Unable to Boot from Superdrive

CDs and DVDs will play fine but I can't BOOT from the superdrive. The same discs (OSX install disc and newest Diskwarrior) will PLAY in the drive. I just can't get the macbookpro to boot from them. I've tried holding down all the usual keystrokes at startup to no avail. What happens is that it chimes, waits a few seconds, then the screen goes black and it chimes again, repeating this over and over as long as any key is held down. Repaired permissions, ran Diskwarrior on it from another mac linked up with Target mode, but still I can't boot from the superdrive. I'm seeing other reports of this. Anyone find a solution?

Hmm... I haven't heard of this problem before... perhaps something went screwy in your firmware. Have you tried resetting the SMC and PRAM (the PRAM would more likely be the culprit)?

  • Though the root disk is mirrored, server is unable to boot from alternate disk (mirror disk)

    Hi PPl,
    It happened second time in a row. Though the root disk is mirrored, server is unable to boot from alternate disk (mirror disk)
    When the disk was found faulty, still unable to boot the OS from alternate disk, it says it still probe/look for other disk
    Here are the console log when I tried to boot the OS
    sc> console
    Enter #. to return to ALOM.

    In such condition left out with only two options.
    1)      Remove the faulty disk physically and boot
    (or)
    2)      Replace the faulty disk and boot it
    Any way, I can disable the faulty disk in BIOS (or) booting from cd-rom and do something to avoid it?

    You can't boot from systems earlier than that shipped with the computer. For example, early 2008 Mac Pros come with 10.5.1 and can't boot 10.5
    Also you can't boot with a DVD that was shipped with a different model Mac.

  • UCS Unable to boot from SAN

    I have some blades that I'm unable to boot from SAN.  The weird thing is I can see the LUN's and I can install ESXi 5.5 fine.  It's up until I reboot and the blades just boot to the BIOS because they don't see any disk.  When I try to change boot order, the only thing I can boot to is UEFI.  

    When you see your lun, and can install ESXi, it means, that
    - your zoning is correct
    - your lun masking / mapping is correct
    If boot fails, your boot policy is the problem ! are you sure, that the target pwwn points to the controller of the disksubsystem, that the lun nr. is correct ? we seen all kind of weird things, like cable crossed,.....

  • Bootcamp woes, unable to boot from USB and DVD drive reads all DVDs blank

    My partner and I are completely unable to install Windows using Bootcamp.  We have tried dozens of solutions on the internet.
    2011 iMac (purchased in by me and my partner 2012) reads all DVDs as blank.  We have (hilariously) another Mac, an MBP, that has the same exact problem.  You'd almost think "Superdrives" eventually just stop working or something.  So obviously we can't install Bootcamp on the iMac using a DVD.
    But what about a USB stick?  Well after modifying the plist file and writing a bootable Windows USB and trying to boot from that, we were greeted with the mysterious and apparently yet-unsolved "no bootable device" error. 
    So our iMac can't boot from USB drives or read DVDs.  We've only owned it for two years.  And this is the second Mac we've owned where the Superdrive has died.  And we don't even use DVDs more than like once a year.
    But anyway, can someone tell me what we're supposed to do if we want to install Windows aside from throwing money away to buy another Superdrive that is probably going to die again in a year?  Maybe a way to make our mac boot from our USB stick?  Something?
    Thanks.

     Should you have another drive with a MBR, use it to rule that issue out. Alternatively create a GPT on the flash drive and try to boot from it.
     What options are there for the usb controller/boot priorities/order/options? Does the laptop recognize the usb flash when already in bios setup? Should there be any form of choosing the device to boot, use that with the flash drive in the socket, then switch it with the external drive.

  • MacBook Pro won't boot from Superdrive

    I have a MacBook Pro which is around 7 Months old, I wanted to run Disk Warrior on it but the Macbook Pro wouldn't boot from the disk, tried the MAC install disk same issue.
    Holding down the C key at boot time causes the drive to spin up it gets as far as the grey screen with the apple logo then the drive stops. Tried also holding down the alt key, I can see the hard disk and DVD icons but selecting the DVD same thing happens as above.
    The superdrive seams to work fine when the machine is running just refuses to boot from it.
    Any help would be much appreciated

    Colin: Are you trying to boot from the Install/Restore DVD that was shipped with your MacBook Pro? If not, do. Your DiskWarrior DVD may not be able to boot your MBP model, and an older Snow Leopard installer DVD can't either.
    The best setup for using DiskWarrior or any other Disk utility on your MBP's internal drive is to have a bootable clone of that drive as a backup, with all your utility software installed on it just as it is on the internal drive. Then whenever you have a problem, you can boot from the other drive to repair the troubled one. No need then to boot or run the utilities from a DVD, which is tediously slow at best, even when it works perfectly.

