Ethernet issue Windows 8.1 Boot Camp

Installed Windows 8.1 on boot camp - Macbook pro mid 2010. Everything workes very well except for - Ethernet works at first, but then stops working completely and I cannot get it to work again until I reboot. Happens every time, and no alert in Windows error logs. Sometimes, it works for 10 minutes, others 2 minutes. Can anyone think of anything? Also works in OS X ML.
Thanks!

That's exactly my problem! Thanks for identifying it. I was using Wireshark to see what's going on... was only seeing my NIC throwing ARP b-casts on the wire to find the gateway.
There are quite a few advanced settings... did you disable all of them? or only ARP offloads? Flowcontrol? Checksum offloads? How about Ethernet@Wirespeed? I'm wireless at home right now but at the office I have the exact symptoms you're describing...
MANY thanks!

  • Windows 7 and boot camp issue

    On an iMac a1224 I installed windows 7 then boot camp from the os disc. Bootcamp version 2.1 was installed. The current installation and set up guide suggested updating bootcamp to 3.1 however that particular update requires version 3.0. That being said, is it necessary for me to update my version 2.1?
    Thanks

    Leeopard huh?
    You need Snow Leopard w. 10.6.x to get 3.0.
    If it works and no issues fine though probably the first time I have read someone did.
    BC 2.2 was more about XP and some support for Vista.

  • Windows 7 in boot camp - two finger click and drag issues

    Hey everyone. I have Windows 7 on Boot Camp (MacBook Pro mid-2010, Mac OS X Lion) and I cannot seem to click on a window with one finger, then use a second finger to drag it. Every time I try it brings up the right click menu. Is there any way of fixing this? I want to be able to drag, darn it! Thanks.
    Grant

    Having had the same issue on my MacBook Pro with Boot Camp 5.0.5033 on Windows 8, workaround being external mouse, I have found the following:
    If Trackpad->Two Fingers->Secondary Click is enabled in Control Panel/Boot Camp, in order to Click and Drag one cannot click any place on the trackpad. One must click bottom area of the trackpad with one finger, and then use another finger to drag.
    If Trackpad->Two Fingers->Secondary Click is disabled, Click and Drag works the same way as in Mac OS X: one can click any place on MacBook Pro built-in trackpad with one finger, and then use another finger to drag the window or select a fragment of text. The two fingers Secondary Click, consequently, becomes disabled.
    For me Mac OS X-style Click&Drag is more important, so I disabled two fingers Secondary Click, and assigned Bottom-Right-Corner of the trackpad to be Right-Click instead.
    Don’t know if the question is still open… Hope, however, the info might be helpful to those having the same inconvenience with Click and Drag under Boot Camp.

  • Having issues with installing Windows XP on Boot Camp

    I installed the latest firmware for my MBP along with Boot Camp. I then tried to install a copy of Windows XP that I got from my friend (we'll name him Mr.Limewire). Anyways, I've tried to use 2 different copies of Windows XP and Boot Camp does not detect the cd still (it keeps saying to insert the Win xp cd). I believe I have using the full version of Windows XP. If a copy of XP is burnt on a Mac would that affect anything?

    You really need to use a legitimate XP installation CD - a downloaded copy isn't worth the time for many reasons. Even if you did get it running, you can't register it and will have to reinstall a valid copy all over again to use it.
    Also read the BootCamp FAQ's - XP must be a service pack 2 (SP2) release. If you don't see a folder "SP2" on the CD or some reference to it then you likely have a pre-SP2 release.
    Another option is to slipstream SP2 and create an updated XP installation CD -

    but even this would be waste of time without a valid XP install disc.

