Enormous frustration over Boot Camp installation of Win 7 64bit

Please help, I am totally frustrated after days and days of trying to install windows 7 on my iMac 11,2  (21.5”, i3, mid 2010).
So, my super drive is dead and currently I don’t have an option to replace it. I recently upgraded my OS to 10.8.3. Because my iMac is having an optical drive, in Boot Camp Assistant there was a grayed out option to create bootable USB drive. I edited info.plist file, so I finally got that option right, but no metter what, I can’t boot Windows 7 64bit installation. I’ve tried numerous ways to do that. I tried standard create USB in Boot Camp assistant, I’ve tried Windows download DVD/USB tool, I’ve tried Rufus, BootInIc, I’ve tried more than 10 different Kingston/Verbatim/No name/Corsair/Patriot USB sticks, I’ve tried several WD/Toshiba/Transcend/Silicon Power external drives formatted both fat32 and NTFS (when formatting external drive in fat32, I was reducing the external drive’s size with diskpart/create partition primary commands in windows. EVERY SINGLE TIME after partitioning the hard drive in Boot Camp Assistant, my computer restarts and there was a “No bootable device” screen. I’ve than tried Refit, there I get an option to boot from external drives/usb sticks, but than after clicking on a boot windows from USB I also get the “no bootable device” screen. I’ve tried naming sticks different (because some people are saying that it must be named WININSTALL, but without any success)
Thank you very very much in advance, currently I don’t know what to do next.

If your iMac came with an internal optical drive you can not use the USB port to install Windows. Get the optical drive fixed.

    MacBook Pro 8,1 – Intel Core i5 – 2.23 GHz (early 2011) New with OSX 10.6 – current on all updates.
    I successfully installed rEFit. I used Boot Camp to install Win 7.  All was great.
    Then installed debian 6.  Somehow after the debian install and restart (I know this sounds crazy) but I am now reduced to Win 7 only. rEFit is not present when rebooting nor is OSX or debian. Further, I am unable to force the install DVD to launch when rebooting, by holding C, D or F8.  The Option key brings me to the grey screen with a padlock. I have attempted the root and local pw- no go. Restart holding D takes me to the windows boot manager. I have attempted several options within the Advanced Options; including – Repair Your computer, safe mode and “last known good config,” All of which did nothing.
    I can see all my OSX files within win7. I tried to install the OSX within windows. Ya right, that did nothing..
    I only desire to get back to OSX...
    What are my options??

    Yes, you royally hosed up your machine.
    You should first try to get your files off, any way you can to a external drive.
    Your going to need to hold c and boot from the disk that came with your computer and a couple of screens in under the menu is a option for Disk Utility.
    Select your drive and Erase with Security Option Zero, format the drive HFS+ Journaled and when that's finished (about a hour or so) then quit and install OS X from the installer.
    I hope this works, but I suspect it won't. Others have hosed their machines trying to use a Linux disk without proper partition formatting too.
    Another option might be to use another Mac to c boot off the Snow Leopard disk and install OS X onto a external drive, take that to the problem Mac and try holding option and booting off of it to erase your internal drive.
    You could replace the drive.

    Is this holding option while booting?
    There was someone else around here who hosed their Mac with a Linux disk too. Try to find it.

  • Boot Camp Setup for Win Vista/7: "The short-short version"

