Mac Pro not booting from disc

Hey folks,
I've got a Mac Pro and I've installed a clean HDD and I plan on installing OSX Snow Leapord (SL). When I insert the SL dvd, the mac stays stuck on the screen with the apple logo? Any ideas on how to get past this?

  • Mac Pro not booting from CD's using 'C'

    All of a sudden I am unable to boot from a CD. Every disk that I try will not boot. The CD drive will try to read for 5 minutes, then crash with that different language please restart your computer crash screen. I've tried DISKWARRIOR and MacOS X Leopard. They will not boot. I've cleaned the disks and reset the PRAM, but still won't work. All external connections are unplugged.
    3 months ago, it was working perfectly, I even did a clean install of Leopard. The only thing that was changed in my system, was an upgrade to the NVIDIA GeForce 88GT, but why would using a different video card force a crash during a CD boot?
    Otherwise, my MacPro is working perfectly and the disk has no errors. I can read, write, install apps and run movies on the CD ROM drives. but cannot boot

    Recently, I bought diskwarrior but it doesn't boot. I tried the Leopard install to test it out. That doesn't work, then I called Alsof and they said it should boot on my current system.
    DiskWarrior will not boot on a Mac Pro (Early 2008).
    "All Mac models meeting the system requirements for DiskWarrior *except the new Mac Pro and Xserve models introduced on 01/08/2008, the MacBook Air introduced on 01/15/2008, the MacBook/MacBook Pro models introduced on 02/26/2008 and the iMac models introduced on 04/28/2008* can be started from the CD."
    <http://www.alsoft.com/DiskWarrior/support.html>
    If you want to use DiskWarrior, you need to put it on another drive or partition containing OSX 10.5.4
    Therefore, all of sudden nothing boots. Like I said, the only change I did was to replace the video card.
    That's why the Leopard DVD won't boot. The Leopard DVD that came with the computer doesn't have drivers for the new graphics card. If you still have the old card, install it, install Leopard, update to 10.5.4, then put in the new graphics card.

  • After 10.5 upgrade Mac will not boot from hard drive

    I just upgraded to 10.5 Leopard but my mac will not boot from the hard drive even after selecting my hard drive as the startup disk. The mac will start to boot but will cut itself off before the boot is complete. I have to leave the Leopard disk in the mac and hold down C to get the mac to turn on but it only allows me to install the software again.

    instead of archive and install you might first want to try restoring your system using TM to some time point before your failed 10.5.1 upgrade. Then try upgrading to 10.5.1 again. I would suggest downloading the full 110 MB upgrade and installing it manually rather than doing it through the software upgrade menu.
    You can download the upgrade here:

  • Mac will not boot from hard drive or install disc

    Hello All
    In dire need of advise...my intel Mac will not boot, even tried booting to the Snow Leopard install disc and all I'm getting is the white screen, apple logo and the wheel.
    Just before this happened there was a buzzing sound like the fan was about to fail but that is only a guess on my part. Is there a keyboard shortcut to boot to a terminal window or similar to force the computer to boot from the install disc.
    Thanks in advance for any help offered.
    Warren

    Hi Warren
    Try holding the Option key and see if it will boot into Startup Manager, where you should be able to choose from a good Drive or your install Disk.
    http://support.apple.com/kb/HT1533
    or the D key and run the Apple Hardware Test.

    Also note: key commands may require a USB Keyboard if your using a wireless and it has become unpaired.

  • Satellite P300-1A8 will not boot from disc drive

    Hi,
    I had a little play with start up programs, partitioning the hard drive and marking as active and deleting programs i thought i did not need.
    I obviously had no idea what i was doing!
    Laptop will go to toshiba screen then goes blank, i can not boot from the disc drive.
    I put the hard drive into another laptop and it works fine.
    I put the hard drive of that laptop in the buggered one and that works fine.
    How the hell do i put the original one back with it working??
    Really really stuck with this!!!!!
    Any help would be appreciated.
    Only thing i havent tried is the recovery disc but im not paying for one if it wont boot as itl be a waste of money.
    Seems like its a compatability problem with cpu and hard drive as they dont want to be friends anymore!!
    Thank you in advance

    Hi!
    Can you boot in the safe mode?
    If you dont have a recovery disk, use the Microsoft installation disk and try to boot from it.
    And you said that you cant boot from disc drive, did you tried different disks?
    Maybe some are not readable or not bootable.
    The best way would be a recovery disk. The installation takes a few minutes and you have a clean installation with all drivers and tools from Toshiba.
    Bye

  • [URGENT] Mac Pro not booting, Fan error but fans are working.

