Installed windows 7 64 bit on my macbook .. but now got my macbook without audio. please help me!

You most likely installed Windows 7 in EFI mode. Can you confirm this?
If you used Bootcamp Assistant to partition your drive, you did not install in EFI mode.
If you selected "EFI Boot" at the boot menu before installing Windows, you started the EFI Boot installer.
Please let us know whether or not you installed in EFI mode because audio not working is a common problem in EFI mode, but should not appear in normal BIOS mode. (Normal BIOS mode is when you used Bootcamp assistant)

  • Warning: Don't install Windows 7 64-bit on Older MacBook Pros

    I totally hosed my machine by installing Windows 7 64 bit on a MacBook Pro that Apple has not deemed to be okay with running Snow Leopard in 64-bit. I have a Core 2 Due, which is fully 64-bit. Windows 7 64-bit runs perfectly on a MacBook Pro, but Apple's Snow Leopard can only handle 32-bits. Crazy.
    I'm guessing Windows 7 updated the MacBook Pro's EFI to 64 bit, which since my Firmware hasn't been updated, can't recognize or load. Some I'm stuck.
    Does anyone know how to return a 64 bit efi back to its original 32 bit version? I've been forced to reinstall Snow Leopard, hopefully the Disk Image I created will be able to bring back my data, otherwise I'm screwed and really ******.

    I don't think Windows 7 would normally modify your Guid Partition Table, but Boot Camp
    (particularly the later versions) is rapidly gaining a nasty reputation for hosing partition maps.
    Test Disk might could help:
    http://www.cgsecurity.org/wiki/TestDisk
    You will need to boot it in firewire mode (if supported) or from an external clone.
    I hope your disk image is good. Rule of thumb for OS Disk Images:
    Make them sparseimage or sparsebundle, do not compress, and last but not least;
    Make 2 of them. Just some friendly advice.
    I have yet to see anyone repair a defective, compressed, UDIF disk image. I have
    successfully repaired sparse UDSP/UDSB images using either disk utility and/or Disk Warrior
    and/or iPartition or some combination of the three.
    I'm not against disk images, to the contrary, I use them almost exclusively for backup lately.
    I mount them, then place a clone or data on them using Carbon Copy Cloner or Chronosync.
    Of course I only use UDSP/UDSB uncompressed images.

    Not using Boot Camp, but you should be able to using virtualization software such as Parallels to run Windows concurrently with OS X.

    Boot Camp doesn't install the drivers. You have the drivers on a separate USB device if you followed directions. Once in Windows connect the USB drive with the driver software. It should startup automatically and install the drivers.
    You don't even need to do that. As downloading the drivers from within Boot Camp Assistant can be unreliable, it is better to get the package directly from here:

    Copy the .zip file to a USB flash drive or burn it to a DVD in OS X. Install Windows as normal, insert the flash drive/DVD in Windows, copy the .zip file to the hard drive, extract it, then run the setup executable.

    It sounds like you are running the student edition which comes with a
    textbook and doesn't support external code such as DLLs, CINs, or
    ActiveX. You might want to check with others at your university and see
    about getting access to an academic edition or a

  • Can I install Windows 7 64-bit on my mid-2007 dual quad core "Clovertown"?

    Hi all,
    I want dearly to install Windows 7 64-bit on my MacPro, but the only online compatibility information says bootcamp 3.1 for 64-bit works with "early 2008" Macs and not "mid-2006" Macs. I'm stuck in between, for I purchased a mid-2007 MacPro with dual quad core Clovertown processors, which are 64-bit. I'm unsure though if I will run into problems trying to use Bootcamp 3.1 in this case (I have Snow Leopard as well). I've called Apple support several times and they basically say they are not sure, but don't see why it wouldn't work. Any thoughts from the group?
    Cheers,
    Ben

  • Can I install Windows 7 (64 bit) on late 2013 edition of MacBook Pro?

    Can I install Windows 7 (64 bit) on late 2013 edition of MacBook Pro using Bootcamp? Before today, I would have never even asked this question due to the large number of users who continue to use Windows 7 in the PC world!  However, there seems to be two conflicting links on the Apple site.
    http://support.apple.com/kb/ht3986
    http://support.apple.com/kb/HT5634
    From the first link, there is a statement as follows: Mac Pro (Late 2013) only supports Windows 8 (64-bit).
    From the second link, the table (under MacBook Pro) clearly states that the Retina, 13 inch, late 2013 edition supports BOTH Windows 8 64 bit and Windows 7 64 bit.
    So the above information is conflicting; and as a result, I am confused!  Thanks for any responses.