    This tip's dedicated to all those who want a detailed instruction manual, but for whatever reason don't want to read through Apple's Boot Camp Installation and Setup Guide @ http://www.apple.com/support/bootcamp .  But before I copy this from the thread that started it, let's make clear what shouldn't work and thus should be avoided:
    Per the Boot Camp Win 7 FAQ from Apple, no 2006 model will be supported for installation or upgrade, though many units would in fact meet the bare hardware requirements for 7.  Upgrading from Vista might work better, but there's absolutely no guarantee that all features will work.  Do not post a question asking for support of the unsupported.
    For reasons known only to Apple, the 2007 models are not considered "64-bit pure" and as such, Apple will not allow 64-bit Windows on 2007 units.  Empirical evidence from around the Web--even here-- may suggest the contrary, but again, this is unsupported.
    The 2010 lines are the last to support Vista in any form or fashion, excepting the late '10 Air, which falls to the final point...
    PLEASE, PLEASE, PLEASE, FOR THE LOVE OF ALL THINGS SACRED: Do not post questions asking to support any version of Windows other than 7 on the 2011 lines thus far, or anything in future.  The only way to get Vista or prior on these things is through a VM emulator! We can help you set one up.
    AHEM!  Now, on to the guide:
    Make sure you have everything square on the Mac side first with software and firmware updates.  Launch Software Update and run it until nothing is left to update.
    Now, it's on to the Boot Camp Assistant.  Launch this from/Applications/Utilities, and follow the prompts.  For the 2011 models, you'll get the chance to burn a dedicated software CD for the first time since the beta.  Use this in place of the install discs below.
    Move your Windows partition slice so that you have, say, 50 GB for Windows.  This can actually be any size above 40 GB.  Windows 7 x86 needs about 20 GB during installation alone, though actual used space is much less once it's installed.  The same applies to the x64 version, but let's give that one, say, 60 GB or more as some files may be duplicated for the two different "architectures" in that version to run concurrently.  As to which architecture to choose, you need the 32-bit version for the '07's or if you have a nest of old hardware or software laying about; go with the 64-bit version if you have a newer Mac with scads of RAM or just want better performance out of what you have.
    When you've apportioned your hard disk space, get your Windows DVD out and let Boot Camp start it.  If you missed this step, you can insert the DVD later and hold the C key as the Mac starts.
    If your unit shipped with OS X 10.6, have your Install Discs handy.  If you upgraded from 10.5, then the 10.6 upgrade DVD will do.  We'll soon use either one.
    During the Windows Setup process, you'll be asked to do an upgrade or custom install.  Choose Custom, which will take you to a partitioning screen.
    On the partitioning screen,you must click Advanced and then select the volume tagged BOOTCAMP. 
    You will then have to click Format while the BOOTCAMP volume is highlighted.    Click Yes to confirm.  Wait for about a minute while NTFS structures are laid on this volume, and then hit Next.
    Let the Setup program finish out the install, then add your Product Key and set up your Windows account. (Vista puts the Product Key prompt at Step 6 instead)
    Since the soft-eject key at the top of your keyboard won't have a driver yet, you'll be removing the Windows disc as follows: 
    Click Start, Computer.
    Select the DVD icon. 
    Click Eject in the upper toolbar of the Computer window.
    Now, insert your Mac install disc (or 10.6 upgrade) and run the Setup file when prompted by AutoPlay.  This will start Boot Camp 3.0.  Follow the wizard through (there's only one option for Apple Software Update, so take it as you hit Next several times.).
    From here, you may restart in Mac OS at points in this walkthrough.  To avoid this, hold the Option key to bring up a boot menu, then click Windows.
    (TIP: You'll be working in Windows for a while, so you can hold Control as you click Windows in the boot menu, to make it "persistent". You can also switch back to Mac OS by the same when you are done.).
    Back in Windows again, run Apple Software Update to pick up any and all fixes for your new Boot Camp package.  You could be doing this 2-3 times.  Repeat until no required updates remain.
    Do the same for Windows Update as well. The tip above will save a finger or three.
    Once all updates are in, add your favorite software, and you're done.
    Good luck installing Windows!

  • Boot Camp Installation: Definition of, and insights into "External Drives"?

    I'm recovering from a logic board failure. One casualty was that I lost my prior Boot Camp installation of Windows on my main internal hard drive. :-( Wondering if I can install Windows anywhere other than the main internal hard drive so I can maximize space on my OSX main internal drive?
    From what I've gathered, installing Windows 7 Boot Camp is very difficult (and perhaps impossible?) on an external hard drive. However, what's not entirely clear is what constitutes an "external drive".
    Questions:
    1. Can I install a bootable installation of Windows 7 using Boot Camp (obviously not running OSX in this scenario) on either the:
         A) Data Doubler 7,200 drive
    or
         B) Express Card 34 SSD drive
    2. Can I also install Parallels (on the main internal OSX drive), then while in OSX launch (a much slower) Windows from location A or B?
    Context:
    1.  On a late 2011 MBP 17' (version 8,3), I've replaced the stock hard drive (7,200 rpm) with a much faster OWC SSD Drive. (Awesome upgrade, btw!)
    2. The internal apple dvd device was removed and the stock hard drive was inserted in this location using OWC Data Doubler. (Also, very nice.) An extra challenge here is that the dvd drive is now an external device. I have a Windows 7 install disc, but I'm not sure if it will be recognized during the installation process?
    3. This model MBP has an ExpressCard 34 slot, for which I can buy an SSD drive. Never used this slot and have read mixed reports on boot ability.
    Any and all insights greatly appreciated!

