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?

  • I can not boot my mac pro 5,1 while holding Option key

    Hi,
    I have a mac pro 5,1 (3.33 six cores, 10.9 OSX) running a RAID 0 on a Sonnet Technologies PCI-E Tempo SSD Pro with two Samsung 840 pro 256GB.
    I would like to reinstall from a USB or recover the machine so I restarted it while holding the Option key.
    It did not work. What I have is just a white screen with the mouse pointer (arrow). I tried many time but nothing change.
    I restart with pressed C key, Command+Option+R....: nothing works. I reinstalled by downloading a fresh copy of OSX 10.9 but nothing helped.
    So I post here in order to get solutions from the experts.
    If you know what to do for my case then please help me out.
    Thanks and regards,
    nhvma

    installing OS X to a PCIe controller often won't work. What does:
    Install to a drive on SATA 2 bus, then clone it over to your RAID. And create the RAID with 10.9.
    Personally I have yet to read, hear of or experience in years that booting from arrays really helps. Larger volume yes but a single SSD is fine. Even putting one like yours on the SATA II bus and use the PCIe card for graphic library, for scratch, other uses where it does help and matters.

  • 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.

  • 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.

  • 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.

  • How can I boot from USB 3.0 disc on a Mac Pro 2013

    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't Boot From Install Disc 1 ?

    Holding down "C" at Start Up isn't working.
    Most of the time I can't get Preferences > Start-Up to even "see" my Disc 1.
    When I can get it to show up in Start-Up, and Select it, and Lock it ... it Still Won't Start Up from the Install Disc 1 ... and in fact usually ejects the disc.
    Sometimes when I re-push in the disc, I get the message that a Blank Disc has been detected, "what do you want to do with it."
    But, it shows up in Disc Utility, and when I run Verify Disc, it all looks good?!
    The Disc has Mac OS version 10.4.8 on it. I'm running 10.5.7. I'm all up to date with my software.
    Yesterday I ran the latest version of Disc Warrior. When I run TechTools 4.0 it seems to get stuck running Files. When I run Repair Permissions from Disc Utilities, it shows a fairly massive amount of issues. Running it over and over again doesn't seem to make any difference.
    I WANT to run my Install Disc so I can run Repair Disc from Disc Utility ... because I'm having a number of issues ... and I seem to get the spinning rainbow a lot.
    SUGGESTIONS ?! ... thanks ...

    Disk Utility that can repair a 10.5.7 permissions is only found on the Leopard installer disc. Tiger can't repair Leopard when it comes to permissions, and may also have difficulty with the directory.
    Secondly, if your MacBook Pro was purchased after October 26, 2007, it can't boot from any Tiger disc.
    If your MacBook Pro was purchased prior, you can use the disk, but you'll want to follow these directions for hardware diagnostics:
    http://docs.info.apple.com/article.html?artnum=303081
    Only if your MacBook Pro has Tiger installed, should you use Tiger for the directory or permissions*:
    http://www.macmaps.com/directoryfaq.html
    Macs can only boot from the operating system that shipped with them, and newer retail operating systems. This means:
    1. pre-October 1st, 2007 MacBook Pros can boot off:
    - - the discs that shipped with them
    - - retail 10.5 discs which look like * that do not say Upgrade, DropIn, or OEM.
    2. October 1st through October 25, 2007 can do #1, and also use Upgrade and DropIn discs. Those disks were offered as a limited time mail order Up to date program, some were dropped in the box that came with them.
    3. October 26th through November 14, 2007 can boot off the discs that came with them, and retail 10.5.1, 10.5.4, and 10.5.6 discs that do not say Upgrade, DropIn, or OEM, and have a label like the image above.
    4. November 15, 2007 through June 29, 2008 can boot off the discs that came with them, and the retail 10.5.4, and 10.5.6 discs that do not say Upgrade, DropIn, or OEM, and have a label like the image above.
    5. June 30, 2008 through December 14, 2008 can boot off the discs that came with them, and the retail 10.5.6 discs that do not say Upgrade, DropIn, or OEM, and have a label like the image above.
    6. December 15, 2008 and later MacBook Pros can only boot off the discs that came with them.
    Presumably when Snow Leopard comes out in September, all of the above will be able to use Snow Leopard because of the specs on http://www.apple.com/macosx/specs.html

  • 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.

  • 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.

