No boot disk found when system is turned on

Hello all, and thanks in advance for answering my question. I booted my intel based iMac from an Ubuntu Linux live cd to install Linux to a partition that I had set aside using disk utility but did not end up installing Linux. When I restarted the computer after removing the Linux CD, the screen was white for a few seconds longer than normal and then an error message appears saying that now bootable volumes were found and please insert a bootable disk and so I put in the OS X install disk that came with the computer but it still refusies to boot and does not respond to key presses at power on so I cannot eject the OS X DVD. Any thoughts on how to fix this?

Welcome to the Apple Discussions.
Have you tried starting up while holding the Option Key? That will take you to startup manager and you can select the startup disk.
When you started from the OS X DVD, did you do that while holding the C key?
You can also do the PRAM reset by starting up while holding command-option-P-R keys.

  • Can't find boot disk (only when restarting)

    I resently changed the HDD in my old macbook air and now I have a strange issue. When the air is restarted either manually or due to a software update the boot disk can't be found. If I do nothing the folder with a question mark appear, and if i hold down option-key no drives appear for selection.
    The weird thing is that it is only on restart. If I turn of the air and start it everything works properly. Because of this it is not a major issue but I would like to resolve it none the less...
    Thanks in advance

    Thanks - already did that several times though. It has become progressively worse and I have found that others upgrading to runcore SSD's have had similar issues.
    I will try a firmware update once i get the time, but I'm not optimistic... Keep away from runcore seems to be the lesson after what I've read so far in different threads

  • No Hard Disks found when installing

    Hi,
    Because I have a new PC that has a motherboard that has a kind of RAID controller onboard that is not (yet) certified by Sun, I've been trying to install Solaris 8 on a somewhat older PC. It's a P133 with 96 MB RAM and a 2.5 GB HD (IDE).
    Altough the Configuration Assistant finds my HD and CD ROM (and there are no conflicting devices), when the Web Start Solaris Installer looks for a hard disk, he reports: "No hard disks found on the system. Please see your documentation."
    I've been trying to change parameters in the BIOS of my PC: set hard disk mode from LBA to CHS or Auto, but I keep getting the same result. What is also funny is that I can issue the 'format' command after the installer stopped. There I can use 'fdisk' and I can create x86boot and Solaris partitons as I like. (I cannot format them though.)
    What 's going wrong?
    Best regards,
    Dominiek

    Did you try: destroying the "x86, Solaris" pair, re-booting, running installer, recreating "x86, Solaris" and re-starting the installer with "/usr/sbin/c0d0_isntall"? I have to do that EVERY time...
    HOWEVER !!
    Your drive might have a drive manufacturer LBA scheme installed - which may not be compatible with your BIOS LBA scheme (docs can be found on www.westerndigital.com). Frequent disk errros is one symptom.
    You should have the install disk for your particular hard-drive. It will indicate whether a drive-manufacturer LBA is installed. You BIOS setting is of course a separate issue.
    1) If you have an existing partition: * do not alter the LBA scheme *
    2) In general, partitions with an Operatitng system installed when LBA was enable must have the exact same LBA (by BIOS manufacturer, BIOS version, or hard-disk manufacturer) SUPPLIED AT EVERY BOOT. Some OS's ignore the BIOS's LBA offering.
    3) The LBA-written data is NON-REVERSIBLE. LBA written data is, in general, PER-PARTITION. You must do a complete backup, format, and restore to change you LBA scheme.
    4) If you don't know your complete LBA status - you should be concerned. In general, move away from LBA when the opportunity arises.
    You might contact your motherboard manufacturer upon the matter of obtaining a BIOS upgrade. Also: what brand HD do you have?
    Hope that help,

  • No boot disk found

    I'm using a Mac mini,
    OSX mountain lion or mavericks ( not sure if it's been updated)
    Using apple wireless keyboard and mouse
    Backup end up to external HDD using Time Machine
    I recently purchased a seagate wireless plus 1TB hard drive. During its setup I needed to reveal some hidden files in its media library, so I research how to do it on google and used 'Terminal' to display hidden files in finder. I used the command -
    "defaults write com.apple.finder AppleShowAllFiles TRUE"
    After doing this I restarted my Mac mini in the normal way. I did not use the KillFinder command.
    The computer powered up
    Gave a power up tone
    Displayed a blank grey screen for around 30-40 seconds
    Displayed a black screen with the message " error loading operating system "
    I powered down the computer by holding the power button, removed USB peripherals including HDD used as 'Time Machine' backup then restarted to be greater with-
    A power up tone
    A blank grey screen for 30-40 seconds
    The a black screen with a message " no operating system found -- insert boot disk and press any key"
    After a online chat and phone call from apple i'm no further on. I've been told that I need to go to an apple store or an authorised repairer.
    I tried starting up holding the option key,
    """" the shift key
    """" the Command + R
    With no joy
    Can anybody advise ??