    Many thanks for the helpful response, Loner T.  I think I've got it. To install Windows through BCA on the Optibay drive, I temporarily move it to the main SATA bay. I can then temporarily put the DVD drive back in the Optibay. So here's a question: In doing this, I would no longer have an OSX boot drive (since I'm temporarily removing my OSX boot SSD). It's been a while since I used BCA, so my memory is fuzzy (sorry), but does the BCA process need a working OSX install on the drive in the SATA bay?
    The SSD with OSX boot is normally (for your specific scenario) kept in an external enclosure (USB/FW/TB) to boot from and run BC and partition the disk in the main SATA bay.
    You mention that modifying the BC info.plist causes issues. I lost you a little here. Using the method you describe (move the Optibay drive to the SATA location, run BCA to install Windows, then move the drive back to the Optibay location), does the BC info.plist need to be modified or not?  If yes, a few more details would be welcomed. If not, what prompted this thought?
    If you have a functional Optical drive and the designated Windows-to-be in the proper bays, the BC info.plist modifications are unnecessary, and can cause other grief, and are best avoided.
    Thanks also for the bleeptobleep post. It says to use a USB3/Thunderbolt external drive (which I do have); however, my MBP (version 8,3) only has USB2 ports. I realize that a USB2 port will read a USB3 external drive, but was wondering if this limitation is a deal breaker for a bootable Windows system, or if it just means that things will be really, really, tragically slow due to low transfer rates. Any idea on this aspect?
    USB3 can cause problems for Windows 7 installer, bot not as many issues for Windows 8+. It is better to stick to USB2, but you are correct it will be slow. OSX can boot and will use RAM much more aggressively, unless it has to go back to the USB (2/3) when things may give you a beach ball. Windows 7/8 are less friendly for caching the whole OS and applications in RAM, and may be slower. A TB connection is much faster (TB2 even better).
    BTW: Bummer that the ExpressCard slot can't work for booting into Windows. That would be pretty slick. I've seen some older posts by folks who were once able to do this, but seemingly only with early versions of OSX. Apparently newer OSX versions either did away with this feature, or seriously complicated the process. Would love to find a workaround if one exists.
    You can test it, but may have some issues finding storage for ECards.

  • Help evaluating complex boot camp installation

    I need to do a bit tricky boot camp installation, and would appreciate if somebody could evaluate before hands whether the plan outlined below should work, or if i should try some different approach:
    Current setup is Tiger with two OS X partitions (16gb root, rest mounted under /Users)
    Desired setup is Tiger with two OS X partitions, AND a Windows Vista partition.
    Plan is:
    - Make disk image of the current (Tiger) root partition, and backup of /Users
    - Boot from install DVD, re-partition the internal disk to single partition, restore the disk image to the single partition
    - Upgrade to Leopard
    - Install Boot Camp and Windows Vista
    - Use 'diskutility resizeVolume' to split the Leopard partition to two
    - Overwrite the first partition with the original Tiger disk image
    - Restore Data to the second partition
    How about? Will Boot Camp continue to operate when i overwrite Leopard system with the Tiger disk image, and when i split the single partition to two pieces? Or is there some other recommended way for doing this?
    Thanks,
    Henri Karapuu

    'diskutility resizeVolume' should had naturally been 'disktool'. Also sorry about the layout, for some reason single dashes in front of each line got eaten.

  • A few questions about Boot Camp: installation, performance, which Win OS?