    As far as I am aware your computer supports Win 7 and Win 8 - 64-bit.
    Windows on Intel Macs
    There are presently several alternatives for running Windows on Intel Macs.
         1. Install the Apple Boot Camp software.  Purchase Windows 7
             or Windows 8.  For Boot Camp 4.0 and above you can only use
             Windows 7 or later. Follow instructions in the Boot Camp documentation on
             installation of Boot Camp, creating Driver CD, and
             installing Windows.  Boot Camp enables you to boot the
             computer into OS X or Windows.
         2. Parallels Desktop for Mac and Windows XP, Vista Business,
             Vista Ultimate, or Windows 7.  Parallels is software
             virtualization that enables running Windows concurrently
             with OS X.
         3. VM Fusion and Windows XP, Vista Business, Vista Ultimate,
             or Windows 7.  VM Fusion is software virtualization that
             enables running Windows concurrently with OS X.
         4. CrossOver which enables running many Windows
             applications without having to install Windows.  The
             Windows applications can run concurrently with OS X.
         5. VirtualBox is an Open Source freeware virtual machine such
             as VM Fusion and Parallels that was developed by Solaris.
             It is not as fully developed for the Mac as Parallels and VM
             Fusion.
    Note that VirtualBox, Parallels, and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc.  There are performance differences between dual-boot systems and virtualization.  The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech Labs- Virtualization Benchmarks, January 2013 | MacTech for comparisons of Boot Camp, Parallels, and VM Fusion. Benchmarks of all of the above except Crossover can be found in Benchmarking Parallels, Fusion, and VirtualBox Against Boot Camp - The Mac Observer. Boot Camp is only available with Leopard or later. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
    You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive.

  • HT4410 I have just installed Windows 7 64-bit full version Home Premium using Bootcamp and cannot get access to the internet. I installed on a Macbook Air Mid 2012 with Mountain Lion. Are there some drivers that are missing from the Windows 7

    Dear Apple. I have just installed Windows 7 64-bit full version Home Premium using Bootcamp and cannot get access to the internet. I installed on a Macbook Air Mid 2012 with Mountain Lion. Are there some drivers that are missing from the Windows 7 bootcamp install download from Apple

    It is a Total Misconception that the Support files are installed when you are installing Windows, even if the USB drive that holds them is inserted in the system when doing the Windows install.
    You must always Run the Setup.exe files from the support files or run the drivers individually once Windows has finished installing and booted to the desktop.
    Also you really need to run the Boot Camp Control Panel Applet and check for updates as not all the newest drivers for full function of all the hardware is included with the original support download. That download is basically a generic version to get the system working and without doing the updates not everything will work properly.

  • Cannot install Windows 7 32-bit using Boot Camp

    I have one of the new iMacs (late 2012) and I can't install Windows 7 32-bit using Boot Camp. Whenever I try to being the installation using the Boot Camp Assistant, I always get the following message: "Need 64-bit Windows installation USB drive or DVD. Boot Camp only supports 64-bit Windows installation on this platform. Please use an USB drive or DVD which contains 64-bit Windows". I have successfully installed 32-bit Windows on my Macbook Pro that is running the same version of Mac OS X and Boot Camp, but I don't know why on this new iMac it doesn't allow me to. Apple's documentation states that I should be able to install either 32-bit and 64-bit without any problem, but this is not the case here. I can't find anything about this problem/error on the Internet either. HELP!!!

    Yes, circumstances do change but if Apple is, as they claim to be, serious about seamlessly migrating what is still a large and dominant market share of users from Windows, supporting 32 bit versions is not a nice to have, but a must have.
    I don't see why users have to make excuses when there is a clear shortfall of what is promised.
    In other discussions, there is talk of an opportunity for Apple to make a significant impact, as Windows 8 has deviated so much from the comfort zone of traditional Windows users. But to make that change, Macs have to support what is still a primarily 32 bit environment in the installed base.
    As for the use of VMs, I had a tough time migrating out of Parallels 6 after an upgrade to Mountain Lion broke compatibility so IMHO it is not a long term solution unless you are happy to hand out $50 every 2-3 years just to support the same functionality.
    Use Virtual Box, it's free.
    32 bit may have a reasonable user base but it's going away fast, if you must use 32 bit Windows and won't use a VM your choice is limited.
    Buy a PC, or buy an older Mac.
    The rest of your post is speculative and I won't go there.

  • How do you overcome a blackscreen upon beginning installation of windows 7 64-Bit on a MacBook Pro5,1?

    Hello All,
    I have a MacBookPro5,1, upgraded to 8gb RAM running Mac OS X Version 10.6.8.
    Apple states that this model is capable of installing Windows 7 64-Bit.
    But when I try to install Windows 7 via Boot Camp Assistant, everything goes to plan until Boot Camp restarts the machine where a Blackscreen appears and does not show the windows installation screen. The machine is doing something in the background but then appears to power off. I have to press the power button twice, one long press to stop whatever it was doing then one more to power back on. I can get back into the Mac side with no problem.
    I am certain bootcamp does not have the relevent video drivers for the windows installation to use...
    I am using a Microsoft certified Windows 7 Professional SP1 image file burnt to a DVD-R, the image was downloaded from Microsoft as part of their student deals.
    How do I get the blackscreen to go away?
    Kind Regards,
    tmanz

    Okay,
    So I still have the problem.
    I was able to upgrade my Mac OS X to Lion using a Retail DVD and this gave me Boot Camp v4.0.
    Followed the steps, burn't the downloaded drivers to a DVD. Then selected install on the Boot Camp and the MacBook Pro still goes into a blackscreen where I should see the Windows 7 installation screen.
    This problem seems to be similar to the apple problem with their iMac's TS3173, but I am dumbfounded as to why I have this problem. I don't think anyone else out there with a MacBookPro5,1 has this problem.
    I think If I had a solution as in TS3173 for the MacBookPro5,1 it would solve my case. Really I need the nVidia drivers for the GeForce 9400M, I tried getting these from the Boot Camp drivers but these are in exe form which would not be detected by the Windows 7 installer.
    Is there anyone out there that understands my problem and can advise me?
    Your time and efforts are greatly appreciated.
    Kind Regards,
    tmanz