    Hello,
    My server G5 is stuck on grey screen with spinning wheel. I ran the AHT and got the following:
    2FAN/4/8: CPU A INTAKE
    All the fans are spinning. I would really really appreciate if I can get any help or advice. I tried searching for this AHT error but could not find anything solid.
    This is our main server and its crucial to our organization and I am sweating bullets here.
    I reseted memory and unplugged all RAID drives. The three LED on the Logic board are Red, Yellow and Green; Power On, Trickle and Open Firmware respectively.
    Thanks for any help.

    Just to say that usually it helps to include the make/model of RAID controllers, whether it is hardware RAID or not. The Mac Pro Apple RAID card IS a PITA and is particular sometimes about drives and its battery reconditioning as well as mounting drives and time to create a hardware RAID5.
    When a drive causes trouble it is often though not always because of directory being damaged and OS X can't even inspect to see if there is a system or if it can be mounted.
    And because the G5 normally only has two SATA drives, to use three requires a bracket or something else to add drives, like Sonnet G5 Jive. And then a PCI SATA controller with internal ports. But that is just your average SATA controller.
    If it was a Mac Pro the thread could and should have been moved to another forum. And you still refer to this as a Mac Pro, not PowerMac. Which leads me to wonder.
    Molex y-splitters as needed in a G5 but three yrs for a set of drives, I'd say they were due for backup + erase/initialize and restore. Hopefully you kept them in shape with Disk Warrior during that time (don't rely on just Apple First Aid to maintain and repair/rebuild directories).

  • Mac Pro not booting after restore.

    Hi. Hopefully someone can help me here.
    Tried a total system restore from my leapard Install disk to a recent time machine backup of Snow Leopard 6.4 after a mishap with Mac Keeper (easily done I tell you)
    The drive seemed slow and unresponsive even before this and had initially spat out my two Snow Leopard install disks but I managed to boot from previous original Leopard disk after I shut the machine down for a while. Using utilities, I found the back-up required and started restoring some 435gigs worth which took 18 hours. At times the drive seemed to go to sleep. I was beginning to think that the drive was just about hanging in there with the odd behaviour that had recently happened. I had initially thought the disks must have been scratched but it was stating it could not read other disks too so I guess there is a definite drive problem going on.
    Anyway, eventually the next day my sceen stated that the mac was restored. Tried to boot. Gray sceen of death.  Telling me to shut down and reboot. Happened every time. Tried starting command +S.where it's stating "Mac OS not yet set". It wont let me type anything. Tried rebooting from leopard again to see what disk utility was finding. All seemed OK. The computer is seeing the drives and the content amounts. Tries varifying/repairing disks.  all OK. Tried repairing permissions on sysem drive which finished in a split second.  I'm thinking of changing the superdrive and backing up again but this may not be the problem at all. I did have a file that said previous system on the Mac for some reason separate to the system it was using. Could that be a problem here. Any help greatly appreciated. Thanks James
    Mac Pro - Snow Leopard 10.6.4  (2006-2008)

    Hi
    Thanks for replying.
    Yes I booted from Leopard install disk as the dvd drive wasn't seeing either of my Snow Leopard ones.
    From utilities menu I restored a time machine backup that I had done just before using Mac Keeper. This was meant to be a complete system install as I didn't know what files Mac keeper had moved. Though it took a long time, it finally stated that it was restored and I thought I was back in business. However gray screen shut down after a few 3 seconds of Apple appearing everytime.
    The DVD drive is not letting me boot on leopard install everytime either. Any thoughts

  • Updates on Mac Pro Prevent Boot from SSD

    Hey there everyone,
    I recently upgraded my 2010 Mac Pro (Quad Core) to an SSD Drive using the OCZ Petrol Drive and I coudn't be happier. The system is super snappy and works great. That said, I downloaded the latest updates to my system last night and as of today, it wont boot to the SSD. All other boot operations seem fine, but the SSD wont boot. It goes into the progress bar screen you get when a firmware update is running then just shuts itself down.
    I tried reseting the PRAM with no luck and also tried a disk repair from the Lion Recovery Partition as well as a Lion DVD I made, but both fail to repair the disk. I am currently recovering from a Time Machine backup and everything seems to be OK so far, but has this happened to anyone else with the latest batch of updates? I will update this post when the Time Machine Backup completes and let you all know the outcome.