  • Time Capsule issue with backing up Windows partition via Boot Camp

    I just bought the macbook pro and time capsule. I set up a 25GB Windows partition using Boot Camp and I have set up a Time Capsule to handle the backups. Time Capsule seems to backup the OSX hard drive partition fine, with the historical versions of the drive displayed correctly. However, with the Windows partition the Time Capsule appears to be backing up any files that change, however there is no version control showing up in Time Machine. In other words, I ONLY see the Windows partitioned drive as backed up in the "Today (Now)" screen. Any historical dates the drive shows up shaded and I cannot access it. Is there a way for Time Machine to manage the Windows partition in the same way as it does for MAC OSX drives?
    John

    Why is it so hard?
    1000 and 1 times: the drive must have FREE contiguous unfragmented space and some files are blocking and preventing.
    Some are able to find and delete, some by booting from another hard drive or OS X DVD to repair and/or run iDefrag.
    Or.... backup; erase; and restore.
    ie, CLONE your hard drive in both directions. My choice would be SuperDuper or Carbon Copy Cloner. They tend to work. Defrag tends to be slow and if there is no backup and there is an error.... well, you'll find out.
    Apple error message is badly and poorly worded. Said so for over 3 yrs and it has not changed or improved though.
    Paragon CampTune 9.5 $19 is great for Boot Camp. And resizing. And Windows 7 may need 2 or 3x what the base minimums listed. 32-48GB at least to be safe. And those are conservative numbers.

  • Windows not finding Boot Camp on MacBook Pro

    Hey everyone. I have Windows 7 64-bit and a MacBook Pro (mid 2010) with OS X Lion installed. When I boot up in Windows, it seems that only half of the time Windows realizes that it is on a Mac. Meaning...only half of the time the Boot Camp program is running in the notification tray, and only half of the time will Windows register the volume up/down, brightness up/down, and keyboard backlight up/down buttons on the Mac. It makes it very difficult to say...adjust the brightness or volume in the middle of a game. I can still go out of the game and turn up the volume in the notification area, but it is becoming a huge hassle. Like I said, this is only happening about half of the time. The other half of the time Windows registers that Boot Camp is on it, there is the Boot Camp icon in the bottom right corner of Windows, and all of my control buttons (brightness, volume, etc.) work just fine. Any ideas on how to make this happen every time? Thanks.

  • Windows 8 and Boot Camp 5 with Mid-2011 iMac12,2 DISABLING INTEL HD GRAPHICS

    There seems to be some issue with this newer Boot Camp 5 and Windows 8 becuase of the Intel HD graphics in the processor. I have a maxed out Intel iMac 27" Mid-2011 with Intel Core i7 and AMD Radeon 6970M 2GB.
    When Windows 8 Pro is first installed with Boot Camp 5 USB flash drive everything seems fine. The Intel HD graphics are detected and so is the AMD Radeon. But if the machine is put to sleep the computer resumes and has a BSOD. The reason is igdkmd64.sys.
    I think the only way I know of to solve this is to disable the Intel HD graphics in Device Manager before the machine begins crashing. On "first" boot the Intel HD graphics are listed in device manager. Later depending on restart, sleep, hibernate, the Intel HD graphics are listed under hidden devices in Device Manager.
    IS ANYONE ELSE EXPERIENCING THIS?
    DOES ANYONE ELSE HAVE A SOLUTION BESIDES THIS?

    I don't know if it's just my iMac that lists the Intel HD graphics, but one day it showed up in Windows 7 and still exists today in Windows 8. Could somebody see if theirs shows up in Windows in Device Manager? Maybe with Show Hidden Devices checked.
    BTW I did a clean install and left the boot camp usb flash drive inserted during the install which automatically installs intel hd and bluetooth and then start boot camp drivers installs after Windows setup is completed.

  • Error 0x80070017 when installing Windows 7 via Boot Camp...

