Boot Camp forgot how to boot

Im getting "no bootable device" (or something close to this). It's flipping weird so let's start with a chain of events.
I must install WinXP via an external LaCie d2 USB/FW device. This thing can boot off Leopard install DVD just fine. It used to be able to boot off Win XP install DVD just fine too. The later capability evaporated in mid air or something else equally senseless.
1- use Boot Camp Assistant to partition HDD then start installation.
2- Windows did it's thing just fine up to the first reboot.
3- Windows can't boot allegedly because of this: (http://support.apple.com/kb/TS1722?viewlocale=en_US)
4- Start over from scratch.
5- used Boot Camp Assistant to partition HDD then start installation.
6- no can do.
It forgot how to boot off the Windows DVD. It lost the capability right there. I get either: (paraphrased) "No bootable device found. Press any key to continue" or the blank grey screen. There is no key that does anything. It's dead, Jim. I must shutdown the mac by holding the power button long enough then hold option down to select Mac. OK.
What is going on? I went as far as re-flashing the DVD firmware. It's all dandy in there. Nothing to report.
What am I supposed to do now?
Pretty please...
confusingly yours,
Andrew from Canada

OK. A bit more infos as well as a bump.
The WinXP disk show up in boot camp when connected via FW then Windows can't use FW to boot so it's pointless...
It does not show up in boot camp when connected via USB.
I know it can boot from USB because it already did that once.. This is also the official procedure for installing Windows into a Macbook Air. So there
It forgot how... or it villainy refuse to.
Come on guys, throw me a bone here. At least one of you must have a clue...

  • Boot camp often fails to boot - fix?

    Boot Camp often fails to boot at all, leaving the iMac dead at the bootloader screen. Have to force shutdown by holding down power button. Full hardware test declared the hardware 100% functional. Disk Utility and chkdsk sees nothing but fire. This is intermitent/random and it proved impossible to "force" it's occurance. It happen when it darn well please?
    First occurance goes back to late July 2011, a few days after a major thunder storm that caused pulsing power blackouts (as in, very short bursts - like turning off the power then immediately flipping it back on - too quick to actually shut the computer down). Surely, this must be the source of the issue? Right? Alas it doesn't adds up. Power supply of this house is very stable and reliable. Power fluctuations are unhearded of. It's also connected to a surge protected outlet. The system itself, in Mac or Win, is flat out stable. It does not freeze out of the blue like what a damaged power supply would cause. It only ever freeze upon choosing a partition via the boot camp interface.
    Further observation as compared to normal boot procedure: Upon selection of the Windows partition, the LED on the USB mouse turns off then back on again a short moment later. Windows loads up normally. When the crash occurs, the LED never turn back on. It's just dead right there and then.
    What's going on and what can I do to fix this? It feels like some hardware initialisation fails for some reasons. It's ough to be around the USB systems itself but what do I know anyway?
    P.S.: Please, don't mention the dreaded format and re-install. It's a 20 hours job. I'm not going there. ty

    Well, sometimes if you don't have backups, and refuse to do what you may need to....
    There are troubleshoolting tips and faqs I'm sure on the 'net.
    Starting with Windows 7 DVD for one
    Even OS X won't survive with forced (hard) shutdowns.
    If it only happens in Windows, and you were running OS X when the outage occurred...
    USB devices and cables can be hard to ID but swapping cables and stuff helps.
    As for Disk Utility, it does not look at drive sectors or files for issues.
    If you really want to scan a hard drive, use the vendor's own Linux or Windows utiilty to recertify the sectors.
    If you haven't done any deep cleaning of files, registry, even uninstall and reinstall components.
    I just did a reinstall. Partially to be a test run for when I have to install Windows 8 next week, also to clear up a problem I had, possibly a rogue web site using a rootkit to hide files and icons and programs disappeared and icons became generic. So yes I don't take it lightly, but the new install runs much much better (over two years since last install).
    AHT is not a 100% reliable at finding everything, only what it actually is designed or suppose to look for.
    A semi-loose DIMM or faulty can be enough, and not likely AHT or Memtest will find it, but Windows does tend to spot a problem with RAM during installs.