  • Cannot boot from Superdrives on my Mac Pro!!

    Hello,
    So I tried to boot last night from my Disk Warrior CD in order to do a maintenance check.
    I hold C key but in vain after a couple of minutes I get the black screen/freeze with the message to restart holding power button.
    Today, I tried to install Leopard on my external firewire drive and when the Mac restarted I got the same result.......freeze.
    I tried both Superdrives.......same result, verified connections etc..... no dice.
    I run the latest Leopard 10.5.3 in a first edition Mac Pro Dual 2.66 with 13GB RAM and 3 hard drives.
    What bugs me is the fact that while holding or not the C key, after a couple of minuted I hear the ''click'' that you hear when you shut down the Mac Pro. It is like the Mac is shutting off but still runs for a few minutes before giving me the black screen.
    This means I cannot boot anything anymore on my Mac Pro.
    Please help me, any deas, what should I try doing.
    The 2 Superdrives are Pioneer 111D and 112D......one is master the other on cable select.
    Thank you.

    Another Surprise: I tried to boot from the original Mac Pro Install Discs, result: it crashes even faster.
    Well that's a BUMMER You've got a hardware problem somewhere and it's time for 'Hit or Miss' Tactics to find it
    First things First. Follow Theses Steps ...
    Step 1) Can you boot from the hard drive with both 'Superdrives' plug in and empty?
    If your answer is NO Goto Step 7.
    Step 2) Check the 'Superdrives' from the 'System Profiler' -> 'Hardware' -> 'ATA Bus'. Does it list BOTH Drives?
    If your answer is NO Goto Step 7.
    Step 3) Is the TOP drive 'Unit Number: 0' (Zero) and the BOTTOM drive 'Unit Number: 1'.
    If your answer is NO Goto Step 7.
    Step 4) Can you 'Mount' a CD/DVD to the 'Desktop' from both drives?
    If your answer is NO Goto Step 7.
    Step 5) Can you 'REBOOT' the 'Install DVD' from the 'Desktop'?
    If your answer is NO Goto Step 7.
    Step 6) Happy Days Are Here Again. Stop Here.
    Step 7) 'DON'T PANIC!
    Step 8) Open case and remove the 'Superdrive' bay. The 'Original' drive should be in the TOP bay with the END OF the 'Ribbon' cable plugged in to it. This 'Ribbon' cable and the 'Superdrive' should have a 'NOTCH' and can ONLY be plugged in a certain way. Set the 'Drive Select' jumper to 'Master'. Unplug the 'Ribbon' and 'Power' cable from the 'BOTTOM Superdrive'.
    Step 9) Repeat Steps 1 thru 5 and if you make it to Step 6, Repeat Step 8 using the 'BOTTOM Superdrive'.
    Step 10) Hmm, both 'Superdrives' WORK by themselves but NOT together So connect the TOP drive back as in Step 8 and connect the BOTTOM drive but change the BOTTOM drive's 'Jumper' to 'Slave'. Leave the TOP drive set to 'Master'.
    Step 11) Repeat Steps 1 thru 5 and if you DO NOT make it to Step 6 then I'll need more information from your 'Console Error Logs'.
    End Of Steps ............................................................................... .................................
    Not relevant to you problem BUT did you change your VIDEO CARD?

  • Mac mini stuck booting from Superdrive

    I have a PowerPC Mac mini and a wired Apple keyboard.
    I was testing a Linux LiveCD the other day and chose to boot up from the Superdrive through the System Preferences Pane.  The LiveCD worked, but then when I tried to restart and use the keyboard command to choose to boot from the OS on the internal HD, I realized that my keyboard isn't responsive during the startup procedure.  Therefore, I can't reset the pram either, which is what I imagine would be the easiest way to solve the problem.
    Unfortunately I don't know anyway to change the boot method from the Linux end either.
    I have various install and utility CD's from several generations of Macs, but the mini will not use any of them to boot.  I have the mini installation disc and it does not work.  Would an OS upgrade cause it to not boot from an older version's install disc?  I know the superdive (and RAM, logic board, etc.) is functional because I can run Linux of a LiveCD.
    Unfortunately I can not find any old keyboards to use at the moment, so I can't immediately test whether or not a different keyboard would be recognized.  When I looked up this problem, some people said it did and others said it didn't.
    The error I'm receiving without a LiveCD in is "No bootable device -- insert boot disk and press any key."
    Any ideas?