    Hello jaqueline & Welcome to Apple discussions

  • Can't restore from Disk Utility while booted from OS installation DVD

    I'm absolutely astounded by this.
    I have a new MacBook Pro 17". I restored my files to it and in short order, had it too full/fragmented to re-partition it for Boot Camp.
    So I decided to image the disk and store that image file on a FireWire drive, wipe the system disk and restore it cleanly from the image file backup, hoping that would result in contiguous blocks used so that I could then re-partition for Boot Camp.
    When booted off the OS X for Intel DVD-ROM disc (10.4.6 - the one that came with my MacBook Pro), if I get out of Installer and into Disk Utility, if I select the internal hard drive and click the Restore tab, I can easily select the hard drive backup image with the button. But the "Destination Disk:" box is only accessible via dragging the disk to the box.
    There's one little problem - there is no Desktop, so the disk(s) do not appear on the Desktop. There is no way to drag the target disk to be restored to into the Destination Disk: box. You cannot drag a disk out from the little sidebar inside the Disk Utility window over to the Destination box. I tried. You can't drag any disk anywhere from that sidebar. It's clear that the only way to drag a disk anywhere is if it's shown on the Desktop in Finder (which isn't running when the installation DVD-ROM is booted from). There is simply no way that I can find to restore a disk drive from a saved backup disk image when booted from the installation DVD-ROM.
    Please tell me I'm ******** and missing something, or if there's a Better Way to do this. (I can't seem to run Retrospect while booted off the DVD-ROM, so I can't restore from my Retrospect full backup of the disk, either. Joy!)
    (I'm really curious if there's a Better Way - especially because it appears I can't boot from an external FireWire or USB 2.0 drive, so I need something that will work in this extremely limited installation DVD-ROM booted environment, I think.)

    You can use an external bootable drive with a MacBook Pro -- check your manual or the built in help. Your problem is that for some reason, you can't install a bootable system on one. There are several reasons why Installer won't enable you to do so: insufficient space, incompatible partition scheme (should be GUID) or file system (should be HFS+ or similar), or wrong installation option selected.
    It is possible this is related to why you can't drag the startup volume to the destination box in Disk Utility. It must be an HFS+ variant file system.
    I think you should check carefully with D.U. the partition scheme of all your drives & the file system format of all the volumes involved. Also run repair disk, as someone has already pointed out.
    The behavior with the Restore function is not normal -- you should be able to drag a volume to the destination box from the list.

  • Can't boot from OSX disc...

    I recently installed a 3rd HD. When I attempted to format it, I was unable to startup using the X disc. It would boot up in 9.1 off my HD. I was able to boot from the OS9 disc and format the new HD but now I can only see it while running in 9 and not in X. Anybody know how to boot off the X disc? I was hoping that if I can format the new HD from the OSX disc maybe that would help???

    Are you saying that it is impossible for any beige to run master/slave configurations in os x?
    It is a little more subtle than that.
    1) If you have duplicate masters on a cable, when Darwin (the UNIX underpinnings of Mac OS X) wakes up and looks around, it will declare both Masters unusable. If Darwin does not activate them, it's as if they are not there to Mac OS X.
    Darwin uses built-in Disk Drivers that are completely different from those in Mac OS 9. Users no longer have the benefit of all the extra forgiveness built into the traditional Mac OS 9 Drivers over the years. This has produced a rash of superstitions that various features "do not work under Mac OS X." The truth is that you must have hardware that meets the letter of the law to work in Mac OS X, it is no longer forgiving.
    2) If you have a drive accidentally set to Slave, Mac OS X generally will not install to it or Boot from it. Mac OS 9 may be perfectly happy with it.
    and Allan, thanks for your support!

  • I want to install my original SnowLeopard (from the installation disc) to a partition I created in the now upgraded Mavericks OSX, How can I install it on the new partition?

    I want to install my original SnowLeopard (from the installation disc) to a partition I created in the now upgraded Mavericks OSX, How can I install it on the new partition?

    That's easy.
    2 methods:
    1. Change the Startup Disk in System Preferences, then restart:
    2. Hold down the "Option" key while starting or restarting the Mac. Then chosse the partition that you want to startup from.
    The 1st mehtod is the quickest, because you don't have the additional step of choosing the drive. Plus, whatever you have selected in System Preferences becomes the default startup drive.

  • Computer doesn't boot. can't boot from install discs

    my quicksilver g4 running on os 10.3.9 has been booting up very, very slowly and once booted running slowly as well. so i was able to verify & repair permissions. however then the computer wouldn't boot up from the boot drive at all. i tried booting up from the install discs but when i tell it to boot up from the install disc it keeps returning to the installation menu. none of my installation discs (3) actually say on the label that they can booted from so i'm wondering if they're bootable. i try to run disk utility but it says it reading configuration for a very long time and never goes anywhere. i was able to run the hardware tests and it tells the video ram test failed with error code disp/13/2. can anyone shed some light on this mess? thanks.

    Hi! The video card failed test could be the result of the machine having a different card than the stock one that came in it or it could mean it's actually bad. The install discs are bootable by definition "IF" they are the correct ones for that machine. Retail OSX install discs are bootable but machine specific discs are only bootable on specific machines. The slow boot could be a bad hard drive. I would unhook the hard drive and try booting from the install disc to see if it will boot that way. Hold the "c" key down at startup with the disc inserted.