    During its setup I needed to reveal some hidden files in its media library
    What hidden files? What media library?

  • No boot disk found after recovery

    Hi all. I have a problem with my laptop. I own a hp pavilion dv6  VJ703EA#B1A and recently i tried to restore it to factory settings via hp recovery manager. An error occurred during the process and after that it couldn't boot showing me the message that it didn't find a boot disk. I got an ubuntu linux cd and saw that all the partitions are lost. I proceeded and installed ubuntu but now i want to ask if there is a way to get back hp recovery partition and reset my laptop to factory state. Thanks in advance.

    Hi:
    Below is the link on how to order recovery disks for your notebook.
    http://h10025.www1.hp.com/ewfrf/wc/document?docname=bph07143&tmp_task=solveCategory&cc=us&dlc=en&lan...
    I have a workaround that you can use permanently or until you get your set of recovery disks.
    Scolton:  You can do this for your Toshiba too, and not have to worry about what you do when the W8 preview license expires.
    If you can read the 25 character Microsoft windows 7 product key, you can download plain Windows 7 ISO files to burn to a DVD for the version of windows that came installed on your PC, and that is listed on the Microsoft COA sticker on your PC's case.
    Burn the ISO using the Burn ISO option on your DVD burning program and burn at the slowest possible speed your program will allow. This will create a bootable DVD.
    Use the 25 character product key on the PC to activate the installation.
    The key will activate either a 32 or 64 bit installation.
    Then go to the PC's support and driver page to install the drivers you need.
    Link to the W7 ISO file downloads is below.

  • Comp won't boot, disk repair through system CD fails

    my power mac froze, and won't boot. i'm running 10.4

    system CD in drive, won't boot from holding down "c"

    now, when i try to run utility to repair permisisons, i get an error stating "disk utility has lost its connetcion with the disk management tool and cannot continue. please quit and relaunch disk utility"
    happens over and over.
    when i try to repair disk, i get a red line saying "reserved fields in the catalog record have incorrect date, keys out of order. the volume could not be repaired"
    Error: the underlying task reported failure on exit (-9972)

    SOOOO.... i'm stuck. can't boot, can't repair, can't do anything. any other possible suggestions before i throw this thing away?
    thanks

    Yes, Like I said, it sounds like the Drive is dying, but in SU mode you might try...
    /sbin/fsck_hfs -f
    Or possibly stronger Disk Repair tools...
    Your best bet is DiskWarrior, you need the CD/DVD though.

    But others that may work…

  • Creating a boot disk with minimal system

    I just upgraded to Tiger. I have an external FireWire drive that has two partitions. One (large) partition is for a backup of my Mac's entire hard drive. The other (much smaller partition) is a boot drive - that boots from Mac OS 9. It's time to update the OS on the boot drive (and put a copy of Retrospect on it - in case I ever need to recover from a disaster).
    My question is, how do I install a "minimal" system (10.4) on the smaller partition, and make it a bootable drive. The partition has 4.0GB of space. (I hope 4 gigs is enough.)
    I apologize if this question is already answered elsewhere on this site. I looked in the knowledge base and in several forums and couldn't find the answer.

    Hi Clinto
    Those 'minimal' installs date back to a time when you could run a Mac with just the System, the Finder and a couple of extensions. (Well I exaggerate but you know what I mean.)
    They would omit most extensions, inits and control panels (QuickTime, AppleScript, networking, printer drivers etc etc), the idea being that you could squeeze the bare bones of the OS onto a floppy and boot in an emergency.
    When you install OSX you are offered options not to install printer drivers or foreign language packages. And that's about as minimal as it gets. All the key technologies do get installed, along with the standard-issue applications like Safari, Mail, TextEdit... They're inextricably linked in a way that the elements of the different Classic OS's never were.
    The page referred to above says you need a minimum of 3GB of install space for Tiger.
    Hope this helps.

  • Pages & Numbers crashes when opening a document ,no documents found when iCloud is turned off

    I have just upgraded my iPad to IOS7 and my MacBook Pro to mavericks running the latest iTunes and also update pages and numbers.both crash when old documents are opened and the programs will only function if iCloud is switched off in settings but only when creating new documents .I have upgraded for more storage space and have 6GB free, many of my documents are invoices and are now unavailable to me so the situation is becoming quite desperate.
    Any help would be useful .