    Try starting up holding the mouse button.

  • Unable to boot from cloned MacOS 10.6.8 server

    Hi there,
    we've successfully restored a MacOS 10.6.8 server image to an Intel Xserve. However, there seems to be a boot cache issue. Sometimes I am unable to boot and MacOS Server won't restart. The Xserve restarts twice on the gray Apple screen. Than it's hanging on the gray Apple screen. no disk activity for minutes. I've waited 30 minutes. I had to power down the server. After that the  server boots normally. no errors in verbose mode during startup.
    I am using 3 volumes (all 3 using the same system clone). All Bay drives using the original Apple Disks. They are brand new. <29 hours.
    Resetting the NVRAM a couple of times didn't solve the issue. The booting error is reproducible. This system runs fine and it's really clean. I just installed the latest MacOS 10.6.8 combo Update
    I don't know what else I can I do? I really appreciate any help on this.

    Sorry for the delay in responding.
    Thank you, Peter. The Xserve running fine so far. We've had any boot issue.

  • Unable to boot from ODD or USB after windows 8.1 update on P850-31L

    Hi
    I just updated a P850-31L to windows 8.1 from windows 8 through the windows store.
    Before the update I was able to boot from a USB drive by pressing F12 during start up.
    After the update I was no longer able to boot from the USB drive. Selecting the USB drive by changing the boot order in BIOS setup via F2 or by pressing F12 no longer works.
    Booting from ODD is also no longer possible.
    The BIOS version is 6.70 and does not allow secure boot to be disabled. However the DVD and the USB stick I tried are signed Ubuntu 12.10 which worked prior to the upgrade. Fastboot in windows 8.1 is disabled.
    This would then appear to be a bug in the Toshiba BIOS? Or has the windows 8.1 updated the BIOS or the EFI boot partition in such a way as to override the BIOS setting? Really stuck here, doesn't seem to be much information about.
    Any thoughts or assistance would be very much appreciated!
    Thanks
    Michael
    Update: I just tried booting from the Toshiba windows 8 recovery DVD and this no longer works either.
    Message was edited by: michael_toshiba_forum

    OK I fixed this.
    Firstly it's worth noting that it is possible to to disable secure boot in the 6.70 BIOS.
    However this option is only available when the user password is not set in the security menu.
    After enabling or disabling the password a reboot is required to make the secure boot enable/disable option either available or unavailable.
    That's good I suppose as I guess it may prevent secure boot from being disabled when the machine is running. However this does not appear to have been related to this issue.
    I selected the 'reset to factory defaults' option on the exit menu.
    The machine was then able to boot from USB and DVD. The boot order was also respected.
    Perhaps the windows 8.1 upgrade somehow invisibly corrupted the BIOS settings. Or maybe it was just a stranage co-incidence that the BIOS corrupted itself during the install. Either way that factory reset fixed it.

  • Unable to boot from install disk for needed disk repair

    Hi- I need to repair my disk, but haven't been able to boot from the DVD. When I've tried (several times), I get a black screen with a long error message, ending in something like "hanging here." Any advice?
    Thanks,
    Laura

    That is a kernel panic. Kernel panics on startup from an installer disc mean one of two things usually: 1. You are using an installer disc with an OS version that is not able to boot the computer model you have. Usually the version is too early for the model; 2. There's a serious hardware problem such as a dead hard drive or motherboard problem.

  • Unable to Boot from OSX -- Get Strange Schematic

    Hello -
    A friend forgot her password on her iBook. Using this forum, we found out that she can access and change the password by booting from the OSX disk (Tiger) and opening the "Utilities" on the installer. So we inserted the disk and restarted the iBook, holding down the "C" key. To our surprise, instead of getting the usual install screen, we got what looked like a schematic of a mouse, from which we could not exit. The only thing we could do was to reboot from the hard disk. This happened numerous times. Has anyone seen this before, and does anyone have any advice? Thanks for your help.
    Shelly
    P.S.: Holding down the "Option" key at restart got us nowhere, as you are prompted to enter the password before proceeding.