    I've been trying hard to research this issue and haven't come across anything that has worked for me.
    At work, we have an iMac (Early-2009) that we wish to install Windows 7 on. Previous user has left, so I reinstalled Snow Leopard (10.6) and used Disk Utility from the disc to reformat complete to GUID single partition Mac OS Extended (Journaled), which is pretty standard for Macs. Mac OS X installed and booted just fine. I updated completely to 10.6.8 and all other updates. Only installed Microsoft Office 2011 and Firefox.
    So Boot Camp begins...
    Found that the early-2009 model doesn't "support" Windows 7 64-bit, so we are fine going with 32-bit. The 32-bit Windows 7 disc has been used to install Windows 7 using Boot Camp on 2 Mac Mini's (one Intel Core Duo, the other one Intel Core 2 Duo) just a few days ago.
    Opened Boot Camp Assistant, partitioned the 1TB drive equally, inserted the Windows 7 disc, and clicked Restart.
    It boots from the Windows 7 disc, I go through the options, choose the BOOTCAMP partition and format it (I assume Windows 7 is choosing NTFS for me). Click next.
    It copies the files instantly, but then "begins" to Expand the files. It remains at 0% for 5-10 minutes (I can hear the Windows 7 DVD spin down and spin up, but mostly spin down). That's when the error hits:
    "Windows cannot copy files required for installation. The files may be corrupt or missing. Make sure all files required for installation are available, and restart the installation. Error code: 0x80070017"
    I click Ok and cancel the install. Restart and boot back into Mac OS X. And here I am.
    Important Notes:
    I've tried multiple times with a 64-bit disc as well. I will likely go check out another 32-bit disc from our software department, but I know this disc works on other Macs.
    This issue occurred a month back as well when we attempted to install Windows 7 via Boot Camp (so before the hard drive and OS were reformatted and reinstalled). I was hoping reformatting and reinstalling the Mac OS X would solve the issue.
    The Superdrive appears to be working just fine.
    I read somewhere that I need to use repair disk to fix it. Does anyone know if I can repair disk a NTFS partition? Or am I suppose to repair disk the parent drive itself? The place I read it wasn't specific AT ALL and the forum was closed and I couldn't find a way to get a hold of the person. It just said "Repair disk did the trick". People, if you find a solution to your own problem, POST the solution!
    Thanks in advance!

    Yea, I saw that kb article. I verified we have the early 2009 iMac. It's an iMac 9,1 (3.06 24-inch, A1225).
    As far as different hardware, I really don't think so, but I'll have to double check with my fellow employees. The specs all match up, but I'll see if anyone remembers having to replace hardware or send it into Apple.
    I did think of trying an external DVD drive too, I'll see if I can scrounge one up. I'll post if it works or not.
    The employee using the machine knows Windows, but is willing to learn the Mac OS X. Diversify your experiences I always say!
    An added note to the Repair Disk "solution". Turns out you can't run Repair Disk on NTFS partitions or the parent hard drive that contains that partition, which makes since. I can only run Repair Disk on the HFS+ partition which did no good. (This is, of course, from booting up using a Mac OS X Install DVD).
    Mac_Win, thanks for the suggestions!

  • Installing Windows 7 with boot camp as whole partition on 2nd internal hard drive

    Hi all,
    I am unsure what is the recent changes with Apple boot camp. But when I used boot camp utilitiy on my Mac Pro (Mid 2010) to install windows 7 64 bits. It would not install and created a whole lot of problems.
    After I initialise the process to install windows 7 using boot camp utilities, I chose the option to create a single partition to installl windows 7 on my secondary internal hard drive (1TB). After I restarted my Mac Pro and started the Windows 7 installation process, I was unable to install Windows 7 on the BOOTCAMP partition created by the boot camp utilitiy. I got an error something about Windows cannot be installed on the selected forum because the driver contained GPT details.
    I tried to format the BOOTCAMP partition, but it ended up with errors. I tried to delete and recreate the BOOTCAMP partition in Windows setup, but failed with errors again. As I could not go any further with the Windows 7 installation, I had to hard reset my Mac Pro and tried to reboot back into Mac OS X Lion and that's when the nightmare begin.
    Not only I could not boot into OS X, I could not use any of the startup key combinations (i.e. Hold option key to select start up disk, option + R to boot the lion recovery drive, not boot from any external firewire drive installed with OS X Lion). Basically none of the key combinations worked except for the holdingi F12 and mouse key to eject CD.
    The only thing I could boot the Mac Pro with is the windows installation CD and Linux Ubuntu Raring Distro. I can install the ubuntu distro without any issue. However, I could not boot my mac pro back into OS X as Linux does not support bootcamp. The only way I could use Mac OS X Lion again is to delete the partition OS X Lion was installed on, and then I was be able to install Windows 7 without any issue.
    After installing windows 7 I would have to download boot camp and then use the boot camp control panel to restart in the Mac Pro installation DVD and I will have to reinstall OS X again. After installing OS X, I went to System Preference and tried to select Windows 7 as startup disc. But I failed to as it says "Windows 7" Was installed via another utility. I would have to erase the partition and reinstall Windows 7 again using bootcamp utility. If I try to install windows 7 again, the horror I described above repeats again.
    From my understanding, the Boot camp utility creates a new EFI bootrom with Master Boot Record (MBR) in FAT32 format. Therefore I could not boot back into Mac OS X without using boot camp in windows 7 as none of the boot combinations key worked.
    I want to ask if anyone is experiencing the same issue as i do, and if there are any solutions to the problem I am experiencing. I never had such issue before. I was able to install Windows 7 on my 2ndary internal hard drive without issue using boot camp. I don't what has changed. I have googled for solution, I only found something related to XOM but nothing else.
    If anyone can provide me with any help in regards to installing Windows 7 as a whole partition on a secondary internal hard drive. It'd be grealy appreciated. Thank you in advance.