    START: run %TEMP% - Select All and send to Recycle
    Lion Recovery - show all hidden partitions and check health of all, hidden debug menu in Disk Utility can be enabled in command line
    Some partitions (GPT, EFI, System, Volume Information Block) are only tested during format where each sector does get a thorough check for errors because they can't be mapped out later. When you do chkdsk etc you only test user partition areas and not the 'entire' drive, unless doing a full initialization. And GPT requires that the VIB and also the backup VIB both be error free - in the past the backup VIB if it failed was "optional" though, it is not now.
    If you clone OS X then it is easy to move it to another drive and also to do full initialization and restore. If 3 days of your time isn't an option maybe time to invest in program(s) and methods that can backup and restore.
    Trying to find the needle in haystack that you have limped along with I guess since July (since installing Lion? maybe ?) can take 3 days probably, unless you are lucky enough to replace a mouse or cable on first step and it all goes away (hit the lottery or get hit by lightning odds)

  • How to back up Boot Camp and how to resize FAT partitions

    I suppose someone has already addressed this topic herein, but in case someone needs help I am leaving with you what I learned.
    I started with a partition sized to 18 gigs and installed Windows XP on it. Soon the drive became full after I installed software and various disc images so I can play games. I wanted to resize the partition to 28 gigs without losing my data, leaving 46 gigs on my Mac partition.
    I was not sure what would work so I chose several methods of possible restoration. The easiest was to boot to the Mac and use Disk Utility to make a Disk Image of Boot Camp. The next precaution I took was to back up my settings with the Windows Files and Settings Wizard. Lastly, I booted to Mac and turned on viewing of hidden files. Then I copied all the files off the Windows XP partition onto an external drive. I also tried Acronis True Image while in Windows but it was not compatible.
    I also discovered a free program called Winclone (http://www.tuaw.com) that makes an image of the Windows partition and restores it for you, much like Disk Utility works.
    In OSX, I ran Boot Camp Assistant again to rejoin the partitions. Then I ran it again to partition the new drive to 28 gigs.
    The first thing I tried to do was to use Winclone to restore the Winclone image. That failed with errors. Then I tried to use Disk Utility to restore the drive and Disk Utility would not allow me to restore the disk image onto the drive. I am not sure why Apple is so unsupportive of implementing their Disk Imaging technology within the context of their own self-created Boot Camp technology.
    Anyway, the last thing I could try was to copy the files back onto the new partition or to give up and reinstall Windows and use Files and Settings Transfer Wizard to restore my Windows settings.
    After partitioning the drive with Boot Camp Assistant, I copied the files over and rebooted. Windows said there was an unsupported drive. Then I realized that I missed a step in the installation instructions provided by Apple for Boot Camp. I forgot to format the drive again using the Windows XP install CD, that the Apple says is necessary.
    So I booted up the Windows cd and erased the Boot Camp partition and made it a FAT drive so that I would be able to copy my files over to it from OSX, which I would not have been able to do had the drive been formatted as NTFS.
    As XP started to install its software, and it started to copy files from the cd, I pressed the power button to shut down the Mac. (Do this at your own risk. I am warning you that this could damage your computer, so do NOT try this if you feel uneasy about it.)
    I booted into OSX. Then I trashed the few files that Windows had started to install on the Boot Camp drive. Then I copied all my backup files back onto the partition.
    Here is a widget that will allow you to view hidden files in OSX: http://www.apple.com/downloads/dashboard/developer/hiddenfiles.html
    I rebooted the Mac and held down the Option key while restarting. When the Mac and Windows drives appeared at the startup screen, I selected Windows, which booted up successfully. It then recognized the partitioned drive as new hardware and required me to restart, which I did.
    I wanted to convert my drive from a FAT drive to a NTFS-formatted drive.
    This is how I did that:
    http://technet.microsoft.com/en-us/library/bb456984(TechNet.10).aspx
    After converting Boot Camp to NTFS file system I noticed an immediate speed increase in Windows XP. I
    In conclusion, Disk Utility is a good method of backing up your partition, as it allows you to use a password to make a disk image of your drive. It also allows you to copy the files off the disk image onto the Windows partition. But it would be a lot simpler if Apple allowed them to use Disk Utility to restore the whole image back onto Boot Camp.
    Other methodologies I did not get to explore because I am happy with my results:

  • Can OS X drives be protected from boot camp, and how to backup?

    1. If I create a boot camp partition on my main drive, can I somehow protect my other drives and OS X partitions (and main drive OS X partition) from any possible tampering from a Win7 boot where I'm running software that could be infected or problematic?
    2. How will I back up (and restore)? I've been using Carbon Copy to clone my drives, but unsure if that will also clone a Boot Camp partition?

  • Reformat Disk to Run Boot Camp.  How?