    Hi, Shelly.
    You wrote: "P.S.: Holding down the "Option" key at restart got us nowhere, as you are prompted to enter the password before proceeding."While holding the "C" key is the correct way to startup from a CD, your description implies she enabled Open Firmware password protection on her Mac. See "Setting up firmware password protection in Mac OS X 10.1 or later". If you're seeing the same screen as the screen shot within that article, that may explain the problems you are having.
    There are instructions at the end of that article re: disabling the open firmware password, but they require the password. Since she doesn't know the Admin password, she's stuck in a "Catch 22" if she's enabled Open Firmware protection.
    I suggest you have her take the iBook to an Apple Authorized Service Provider.
    • If there is an Apple Retail Store in your area, I'd recommend taking it there. You may wish to call ahead to make an appointment at the Genius Bar.
    • If not, try the "Find a reseller" search here to see if there's an Apple Authorized Service Provider in your area.
    There are ways of removing Open Firmware password protection without having the password, but I'm reluctant to post them here as the same info would also be useful to someone who stole a Mac.
    Good luck!

  • Unable to boot from install disc to repair volume

    Hi
    Recently ran Onyx which told me the volume needs to be repaired (my Macbook has otherwise pretty much been running fine, perhaps a little slow on startup but no major issues). Not very clued up on using Macs sadly so did a little googling about how to go about this.
    Am I right in thinking that I definitely need to repair this even though things appear to be running alright? If so, do I do this by booting from the install disc?
    I attempted to boot my Macbook from the install disc to run a repair but I just can't seem to get this working! I put the disc in, restart the machine and hold C, but the mac seems to just boot up as normal. Am I doing this incorrectly?
    Any help is appreciated, like I say I'm pretty hopeless!

  • Unable to boot from OSX 10.6 installation DVD to run Disk Repair

    Hello all,
    I have something that is puzzling me. My MacBook Pro hasn't been giving me the best experience lately - the system just seems... slow.
    So I ran a disk permissions fix and it found some errors which I repaired. Then, I thought it might be wise to run a disk check on the System Disk as well.
    So I attempted to boot from the Mac OSX installation DVD - I tried both a "hold the "C" key" method as well as the "Set start-up disk preferences to boot from DVD" method. I even tried two different OSX installation DVD's in case one wasn't working.
    Then, I reset PRAM and I reset SMC (or at least followed the procedure as outlined by Apple - it doesn't really seem to give a strong indication of whether the process occurred or not)
    I just cannot get the system to boot from DVD. (I even tried TechTools Pro 5).
    I even let it "sit" for more than 4 hours in case it was just taking it's time.
    Can anyone think of what the deal might be? I'm REALLY wanting to run a System Disk check now!

    Ta-Da! Worked!
    You learn something new every day here! I had no idea that I couldn't boot from a standard OSX boot disk and had to use the in-box one.
    It does raise the question of which version of Disk Check I will be using - as there has been several upgraded to my OS since I bought this MacBook Pro (it has 10.6.3)
    THANKS! I really appreciate the help - now I can check the disk.

  • Equium A100 - Unable to boot from bootable disc

    Equium A100-549
    My partners son has a 2 year old Toshiba laptop that has become slow over time. I had made a backup of the system with office etc installed using Acronis. Anyway, decided to clear it off by running Acronis and the image saved. The program runs as normal and it drops down to a dos like screen ready to restore. It then sits there with the curser flashing as normal and then it locks up, and doesnt allow you to browse to the image.
    I though that this may be corrupted, so reinstalled Acronis. Made an Acronis boot disk to run the image and it ignores the disk and boots straight to the normal hard disk (IDE 0) Still no joy. Then tried the laptops restore disk. In the BIOS I specified CD device as first, and also the restore disk says place in drive and turn off.
    Then as it boots hit F12 which brings up a menu allowing you to boot from CD drive. I have done this, but it doesnt appear to look at the CD and just loads windows from the HDD. I removed the CD from system devices and rebooted. It found it and added the new device to itself and requested a reboot. Still no joy!
    Scanned with Norton but still no good. Removed Norton. The result is the same. Able to read from the CD and also write to it as well. Ran Toshibas diagnostics on the device and all appears ok with it.
    Tried to make a boot disk on flash stick, but this is ignored also, even though specified boot using other devices.
    Basically it looks like I cant get it to look at the CD before loading off the HDD.
    Would flashing the BIOS cure it? - Registry error causes this?
    Is there anywhere that I can speak to someone from Toshiba about this?
    Any info / help much appreciated

    Worked first time. I was in the middle of running a downloded version of system mechanic to see if it would find anything. Anyway, I placed the restore disk in it and pressed C on reeboot and it worked - foolishly I stopped it and tried again. It worked again. Had searched the entire net and a few forums before coming here. One post and its fixed!!!!
    A life saver, especially at christmas as I didnt want to have to buy another laptop.
    Once again thanks
    Nick