    Hello.
    I am planning on getting a windows OS. My main motives for this are because I would like to get some PC only games (I've been eyeing that Fallout 3 Game of the Year Edition that is soon to come out) and because there is a good chance that I will need some PC only programs for my college work. I just had a few questions before I did anything. Note: I am running 10.5.8 now but getting 10.6 soon.
    1. According to wikipedia: "Its functionality relies on BIOS emulation through EFI and a partition table information synchronization mechanism between GPT and MBR combined". The only word I understood of that sentence was "emulation." I know that emulation software significantly reduces performance. Is this true for boot camp? (say i were to get the exact same game for both mac and windows and set them to the exact same performance settings, when playing on windows, would there be more lag than on OS X?)
    2. Which Windows OS should I get? Since I am just going to be using Boot Camp to run games and a few other programs, would XP be the best to get to optimize the application's performance (as opposed to Win 7)?
    3. How complex is installation? I am a decent Mac techie, but this is my first time with boot camp, and I am a Windows noobie.
    4. There seems to be a lot of talk about partitions. What exactly is a partition? I have some theories, but want to know for sure.

  • Can't install Boot Camp Drivers on Win 7 (Fusion)

    I'm really sorry - I know this has been asked a thousand times before, but every response I've found so far either didn't work for me or it was too technical for my limited knowledge. I'm on the verge of tears after having tried to solve the problem for over 5 hours. It's past 2am here in Australia and I really should go to sleep but this is driving me insane!
    Yesterday I installed Windows 7 on my Macbook Air (13" 2011 model, running Mountain Lion) using Fusion 5. I need to run Windows-only applications for work, which also requires accents (I am a translator).
    As I didn't go about it using Boot Camp, I tried following this step-by-step to get my keyboard working properly: http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&d ocTypeID=DT_KB_1_1&externalId=1005578
    No luck.
    I downloaded the drivers using Boot Camp onto a USB stick formated as MS-DOS (FAT). I tried running setup.exe but keep getting the horrible "This version of Boot Camp is not intended for this computer model" no matter what (tried the "Troubleshoot compatibility" trick, tried re-formatting my stick and downloading the drivers again... nothing worked).
    I then tried to run AppleKeyboardInstaller64.exe only and got an installation wizard. Windows says installation is complete, although I can't see this driver on the program list (should I?) - I can only it see it when I go to Control Panel\Programs\Programs and Features (from there I get the option to uninstall it but not to open it). HOWEVER, when I attempt to add an Apple keyboard, I can't see any, under any language.
    I have tried alternative solutions like building my own keyboard layout but that didn't work either because I can't make the accent functions work in order to set up the layout!
    Adding a foreign keyboard layout to Windows just gave me a very random set of strokes that will drive me insane if I have to type them regularly.
    I just want to be able to use the standard strokes for accents on both OS:
    Alt+e for á
    Alt+i for ^
    Alt+c for ç
    Alt+` for à
    Alt+n for ~
    Can any good soul help me? I'm not an IT person, just someone who used to be married to her Mac (a very happy marriage) and who is now about to throw the laptop out of a window. Please HELP!!!

    That article was also my starting point and I have followed those steps again and again and again. I haven't slept, I haven't done anything other then try to make it work for more hours than I can count. I came here for help because that solution is not working for me.
    The region and keyboard type settings simply don't have the Apple keyboard layout listed. As I said, someone on the Fusion forum tried to follow the article's instructions too and he managed to get it working because he COULD run setup.exe (Boot Camp Drivers) on his machine, and I CAN'T. Yes, it is all explained in that article... but the drivers WON'T INSTALL, I get an error message saying "This version of Boot Camp is not intended for this computer model".
    First you said it wasn't physically possible for me to install the drivers, then you said I should just follow the article. Well, the article clearly says "Install the Boot Camp Windows device drivers in the virtual machine" which you just said couldn't be done! I want to cry. I should have just bought a second laptop, this is too painful.

  • Can I install Boot Camp 5 from Win 8?

    I have a late 2011 Mac Pro tower running Windows 8 and Boot Camp 4. I have had Windows 8 ever since it came out, that means that I upgraded to Windows 8 with the last version of Boot Camp 4 (with no issues BTW). Now there is Boot Camp 5,  and I want to upgrade my Mac Pro to Boot Camp 5, but the installer of version 5 tells me that I need Windows 7 to install Boot Camp 5. I already have installed Windows 8.
    How can I upgrade to Boot Camp 5 from Windows 8 in my Mac Pro without going back to Win 7 or by formatting my drive?
    Any help would be appreciated.
    Thanks!!!

    Thank youn for the reply...
    This is what I get when I try to install from the USB drive...