    I am trying to load boot camp and partition my hard drive but everytime I set it to partition I get this warning:
    "The disk cannot be partitioned because some files cannot be moved.
    Back up the disk and use Disk Utility to format it as a single Mac OS Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again."
    I have tried to do this by using the Erase function in Disk Utility but the options to select format are dulled so I can't click them. I have repaired the Disk permitions and have tried to repair the disk but this options is also dulled and can't be selected. I have tried doing this in both Safe Mode and in normal mode But non of this works.
    Looking on the discussion board it has been suggested that you need to restart the computer with the installer DVD and doing that way. I don't know if I've missed something or if I just have a mental black because I haven't had to do this in a while, but how do you do this reformat?
    Any help would be appreciated
    Kim

    That's the thing I've restarted the computer with the install disk and I don't get any options to choose languages. All that happens is that the file for the install disk opens as though I were to install Lepard. I've done this and opened disk utility but Volume Format is still dulled in the Erase tab.
    Is this what you meant? Or do I have to restart while holding down a key or something? I'm really sorry to sound neady but everything I try is not working would you be able to make the instructions step by step and very specific.

  • Failed boot camp install - how to remove windows partition?

    Hi There,
    After a failed boot camp install, boot camp no longer sees (or can remove) a windows partition - Disk Utility can't seem to remove it and if I use:
    $ diskutil list
    It shows up as partition 5 "Microsoft Reserved"
    I also have a portion of free space that I can't seem to incorporate back into the main OSX partition - how do I remove the windows partition and make the drive a single OSX drive again?
    Any help would be much appreciated
    Cheers

    - New Mac Pro
    - Installing onto internal 1 TB SSD
    - 10.9.3
    - Windows 8.1

    Just incase others have this issue, this wasn't caused by using Disk Utility (Disk Utility couldn't remove the partition anyway) it was caused by repeatedly trying to format the Boot Camp partition using the Windows installer when Windows refused to install.
    The solution is an Apple tech note (I can no longer find it sorry) that sates that no other hard drives besides the internal HD and the Windows USB flash drive can be connected while installing windows.

  • To boot camp or not to boot camp

    I have an older Macbookpro with a 200GB hd (I thought I had 160GB, but it's showing 199.71), with 150 GB currently free. I just upgraded to snoleopard, wiped my internal HD clean, loaded fcstudio2, and have massive backup available so I don't clutter this machine.
    My intent is to make this older laptop the field tool for data wrangling; loading and transferring HD video from P2 CARDS, CF cards, etc. I know one person in particular that will want big video files transferred onto his PC formatted drives. I will either need a pc laptop for that, or I'll need to boot camp this macbookpro. I'd prefer to bootcamp it for simplicity sake, but I worry that my machine is old, and I need superior performance in the field with what I have, and I don't want to bog this laptop any more than it already is. Currently, QT is having a real hard time with my HD H.264 files- they stutter so much in QT that I can't check the files before I transfer them to the client. I won't have time in the field to convert to ProRes 442(?) in order to verify that the video is capturing effectively. I've downloaded a VLC player, which seems to handle the H.264 better, but the fact that stuff is already bogging down makes me wonder whether I should stress this machine out any more than it already is.
    Do any of you have experience with bootcamp on an older macbookpro, and working with massive HD video files? I don't need to edit much, or do much else, I just want this to be an effective, flexible field tool for downloading and transferring (and verifying) video files in both pc and apple formats.
    So, should I boot camp this puppy or not?
    And if y'all think that bootcamp won't bog this machine down too much, how do I find the date this machine was built so I can figure out which pc OS is compatible?
    Thanks!
    John

    If your computer is "bogged down" now, it will be "bogged down" when doing the same thing in Windows. Bootcamp uses your computer's hardware in the same way your OSX uses your computer's hardware. Just adding Bootcamp in itself won't bog down your computer any more than booting into OSX does. OSX and Windows in Bootcamp don't run at the same time. Whichever OS you boot into will use all your computer's resources.
    So if your hardware is not up to task when doing video in OSX it won't be up to task when doing video in Windows (Bootcamp).

  • Boot camp services setup failed - Boot camp 3.3 update

    Running Windows 7 Ultimate on a 2008 iMac with boot camp 3.2. When running apple update to install boot camp 3.3, after a reboot I get the following message from the installer: Boot Camp Services Setup Failed.
    Sorry, After I posted I found the answer. I also had a logmein display driver and once uninstalled boot camp 3.3 installed just fine.