    Update 2: I did a hard shutdown and rebooted holding down the option key to try and boot from the Lion Recovery partition and perform a disk repair only to find out the Lion Recovery partition was no more. Wow...looks like this is a bigger issue than I thought. Reinstalling Lion from a DVD now. This should be fun...

  • Mac pro not booting up

    Help my mac pro will not boot up gray screen with apple logo and the loading icon keeps going round and round but nothing else happening. Iam running Lion OS X (10.7) Help please

    hello,
    I've a 2.66 MAC PRO, with Tiger OS (10.4.10). I've same problem denounced by clarky99. Everything started a month ago, after some updates:
    - plug in manager
    - Java
    - utility airport
    - IDVD
    - Airport extreme 2008-002
    - security update 2008-007
    I've tried the following:
    - MAC OS hardware test: no problems
    - fresh installation of the OS on an external HD: no change
    - PRAM reset: no change
    - removal of the physical RAM cards: no change
    The only way to avoid the startup and video problems is starting in SAFE MODE (pressing shift key during the boot).
    This make me think it's an hardware problem, but I'm not shure.
    Next attempts:
    - try another video card
    - (time consuming) disabling all the processes which are not activated in SAFE MODE, but are started in the normal statup procedure, and then by re-enabling one by one
    Any further suggestion is welcome!

  • MacBook Pro not booting from CCC clone from earlier MacBook

    Hey, all
    A bit convoluted, but here's the deal.
    My wife bought a MacBook (back in 2009, the aluminum model WITHOUT firewire).  She got a new job that gave her a MBP that she can take home and do with as she pleases.  We decided to clone her MacBook's drive (was, at the time, running 10.5.7) to an external drive (USB 2) and wipe the MacBook to give to her folks as a gift.
    Long short, her MBP wouldn't boot to the external drive; my MacBook (same model as the one we cloned) did it just fine.  I figured since her new MBP came with Snow Leopard, I should upgrade the cloned OS so the BIOSes would match up.  I upgraded the cloned OS to the current version of 10.6, still no luck.  Again, it still boots up on my MacBook just fine, but not my wife's MBP.  I even created a partition on her internal drive and recloned the drive to it; I still get the same thing: chime, grey apple on white background...hang.  It never progresses beyond that, and it just sits like that for hours until I reboot to her "work" drive.
    I'm kind of at a loss, and don't really know how to fix this; I was hoping to make this easy for my wife so she can have her work and personal computers on different partitions of the same internal drive.
    Any suggestions?  The MBP is 3 months old, but was factory new.  The MacBook is a mid-2009 model, aluminum, user-replaceable battery, no firewire.
    Any help would rule.  Thanks!

  • Mac Pro will not boot from Leopard or any CD or DVD install disk

    My Mac Pro wont boot from my Leopard install DVD. It never gets by the gray screen, then after several minutes the screen scrolls down black and says I need to restart my computer. I tried my Tiger install disk and it still wont boot from that DVD. Held down the "C", used "option" and selected DVD and still no boot. I can boot from one HD that has Leopard 10.5.8, but another HD with Snow Leopard 10.6.3 will not boot. The HD with Snow Leopard shows up as "EFI Boot" not the name I gave that HD when I startup using the "option" key. Any help would be appreciated.

    At first I was just going to say it sounds like you have a bad optical drive, but then you had to go and say that it also won't boot from a HDD.
    That just makes things a whole lot worse.
    Start by removing the side cover and checking the RAM to see if any of the LEDs are lit up indicating bad RAM. Usually if there's any bad RAM found, it will just automatically disable that stick, but maybe yours isn't for some reason.
    Look for any other LEDs that may be lit. Generally speaking, the only time you should see an LED (outside of the power LED) lit consistently is if there's a problem.
    You should also see if you can get Apple Hardware Test to run, which may or may not find some problem.
    But sorry to say, it's sounding very suspiciously like a bad logic board.
    One other thing to try, is putting the SL drive into a different slot. So if you were putting it in slot 2, try slot 3 or 4. If you just have a bad SATA port, you might be able to just work around that until you get a new system.
    If by chance this system is still under warranty, do not walk, do not pass go, do not collect $200, RUN to the nearest AASP or Apple store to make it THEIR problem to sort out.