  • Boot Camp 2.1 & Win XP Service Pack 3

    Greetings!
    I recently upgraded this MacBook with a 200GB hard drive, and installed OS X 10.5. I then created the standard, 32GB partition to install Windows XP Pro. Everything was fine, until I tried to update Boot Camp to 2.1. Multiple attempts have failed, with no real reason why. Apple Software Update tells me that the update couldn't be installed, so please choose the Download Only option, and install manually. I did so, but when I run the file, it goes through the Windows Installer configuration, then immediately says that "The installer encountered errors before Boot Camp could be configured." I also fetched the package from Apple's download page, and got the same result. I am somewhat at a loss, so any assistance would be greatly appreciated.
    The other issue is with XP SP3. When I attempt to install it, either from Windows Update, or from the complete download package, it informs me that there is insufficient for the uninstall information, which requires at least 4 MB of additional space. I almost laughed when I read that the first time, since there were over 20GB of free space at the time. Some quick google-searches haven't yielded anything particularly informative, so I figured this would be the quickest place to get some answers. Thank you in advance!

    I ran into a similar situation. I found the solution next door at:
    http://discussions.apple.com/thread.jspa?threadID=1682935&tstart=0
    This appears to be a problem on several different models.
    My graphics card was correctly identified on XP SP3, but it had an old device driver. I followed the instructions to install an up to date driver.
    I had a 10.4 iMac running XP SP2 via BootCamp 1.x for more than two years.
    Upgraded to 10.5.8, and BC 2.1. Then updated XP SP2 ==> SP3.
    BSOD every 10 minutes.
    Most general solution to correct problem:
    1. Restart into OS X.
    2. Run System Profiler - write down the name of your graphics card. (Mine was misspelled -- "AYI" instead of "ATI"!)
    3. Follow instructions at above link. (You might already have .Net 2.0 -- I did.)
    Problem solved.

  • Two Boot Camps installs on the same Mac Pro?

    Is it possible to install two Boot Camps on two different internal drives on a Mac Pro? Can I rename the Boot Camps disks to, say, BOOTCAMPXP and BOOTCAMP7? Will this confuse the startup disk system preference in OS X or the Boot Camp control panel in XP and Windows 7?
    I would really appreciate any help here.
    Steve

    Hi,
    first: be sure to have/make a backup of what you have now.
    second: have a look at the instructions here http://www.harbar.net/articles/mbptb.aspx
    The order you need to do the installation/partition is this:
    Mac OSX, Win XP (instead of Vista), W7 (instead of Windows 2008 server) (as used in the linked article).
    Good luck

  • Boot Camp install of Win 7 TO USB external drive?

    Hi,
    I recently bought a 32 GB USB thumb drive. I was able to install a full copy of SL on the drive and use it to boot several different Macs in my household -- it's a little slow, but it works fine. The procedure was dead simple -- format the drive and away you go.
    I cannot, for the life of me, figure out how to do the same thing with Boot Camp/Windows, i.e. install a copy of Windows on the USB thumb drive such that it will boot and run on a Mac.
    I read somewhere else here that it isn't possible -- that Boot Camp can only run on an internal drive. I guess my question is: if all my Macs can install and boot OSX from an external USB drive, why isn't it possible to the same with Windows?
    (As I type this it occurs that I didn't try booting the Mac from the USB drive, partitioning the thumb drive in Boot Camp and installing Windows from there. It would be pretty slow going, but maybe that's a solution?)
    Thanks for any/all illumination!

    From my days using ThinkPads (long, long ago) I remember doing flash updates to the BIOS. The updates came from IBM, not Microsoft (so I assume the BIOS was hardware-based, not software (i.e. Windows o/s) based.
    That suggests (to me, anyway!) that something in the Mac motherboard prevents installing Windows on an external drive (but allows OSX to be so-installed).
    I've also read the Macs use "open firmware" instead of BIOS and that open firmware is, to some degree, programmable (as in programmable to allow Win to boot from a USB drive).
    Am I on the right track or am I completely, totally, wrong?! (I'm 'way over my head here).

  • Issue with boot camp installation

    Hi, i have som problem with installing boot camp. I get an error message in the Windows installation guide that my superdrive are missing the correct drivers. I have tried to eject the Windows disk to insert my Snow Leopard recovery disk, but i cant eject it during the set up.
    Any suggestions?