    The BC Service is installed for any individual login (whether local or domain-based), which happens only the first time. The BC Driver Installer has no option to install the services for 'All Users'. This is expected behavior.

  • I can't create a USB booteable Windows in Boot Camp Mavericks that actually boots

    Hi everyone... I have an issue that is apparently very common and yet I haven't found a working solution... I'm trying to install windows 7 using boot camp on my iMac 8,1 it is running Mavericks... I've got as far as creating the windows USB but after boot camp attempts to restart the computer I get that "no bootable device -- insert boot disk and press any key" message. My DVD unit is not working so I decided to try with the USB option but I'm stuck... I've tried using different (very different) pen drives (brand and sizes) but I always get this. I have also tried holding the alt/option key when I turn the computer on but it does never shows the USB, I've tried with different .iso files 32 and 64 bits, original and "questionable"... I hope you guys have a working solution for this. Thanks in advance, have a nice day.

    Windows will not boot from USB if the Mac has an internal optical drive. This is something that Microsoft implemented.

  • Cloned boot camp partition won't boot

  • Made a new partition on Macintosh HD, Boot Camp will no longer boot.

    Specs:
    MacBook Air 2013
    8GB RAM
    i7
    512GB SSD
    Hello all, looking for some assistance.
    My HD is formatted to 400GB of OSX and 80GB of Boot Camp. I stupidly made the mistake of adding a new partition out of the large amount of free space I have on the OSX partition, to format the new partition for Windows. This made Boot Camp no longer boot. On the Disk select screen after holding Option on boot, my Boot Camp partition is not visible. I can see everything on the partition on OSX, however.
    To try and fix this, I deleted the new partition and tried to reduce the hard drive back to the original two partitions. However, I cannot extend the OSX partition to fill in the new free space. So now I have a Boot Camp partition, my OSX partition, and 20GB of unused, free space that I cannot use or put back into the original partition.
    I asked AppleCare live chat for any assistance, they suggested that I use "Erase free space" in Disk Utility to use the space again. However, the option is greyed out on both the drive and the Macintosh HD partition.
    After a bit of googling I saw a suggestion of making a USB Recovery drive to get the space back through Disk Utility that way. This still did not work; the results were the same, unable to add the space back to the original partition, and "Erase free space" is still greyed out.
    Using BootChamp (notice the H, this is an app that allows you to restart and boot directly into Boot Camp through OSX), I get a DOS screen saying "No bootable device – insert boot disk and press any key". I cannot get this screen any other way.
    I have repaired and verified the disk and its permissions, to no avail.
    I cannot think of anything else to do short of formatting the entire drive but this is obviously less than preferable. I additionally do not have a backup of the BootCamp partition (as it is not accessible), even though everything is visible on the partition through OSX.
    So, in summary, I added a new partition to my HD and now Boot Camp will not boot. Any ideas?

    "rEFIt is an alternative bootloader for your Mac that's a lot more forgiving. If you don't think investing in iPartition is worth it, I'd give this a shot:
    In rEFIt, do not boot: go to the EFI shell, and type "gptsync". This will tell you that the partition table is out of sync, and will offer to sync it for you. Say "yes", naturally. Now reboot and all systems should be go!"
    This worked.

  • Do I Need to Use Boot Camp Assistant to Make Boot Camp Bootable, to Make It Work?

    Hi. Could I just use a third-party program instead to partition my iMac drive and then restore the image of my Boot Camp using a third-party image restoring app and then install the Boot Camp drivers from Apple (I hope they update them soon)? Or everything still has to go through Boot Camp Assistant to make Windows 8 Pro boot and work properly (I use Windows for gaming, benchmarks and diagnostics)?
    Thank you in advance.
    God bless.

    One thing is the Boot Camp Assistant version, and another thing is the Boot Camp drivers version. You have told us your Boot Camp Assistant version (OS X Mountain Lion has got Boot Camp Assistant 5), but this doesn't mean that you have to use the Boot Camp 5 drivers.
    As you want to use a 32-bit operating system, you have to use the Boot Camp 4 drivers (Boot Camp 5 only supports 64-bit Windows 7 and 8). In order to download the correct Boot Camp 4 drivers version for your computer, download Boot Camp Support Software from the Apple site > http://support.apple.com/downloads Just search the Boot Camp 4 software which is compatible with your computer, and install them after installing Windows.
    If you need all the steps to install Windows on the Mac, print this PDF > http://manuals.info.apple.com/en_US/boot_camp_install-setup_10.8.pdf