  • HT4818 Boot from laptop's Windows Hard Drive in Mac Pro via Boot Camp

    I have a work laptop that is on Windows 7.  It's a work hard drive so I don't want to mess with it (particularly as it's encrypted).  I basically want to use it on my Mac Pro rather than my piece of junk standard issue laptop when I'm working from home.
    What I would like to do is pull the drive out, put it in my Mac Pro and boot from it using Boot Camp.  Guidance I've seen so far talks about not being able to use an external drive but having to partition an internal drive.  However, if I've got everything on a separate drive (i.e. my laptop's drive), will this work?
    Thanks!

    Thanks for the quick (and no nonsense) response!

  • After OS Upgrade, Computer will No Longer Boot from Disc, Enter T-Disc Mode

    I purchased the Leopard update about a week ago and proceeded to install it (upgrade option) on my MacBook Pro previously running Tiger. After this update, I no longer seem to be able to boot from a disc(c on startup), enter target disc mode(t on startup), enter single user mode(command s on startup), basically anything that requires hitting a key on boot. In short, the operating system seems to override any of those commands and just loads regardless of what I press.
    How can I fix this?? I fear that if my mac suddenly dies, I won't be able to fix it with archive and install via the CD, since I can't boot from it. I also won't be able to recover my files with target disc mode or anything.
    For more in-depth details:
    -My hard drive does have an open firmware password- it was recommended as part of the undercover anti-theft program that I use. Although I can tell putting the password on was a mistake, since I've read that single user mode is no longer accessible with this password active. I don't think this is affecting my inability to boot from disc or target disc mode though, as I was always able to do this with Tiger, even with the firmware password active.
    -I have tried booting from other discs, like my old tiger OS disc that came with the laptop- that fails too.
    -My Leopard installation was not clean. Like many others, I used the upgrade option and it appeared to work ok- until restart, where I was faced with the blue screen. Since I was unable to boot to single user mode and try removing potential APE files, I let the computer sit for an hour on the blue screen until it finally loaded. Upon getting in, I found that I did not even have APE's installed. I proceeded to reinstall the operating system via an Archive & Install. Upon boot after this reinstall, I still received a blue screen that lasted a long time, and the OS loaded very slow. It did this for a few additional boots afterwards, and has appeared to smooth itself out now, a week later. The OS now loads fine and works alright (from what I can see), but I still can not boot from disc or anything else.
    If anyone at all knows a solution for this, it would be much appreciated. I wanted to suspect something like the disc drive going bad, but being that things like the target-disc mode aren't working either- I'm hesitant to believe its just the disc drive. Being that it also happened just as I upgraded to Leopard and faced issues, I have more of a hunch that its something to do with Leopard.
    I apologize if this has been answered before, but I've looked all over the site, google, everywhere I could think of and came up with no answer.
    Thanks ~Brian

    Hi, I have been having the exact same problem with a late 2011 MBP 15 inch. I replaced the hard drive with a samsung SSD 1.5 years ago, along with a samsung SSD in the optical drive. It worked great until the Yosemite upgrade. The MBP seemed to work reasonably well for a few days after the upgrade, but then it started stalling on various programs (spinning beach ball on Mail, Safari, etc). Start-ups were also longer and had a loading bar each time, which was new since the upgrade. I left the MBP to sleep last night and when opening it, it crashed and tried to restart. On restart it loads to the login screen, then after I enter the password it partially loads (based on the loading bar), then shuts off. I removed the SSD and plugged it in with a USG, but that didn't change anything. Here is a picture after using CMD-V before it shuts off.

  • Cannot boot from disc

    Holding down "C" does not boot from disc.  Computer does boot normally.  After entering password -- which is accepted -- there is no dock or access to apps.
    Reset PRAM does not work.

    I just found another possibility:
    So you cannot get to single user mode... can you get to open firmware, and reset the non-volatile RAM?
    Cmd-Opt-O-F at boot
    reset-nvram
    set-defaults
    reset-all
    (each line exactly as shown, followed by <return>)
    I'm now able to repair the volumes.  Waiting for it to finish and reboot.