    First post so sorry if this is not in the right place but wanted to post this so it might help someone.  I have installed boot camp on macbook air and had no issues.  We were trying to install Boot Camp on new macbook pro with 10.7.4 and boot camp 4.0.4.  We could not get it to burn the windows support files.  It would download the windows support files but fail to burn every time with no option to save the file.  I forget the exact verbage.  After searching all over the web  / forums, etc we tried several times and it would fail every time.  We finally thought that maybe it was too large of a download to fit on a CD so we tried it with a DVD and BINGO!!  I feel stupid but seriously!!!!  It couldn't just tell us that the target was not large enough.  Just wanted to post for others.  Thanks

  • MacBook Pro 13" Late 2011 Experiencing Significant Slow Down After Boot Camp Installation

         Okay, so today, after installing Windows 7 on my MacBook Pro via Bootcamp Assistant, I experienced significant performance slow down (fans going at full blast, applications opening after extended periods of time, keystrokes not being registered) when I returned to my OS X partition/second hard drive. I have dual hard drives, one of them being a Samsung 256 GB SSD with OS X Mavericks and the other being my original 500 GB HDD, divided into a 250 GB OS X Mavericks partition and a 250 GB Windows partition. I have the SSD set as my startup disk and I have it located in the main HDD bay. I moved the old HDD into a caddy and placed it where the optical drive normally should be.
          After multiple failed attempts to install Windows via USB and Bootcamp Assistant, I decided to reinstall my optical drive and use a Windows installation disk. This attempt proved successful, and I was able to install Windows 7 onto the 250 GB partition I had created for it on the 500 GB HDD. After completing basic setup of Windows, I removed the optical disk drive and reinstalled the SSD and the HDD into their original spots (SSD in the main HDD bay, HDD in the caddy where the optical drive normally is).
         After completing this tedious process, I booted my Mac back up using the SSD. However, I noticed something was wrong when the login screen, apps, and nearly everything else on my desktop had slowed to crawl. I decided to check my Activity Monitor to see what the problem might be. Activity Monitor told me that the task "kernel_task" was taking up anywhere from 200-600% of my CPU, which explained the slowdown in performance. I looked around to see if there were others with the same problem as me, and I found that Spotlight Indexing might be an issue, with a potential remedy being move my Bootcamp Partition into the Privacy section of Spotlight under System Preferences. After doing that, I experienced no increase in performance and everything was still going very slowly.
         The next step I took was to see if booting into Safe Mode would help the issue. After booting into Safe Mode on my SSD, I noticed that things were back to their normal speeds, with applications opening at the speed they should be and keystrokes being registered instantaneously. However, the fans were still going and had not shut off once booting into Safe Mode. In addition, I checked Activity Monitor and the "kernel_task" in question was no longer taking up massive amounts of the CPU.
         At this point, I don't know what to do and I need help in restoring my Mac to original speeds. I may end up deleting my Boot Camp partition as a last measure if all else fails, seeing as I installed Windows in the first place for running a few programs and games that I can live without. However, I'd prefer to not have things come to that and fix things before deleting the Boot Camp Partition. I've heard that if everything runs normally in Safe Mode, then the issue is third-party software. Is this true?
         Any help would be greatly appreciated as I am writing this from the MacBook in question in Safe Mode because it's essentially useless in normal SSD operation.

    1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
    Don't be put off merely by the seeming complexity of these instructions. The process is much less complicated than the description. You do harder tasks with the computer all the time.
    2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
    There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the behest of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
    Here's a summary of what you need to do, if you choose to proceed:
    Copy a line of text in this window to the Clipboard.
    Paste into the window of another application.
    Wait for the test to run. It usually takes a few minutes.
    Paste the results, which will have been copied automatically, back into a reply on this page.
    The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
    4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
    5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
    6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
    Triple-click anywhere in the line of text below on this page to select it:

    Copy the selected text to the Clipboard by pressing the key combination command-C.
    7. Launch the built-in Terminal application in any of the following ways:
    Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
    8. If you see an error message in the Terminal window such as "Syntax error" or "Event not found," enter
    exec bash
    and press return. Then paste the script again.
    9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
    If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
    10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
    [Process completed]
    to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
    11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
    At the top of the results, there will be a line that begins with the words "Start Time." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
    If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
    12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
    Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

  • Boot Camp installation knocks out my network connection in OS X?