    If you have driver issue, just pre-download the boot camp drivers and save them on an external drive or burn them onto a cd, you will be able to load drivers via the advanced installation option during windows setup, that is if your osx partition isn't actively preventing you from installing win7 on the BOOTCAMP Partition created by boot camp assistant, I find this rather ironic, took me 3 days to figure out this issue, I was stuck without being able to boot into anything beside the windows cd, which wasn't even helpful as I could not install windows as I did not want to delete my osx partition. I lost all my data becsuse of it, as I had no idea what was going on. I tried to recover the partition using testdisk, hfsprogs and gparted in ubuntu life cd but they dont support HFS+. As I could not access osx terminal (couldn't even boot into osx installation dvd with that dreaded MBR created by boot csmp). I could not use pdisk in terminal to restore the osx partition map. Though luck for me. Called applecare and they had no idea what the problem was, and as usual they orgsnised for hard drive replacement. But it was clearly a software issue.
    They will have to fix bay2 for me as I can no longer detect any hard disk connected to that bay.

  • Blank screen when installing Windows 7 with Boot Camp - Mac Mini 2011

    I'm new to the Mac scene, having barely any knowledge on the OS.
    I've been trying to install Windows 7 via Boot Camp on my new Mac Mini (Latest offering from Apple).
    I have an External DVD Drive which I have been using, connected via two USB's to the back of the Mac Mini itself. It's fully functioning, with the Mac recognizing the Drive. I've used it for some CD's and DVD's so far.
    I have a full, licensed copy of Windows 7 Home Premium, bought from the Microsoft Store on a DVD. There's both a 64bit and 32bit DVD, of which I have tried both to install Windows 7.
    I've been through the Boot Camp Assistant software, un ticking both the "Create a Windows 7 install disk" and "Download the latest Windows support software from Apple" because I already have the Windows 7 install disk. I've had troubles downloading the Windows support software from Apple, as it just stops about 1/4 of the download for no apparent reason.
    So once I've made the partition, I insert the Windows 7 DVD into the External Disk Drive, and it reboots. At first it looks like the Disk Drive is working, as you can hear the Disk movement and a blue light on the front of the Disk Drive... But then the screen goes blank, and the Disk stops spinning (from what I can tell). Nothing else happens from then on.
    Is there any reason as to why this is happening?
    Thanks, Dominic

       Yes. Booting from a USB-DVD to install Windows
    The MacBook Air has extra drivers. Some people have edited the script preference plist to add their model Not all USB DVD devices may or may not work.
    Burning electronic versions like an ISO or in .exe format you will see threads where that is the issue.

  • A Few Questions Before Installing Windows 7 in Boot Camp...

    1. New Mac Pro compatible with both 32 and 64 bit Windows 7?
    2. What is the minimum safe amount of space needed on the boot camp drive partition to Windows 7 to operate with no issues?
    3. If one no longer needs the boot camp partition nor windows can one reset things back to factory specs with only the Mac OS on the drive and recover the full drive space like new?
    4. Any good video tutorials out their on installing Windows 7 with boot camp?
    5. This is a big concern for me, lots of complaints the the nVidia drivers in windows are not up to date and this has caused a blank screen to come up. Has this video driver issue been resolved?

    you say Mac Pro, well that means you can put Windows on its own drive, and that you will need to use ATI drivers directly.
    not knowing what your needs are maybe a VM is enough.
    too general to say how large and that can be based in part on amount of RAM installed, programs, data. And with 1TB costing $90 does 25GB vs 50GB vs something else? I mean $10 for 100GB is getting cheap.
    If you intend to buy a Mac Pro then obviously you want 64-bit, and if it is single cpu you don't need Windows 7 Pro.