    Hi Amy
    Welcome to the forum.
    There are a few bugs in Snow Leopard.
    You need to upgrade using the downloadable Combo OSX 10.6.2 upgrade.
    http://www.apple.com/downloads/macosx/apple/macosx_updates/macosxv1062updatecomb o.html
    Do not upgrade using Software upgrade.
    The principle cause is a damaged Hoeffler Text font.

  • Cannot get MacPro to allow me to boot to an alternative boot disk. Can choose in control panel but will not use the disk to boot. Also won't boot using disk selected using option key

    My primary boot disk is encrypted as is a secondary boot disk (backup) but I cannot boot using any other disk. System 10.8.5, MacPro 4.1.
    All disks mount using primary boot disk. All disks check out as OK and I have repaired permissions.
    When I choose in the control panel the Mac boots but will always use my original boot disk.
    When I select the disk using the option key at startup, the boot process stalls with a grey screen and a spinning cursor.
    Thanks,
    Dave

    Still trying to figure this out. I erased the drive, did a format using disk util and then re-installed the system but I still cannot get the disk used as a startup drive. I also tried an external firewire drive and it won't allow me to boot from it either.
    I can choose it starting up with the option key but it just gives me a blue screen and the spinning cursor.
    If I select it in the startup pref pane it boots into my other startup drive only.

  • No Boot Disk available

    I made a boot disk of Windows 7 to install through Parallels 9, but accidentally installed it on my Mac through Boot Camp because I wasn't paying attention to the finder tabs I had open.  I did NOT go through installing Windows upon the reboot, but now whenever I restart, it goes straight to MS-DOS BOOTCAMP and reads "No Boot Disk Available."  I can Command + R, and it will take me to internet recovery.  When I go to Disk Utility, I can clearly see that my Hard Drive, and the Mac OS X Base System are still in tact and on the computer.  The layout of the screen on the left looks as such:
    251 GB APPLE SSD SD25...
          Macintosh HD
           BOOTCAMP
    disk1
        Mac OS X Base System
    My question is how do I get it so it no longer boots the MS-DOS Boot Camp and simply starts up as a Mac like it did before?  I've tried ejecting the BOOTCAMP drive, but it merely goes back to "No Boot Disk Available" when I attempt to restart.  I'd rather not lose the data on my Hard Drive and I haven't used Time Machine in a few months and would prefer to avoid that.  All of my files on the hard drive are still in tact at the moment as I've checked through browsing.

    go back into disc utility, select apple ssd, click on partition then highlight the bootcamp part of your drive, click the minus sign then click apply. after this drag the divider line down to the bottom, click apply
    then reboot, it will now start up into osx as normal.
    you are now free to reinstall windows again using bootcamp if you wish.

  • How do I create a new boot disk from an existing one?

    I have a G4 Quicksilver with internal PATA disk, running 10.4. I want to upgrade the internal disk from 40 GB to 160 GB. I have installed a second disk and can see it fine, but what I really want is to put the system on the new disk and have it be the one and only boot disk in the system. Is there a straightforward way to do this? Is a carbon copy cloner the way to go? Will that have problems with the different disk sizes? Will it handle bad blocks properly? Isn't there a way to just use drag-and-drop?
    Once I have made a copy, how do I make it the boot disk? Do I have to swap it into the PATA "master" position to do this?

    Cloning And Backup Tools
    A bootable clone is an exact copy of your drive which is capable of booting your computer. Making a copy of your computer which is capable of actually starting the computer requires special copying procedures. Some people just back up data files but if you have problems you have to reinstall all your operating system and all your applications. With a bootable clone you just start up from the backup drive and clone back everything.
    To copy files from one hard drive to another hard drive you can use:

  • Download boot disk of Solaris 2.5.1

    Hi, all.
    Where can I download a boot disk of Solaris 2.5.1?
    Thanks

    What do you mean? An ISO image of the boot CDROM? Or
    do you want to copy a boot disk from one system to
    another? I don't know about the former, my guess is
    that unless you are booting from already existing
    media from a CDROM on a system in your LAN, which is
    doable, the answer is "no".
    The latter idea, using dd to copy one disk to another
    is doable with cavaets. The disks must be of the
    same type and the system hardware configs must be
    the same. There are help documents on SunSolve about
    the details. There are many risks and even though
    you get a copy, it might fail to boot.