    I've tried doing an installation of Windows XP in Boot Camp on two different occasions, and both times have resulted in the same odd finding: the network settings in OS X are altered or affected and I can no longer get the computer to connect to any network, either wireless or through ethernet. I can't see anything noticeably different in the settings, but nothing seems to be able to get it to connect. The only thing that has saved me has been doing a restore from Time Machine to right before the Boot Camp install. It makes no sense to me what might be happening here and I haven't found other reports of this. Anyone have any ideas?
    (If it makes any difference, when I got the new MacBook, I did a migration of a 10.4 system from my PowerBook G4 and sometimes wonder if something weird was inherited from that... but that is just a pure guess in the dark. And since, I've had the WIndows 7 beta and RC running in Parallels and Fusion with no problems. But I'd like the Boot Camp option.)

    Free space? 15GB or more free.
    chkdsk comes up clean?
    cleaned out temp/tmp and cache?
    Programs can be repaired right from the control panel "Programs"
    Go into Services to check properties and make sure Apple Mobile, Bonjour, iPod etc are all set to running and automatic. I have to restart all of those usually to get my iPod to connect.
    Windows 7 DVD to check for system repairs.

  • WinXP SP3 and Boot Camp 2.1 | Win BSOD ATI card not correct!

    Configuration:
    Loaded and OEM WinXP SP3 on an iMac with Boot Camp V2.0. All worked correctly.
    Immediately after Boot Camp 2.0 completed installed Boot Camp V2.1. All worked correctly.
    Problem:
    Working in Windows the OS triggered a BSOD (Blue Screen of Death) after the OS was up for approximately 10 minutes. This was a repeatable problem.
    Investigation:
    Downloaded Windows DeBug utility to analyze the crash dump files from the BSODs. For reference on how to read the Windows dmp files and how to use Windows DeBug utility see the following link.
    http://www.networkworld.com/news/2005/041105-windows-crash.html
    Determined that the fault was caused by a driver file ati2mtag.sys.
    Checked the version with the latest availble from the manufacturer ATI. It was the most recent version
    Analysis:
    In Windows right click on My Computer, go to Properties.
    Go to the Hardware tab in Properties, and then to the Device Manager, drop down the Display adapters. The model shown was a Mobility Radeon HD 2600 XT!
    This is WRONG, the video card in this iMAC is a ATI Radeon HD 2600 Pro.
    Conclusion:
    Windows and or Boot Camp loaded the incorrect video drivers for the video card.
    Solution:
    1. Download and install Dot Net 2.0 because the ATI driver installer requires this level to install required drivers. The download is available at the following link.
    http://www.microsoft.com/downloads/details.aspx?FamilyID=0856EACB-4362-4B0D-8EDD -AAB15C5E04F5&displaylang=en
    2. Go to ATI driver support page and download the latest Catalyst driver for 32-bit XP.
    http://game.amd.com/us-en/drivers_catalyst.aspx?p=xp/radeonx-xp
    3. After download, launch the installer, just proceed with the installer until it gets to the point where it pops up an error message saying that the installer could not find a suitable driver for your hardware.
    4. Close out the installer and right click on My Computer, go to Properties.
    5. Go to the Hardware tab in Properties, and then to the Device Manager, drop down the Display adapters, and you should see Mobility Radeon HD 2600 XT, this is incorrect.
    6. Right click on the video card and choose Update Driver, you will be now see a Hardware Update Wizard.
    7. It says Can Windows connect to Windows Update to search for software? Select No, not this time, and click Next... Now you should see What do you want wizard to do? Select Install from a list or specific location (Advanced), and click Next.... On the next page select Don't Search. I will choose the driver to install, click Next....
    8. On the lower right corner of the Wizard, Have Disk... Now click Browse and go to C: > ATI > Support > Driver, and select the inf file in there, click Open.
    9. Scroll through to locate and then select ATI Radeon HD 2600 Pro, and install that, you might get a message saying this driver isn't certified, ignore it and continue.
    10. After completion, reboot.
    My system is now running correctly, no more BSOD's!

    hmm, is it possible that the same problem of the imac is mine on the macpro with 2 ati 2600 cards?
    from where do you know that the recginized xt card is wrong and it must the pro version? cause of the 256mb to 512mb at the offical xt version?
    plz take a look at my problem thread:
