install SL on a external USB-Partition because there are 2 PPC games I still like to play every now and then (Homeworld 2 and Alpha Centauri). Then I can boot into SL on my external drive and play the games from there, and having Lion and everything else on the internal HD.
    So I started the install (after Disk Utility successfully verified the target disk), it succeeded into copying all the required .pkg into place and at the end of the installer log there are the following messages:

    At that time, it should restart with the DVD and finish the installation. However, I get the BONG! (good)  and the grey apple  (good), but then it stops (I never get to the grey moving circle  ;-) and soon after, the DVD stops spinning in the drive and nothing progresses anymore.
    Retrying to restart normally: same effect. Restarting with "c" key: same effect, restarting with "alt" key - I get my internal HDs and the DVD to choose (but obviously not my target disk), but choosing the DVD results, once more, in the same effect.
    The disc has no scratches and I used this disc to install SL successfully some time ago.
    Do you know how I can bring SL to the external HD? Is this iMac "too new" to be restarted with the Box Set Mac OS X  (supposedly, this is 10.6.0 or so... don't know).
    Any help would be greatly appreciated, thanks in advance!
    Kind regards,
    Fabio
    PS: I'm running the following (a 2011 i3 iMac):
    Jul 30 23:30:14 blop-imac Install Mac OS X[301]: Hardware: iMac11,2 @ 3.20 GHz (x 4), 4096 MB RAM
    Jul 30 23:30:14 blop-imac Install Mac OS X[301]: Running OS Build: Mac OS X 10.6.8 (10K549)

    Thanks Linc....   In an embarassing lack of concentration I didn't think that I should use the iMac's original disks (10.6.4) and not the box set one (10.6.0 or so). This solved the issue and I could install SL without further troubles. TY again.

  • IMac 24" Aluminium - No way to boot from DVD

    Dear all:
                 Thank you for having this forum fully working.
    My iMac 24" Aluminium (november 2008) can't boot, completely frozen, although all HW are perfectly working.
    I'll try to explain the issue best I can.
    SYMPTOMS
    - Grey screen of death without Apple's logo.
    - No bootable devices detected (either HDD or DVD) by EFI, when you hold ALT (Option) while booting.
    - No way to force boot from DVD.
    CAUSE OF PROBLEMS
    a) HDD has 3 partitions created by DiskUtils:
    /dev/disk0s2= Mac OS(HFS+)
    /dev/disk0s3= Linux DVD Installer (FAT32)
    /dev/disk0s4= User Data(HFS+).
    b) rEFIt installed and fully working on the system ( http://refit.sourceforge.net/ )
    c) Linux DVD installer partition was filled this way:
    dd if=/path/to/linux.iso of=/dev/disk0s3
    As you can see, there are no HW errors at all, everything was perfectly working before dumping the Linux iso into FAT partition.
    TRIALS FOLLOWED (and all its combinations).
    TRIAL 1 - Erasing EFI values on memory.
    Leave the iMac disconnected from power cord a whole night for memories to loose their values.
    http://www.youtube.com/watch?v=JId524890zc.
    TRIAL 2 - Force empty memories during boot.
    CMD+ALT+P+R -> Result OK (reboot)
    CMD+ALT+N+V -> No effect
    CMD+ALT+O+F -> No effect
    http://support.apple.com/kb/ht1533
    TRIAL 3 - Force boot from DVD.
    C while boot -> Read DVD first, but can't boot.
    http://support.apple.com/kb/ht1533
    TRIAL 4 - From Startup Manager, try to boot from DVD.
    ALT (Option) while boot -> See cursor arrow on screen, can't see DVD as boot option.
    a) Try with DVD already inside the unit.
    b) Try to insert DVD once I see the cursor arrow on screen.
    https://discussions.apple.com/thread/1383424?start=0&tstart=0
    TRIAL 5 - Remove RAM memories to reset EFI to factory defaults.
    - Remove all RAM from unit.
    - Boot from DVD (C key hold) -> Unit beeps.
    - Shutdown and fill one bank with memory.
    - Wait 15 minutes for EFI memories values to be deleted.
    - Boot from DVD (C key hold) -> Access DVD first, but no boot.
    TRIAL 6 - Boot from external Mac (Firewire + PC fully working).
    This is the only trial missing before replacing the HDD of the unit... finger crossed.
    http://forums.macrumors.com/showthread.php?t=271975
    IDEAS AND CONCLUSIONS
    - Any more ideas?
    - How is it possible that a SW problem affects the HW in a way that can't be booted from DVD? Somethings is terribly wrong on iMac EFI design... terribly poor stability.

  • Satellite C50-A634 wont boot from USB or DVD

    My new toshiba Satellite C50-A634 wont boot from usb, or dvd ,
    i have downloaded win 8.1 and burn image to dvd but i still get an error message "no bootable device......please restart system" .
    Can some one plz help?