  • I can't boot from the windows cd with boot camp

    I got Vista up and running via boot camp but now I have a problem that could cause some issues. How the **** do you boot from a windows cd with boot camp!?!? When I stick in the windows based CD (could be the vista install CD -after vista's been installed of course- or a Windows home server restore cd) and hold down the option key I chose to boot from the CD in the menu then the screen goes black as it should and then it says press any key to boot from cd or dvd..... It gives me 5 seconds to press a key and then it conintues to boot into Vista. The thing is when it asks me to press any key I press any and all keys on the keyboard and I get no response and it just boots into vista. This can be quite a problem, what if I need to restore vista via the install CD? I can't chose to boot from it cause everytime it asks me to none of my key presses register. So everytime I have a problem I won't be able to restore or even diagnose it, I'll just have to reinstall vista? I don't think I can even bring up the safe mode or anything like this. The keyboard won't work until I reach the password screen of Vista. I've also tried plugging in a USB keyboard to it and it still doesn't work. So basically I need to know how to make the keyboard work before Vista loads.

    Ok, well I just tried booting from the windows cd and it seems that I lied to ya It seems that you can boot from it. Although I only took it to the point I was comfortable with. The boot resulted in it asking me to install windows and I didn't see any partitions listed or anything, so I chickened out (so to speak) not wanting to take the chance of my Leopard installation getting screwed up.
    It's been a quite some time since I used the Vista boot disc and can't really remember how it went when I used it in conjunction with boot camp beta. Sorry can't give you anymore information.

    If you have a Mid 2010 model: Computers that can be upgraded to use OS X Internet Recovery. If later then see below:
    Install Mavericks, Lion/Mountain Lion Using Internet Recovery
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Internet Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
    Partition and Format the hard drive:
    Select Disk Utility from the main menu and click on the Continue button.
    After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    If you have an earlier model:
    Clean Install of Snow Leopard
         1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came
             with your computer.  Insert the disc into the optical drive and restart the computer.
             After the chime press and hold down the  "C" key.  Release the key when you see
             a small spinning gear appear below the dark gray Apple logo.
         2. After the installer loads select your language and click on the Continue
             button. When the menu bar appears select Disk Utility from the Utilities menu.
             After DU loads select the hard drive entry from the left side list (mfgr.'s ID and drive
             size.)  Click on the Partition tab in the DU main window.  Set the number of
             partitions to one (1) from the Partitions drop down menu, click on Options button
             and select GUID, click on OK, then set the format type to MacOS Extended
             (Journaled, if supported), then click on the Apply button.
         3. When the formatting has completed quit DU and return to the installer.  Proceed
             with the OS X installation and follow the directions included with the installer.
         4. When the installation has completed your computer will Restart into the Setup
             Assistant. Be sure you configure your initial admin account with the exact same
             username and password that you used on your old drive. After you finish Setup
             Assistant will complete the installation after which you will be running a fresh
             install of OS X.  You can now begin the update process by opening Software
             Update and installing all recommended updates to bring your installation current.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.

  • Installing windows xp on boot camp and parallels??

    Hi all,
    I am using a Macbook with a 2GHz Intel Core 2 Duo with 4GB of memory on Mac OS X 10.5.8. I currently have Parallels 5 installed running Windows XP. I need to run Windows off of Boot camp according to the support from the program I am trying to run "Chief Architect X3" as I need to utilize the video card "natively" I believe the word was. Parallels is unable to recognize and use the card properly for this program. So my question is two fold does anyone know if there is a patch that allows Parallels do this? Or can I install Boot Camp on my machine as well with Windows XP so that I can utilize the video card for this program. Do I need to uninstall my Parallels virtual machine? Also programs that are installed via Windows, if I install Boot Camp/Windows and delete my virtual machine/Windows do I need to reinstall those programs? Any and all information is GREATLY appreciated!
    Thanks in advance,
    Laura

    Upgrade to Parallels 6, new build just out. And ask on their forum.
    You have to install XP natively first and then enable under a VM to activate properly.
    Everything will need to be installed. there are few ways to get a VM to a "native" hard drive partition. And Windows activation is another issue.