    Hi
    Does Satellite C50-A634 supports internal CD/DVD drive or did you try to boot from external optical disk drive?
    You have to know that _Satellite C50 & Satellite C50D models *without* a built-in ODD_ are not able to boot from an external ODD due to a technical limitation.
    Details here:
    [Limitation of external boot media for Satellite, Satellite Pro C50 & C50D devices|http://aps2.toshiba-tro.de/kb0/TSB3B03JA0000R01.htm]
    Only USB flash drives are supported as external boot devices!
    It is necessary you can use a USB flash drive as recovery media on notebooks without a built-in ODD.

  • My 27" iMac Freezes, Won't boot from DVD

    My iMac has started to freeze up every few minutes.  Every so often, it becomes unresponsive; the mouse cursor still moves (sometimes it turns into a beach ball), but I can't click or type anything.  Whenever this happens, the hard drive begins to churn as if it's reading or writing something big.  This usually lasts only about thirty seconds to a minute, but it's happening with frustrating regularity. 
    I've been trying to troubleshoot this for a few days, now.  I'll walk you through the steps I've tried so far. 
    I ran a check on the hard drive with Disk Utility.  This came back with a message about the files/directories not matching up with their expected counts.  The solution it suggested was to boot from a Snow Leopard disc and let Disk Utility run a Repair Disk while the startup drive is not mounted.  It was at this point that I realized that I couldn't boot from the dvd.  Whether holding 'C' or 'Option', when it tries to boot from the disc, it gets to the Apple logo and then hangs. 
    I kept researching and found a workaround; boot into Single User Mode and perform fsck, which fixed the Disk Utility error, but did not solve the freezes/noises, and I still can't boot from the dvd. 
    Any ideas? 

    Thank you for your prompt response. 
    Well, I'm not sure if I explained it clearly.  Holding the Option key does indeed bring up a list of bootable devices.  The problem arises when control is passed to the Snow Leopard disc.  The Apple logo flashes, I can hear the optical drive being accessed, but then it locks up. 
    I should also clarify that it's not the disc that came with the iMac.  I just moved and can't find the original disc, so I borrowed my neighbor's (which came from a Macbook he bought after mine (which I bought last year)).  I am under the impression that Macs can't boot from discs that are older than the version of OS X that they shipped with.  I wouldn't think that's the issue, here, as his came out later than mine, but I've still got a lot to learn about life in the Appleverse. 
    My data should be safe--I've got an up to date Time Machine backup on an external drive.  The performance issues aside, I'm really looking to understand the underlying problem(s) here. 
    So, one option is that the RAM might be bad.  I can test that by swapping out each DIMM and checking if the problem is resolved.  One thing I don't understand, though, is why bad RAM would manifest as the hard drive being accessed.  Is there a definitive way to test the logic board, as there is for testing RAM? 
    Also, I keep thinking of other little syptoms which may or may not be related. 
    Recap of Symptoms: 
    Magic Mouse occasionally loses its magic (right click, multitouch, etc.) and needs to be turned off and on. 
    Free disk space fluctuates by as much as eight gigs (without my intervention). 
    System stalls (accompanied by HD access sounds) multiple times per hour. 
    Can't boot from dvds (though, this could be a version problem). 
    **Fixed:  Disk Utility Verify Disk error. 
    I do understand that this might be a hardware error, and I certainly know how much trouble that sort of thing is to find/fix.  I'm definitely willing to open the case and swap out DIMMs and drives, but not until I've exhausted my software solution options.  *crosses fingers* 

  • Macbook Pro Wont Boot from Retail 10.6.3 DVD

    Just like the title says.  It wont boot off the retail 10.6 disk I got a couple weeks ago.
    I think my EFI partition might have been corrupted...so I want to repartition the HD and reinstall the OS but the computer wont boot from the DVD.
    Any ideas?

    Hi Alexander,
    If your MBP shipped with an OS later than 10.6.3, it won't boot from that disc. Use the install disc that shipped with your MBP.

  • MBP i7 17" wont boot from external CD/DVD

    I have installed a second hardrive in my mbp using the optibay. Since then ive been trying to install windows on the second harddrive, but it wont boot from the windows cd. After some testing, it turns out it wont boot -any- cd from an external cd/dvd drive.
    When i put in a bootable cd and boot with the option key, it does recognize the cd. When i select it, it starts spinning up, stops, and i get a grey screen with an flashing apple/failed sign.
    I have already tried the following:
    - Reset PRAM
    - Use the superdrive i removed as USB cd/dvd drive
    - Use a different USB cd/dvd drive
    - Tried to boot off a bootable USB memory stick
    - Installed rEFIt boot loader.
    - Tried the (USB) superdrive on a previous model 15" MBP, and it boots without problems.
    Im at a loss what else i can try. OS X installed perfectly when the superdrive was still connected to the internal SATA connector, but i dont feel like switching the whole thing back. Not to mention i wont be able to install windows on the secondary drive.
    Maybe i could try an ExpressCard SATA controller? Or would that be a waste of time/money? Im also considering installing through target disk mode, but im afraid ill run into all kinds of trouble.
    I hope you'll have some ideas!

    I think can wrap this up.
    The OS X Installer that came with my MBP did work on the external USB superdrive. So it appears the same thing applies for any USB connected device: only OSX installer will boot from it.
    As for my initial booting needs: i have successfully installed Windows using bootcamp, though i used a workaround so i didn't have to boot from cd. For anyone who wanders around here and wants to know:
    - Created a 10GB VMWare disk image for Windows
    - Booted windows install disk inside VMWare
    - Upon first reboot i shut down the virtual machine
    - Connected the 10GB VMWare disk image to a Debian virtual machine
    - Ripped mbr using: dd if=/dev/sdb bs=1 count=446 > mbr
    - Copied it to my mac, and installed it to my drive using: fdisk -u -f mbr /dev/rdisk1
    - Copied over the VMWare disk image to my Bootcamp Assistent created partition using: dd if=/dev/sdb1 | ssh root@mymac "dd of=/dev/disk1s3"
    - Used WinClone to make an image of my Bootcamp partition, and immediately restored it. This fixes some windows issues for the new partition, and resizes it to fit your bootcam partition
    - Reboot into windows and the install will continue!
    Some tweaking of these commands are needed. If you don't know what you're doing: don't.
    Any questions, feel free to contact me.

  • Imac wont boot

    My late 2008 iMac wont boot. I have tried everything that i understand but cannot accesss harddisk.
    I cannot boot fron dvd -cd or usb. I would like to run diskutil from terminal to repair and verify. System hangs/ stops running, when i try command+v ,message that (vmcl: Module initialized.)
    Command + s puts me in single user mode and i cannot run diskutil.
    Safe start is also not working.
    I have all my work on imac and depserately need help.
    Any ideas ???
    Imac 2008 24" 3.06GHZ/2GB/500GB/SD8X/GF8800GS/512.
    Downloaded and installed Lion recently, all software is ligitimate.
    Running vmware / Vista, occasionally.
    Machine just stopped, froze up.

    Hei, just to let you know. I gave up and delivered my machine to mac repair. It turned out that a module error was the cause of my problems. They have since replaced the defective part and my machine works like a dream. No reinstalling either, all existing files and software are intact.

  • IMac Wont Boot Question.I cant find an answer.

    Ok Heres the story.
    I have an iMac 20" display Intel Core Duo.
    I came home yesterday and it was locked up.. I had to turn it off manually.
    When it rebooted it started up but was stuck with a folder with a "?" on it.
    I know it has to be the HDD.
    I booted it from the snow leopard DVD and went into disk utlilty and repaired and verified the disk. The HDD shoes up in disk utility with the Macintosh Partition.After I repaired it it still does not appear as an option to st it as a start up disc.. I dont think the HDD is bad.. But I am not an expert
    To be honest I dont care about the iMac I just want the data. I back up but I did not do one in a month or so and there are some things I want. If I removed the HDD and plugged into another mac would I be able to get the data off? I have one of those sata to USB adapters..
    Any help would be appreciated let me know if you have any ideas

    Do you know why it shows up in Disk Utilty but it wont boot from it?
    Because the computer can't find a bootable OS on it. This is much more complicated than just seeing the drive.

  • My imac wont boot  and a small square shows up next to the cursor

    Hi
    my imac wont boot and a small square shows up next to the cursor. I can open in safe mode. I have reinstalled the OSX, but can't boot from back-up.
    Any advice?

    OK.....I figured it out.....after reading endless threads on the cursor issue, I found out that apple calls the cursor a MOUSE POINTER..! and the square that follows it a 'corruption'...GO FIGURE!
    Anyway, this is what I did.
    I tried reinstalling Mountain Lion....online install. It didn't resolve the issue. Same problems
    Then, I tried reinstalling from the original DVD install disc....this wasn't possible (no access sign over install icon).
    So I finally erased my hard drive (after rebooting command - r), BUT NOT BEFORE BACKING UP MY FILES, APPLICATIONS, SETTINGS and any other important data!!!!!!!
    Then started up command R
    Then reinstalled Mountain Lion online
    My iMac started up like it does when you install 'out of the box'...follow the instructions....
    my cursor, or mouse pointer is now free of it's 'corruption', and boots up just fine!
    Hope this helps anyone out there with the same issue
