Reinstall BootCamp on Windows 7

Hello,
Yesterday, a suden electricity power cut took place in my area, while I was on my Windows 7 partition... After some minutes, the electricity was on again, so I logged on my Windows 7 partition, everything was ok, but the network...
I see the wireless tray icon, not connected anywhere, with a red X on it.
I think that there is a problem with the drivers.
Because bootcamp installs all of the drivers correctly, I think that if I could reinstall bootcamp on my Windows 7 partition, would install the drivers and fix the problem, but I don't know how to reinstall bootcamp, neither how to uninstall and install it again...
Can you please help?
Thanks!

Firstly, invest in a UPS to allow you to protect your modem, router, computer and equipment.
Windows 7 has Network control panel and while it can attempt to do diagnostic troubleshooting of your connection and show if it has connection to router and/or internet, usually it doesn't resolve an issue.
You can do to Device Manager. Rollback or uninstall a driver (but do not disable a device!)
You can always use Programs control panel and it may have "Repair" along with uninstall a program, or uninstall.
I would be worried if a reboot doesn't work that it is hardware, but if that was true then Mac side would not get an internet connection also.
I'd pick up a manual, that is me, there are several good books and references with tips and how to use and get more out of Windows OS.
And there is built in help and any "?" you find in dialogue boxes (Mac has Help menu too but rarely seems to get use)

  • Brightness with bootcamp and windows 8.1 on rMBP 13 2013

    Hi,
    I've googled for this issue and i've found many potential solves of my problem:
    - Turning off adaptive brightness
    - disabling Light sensor in Device Manager
    - deleting SensorsAlsDriver.dll
    Nothing works. I'm actually using Win 8.1 Pro N x64 with installed Media Feature Pack and with the newset updates. It is fresh-installed via bootcamp manager.
    After sleeping and waking up my Mac brightness buttons magically start working!
    What do I suspect?
    When i delete SensorsAlsDriver.dll and uninstall Proximity sensor in Device Manager, after reboot Windows re-installs the sensor, and re-apply the .dll file.
    I dont have an idea how to prevent OS from doing it...and I think it is potential solution.
    Could someone help me solving this problem?

    I've been experiencing this same issue. I have the exact same laptop and running windows 8.1 pro through bootcamp. Everything runs great except the brightness doesn't seem to work properly. Also the keyboard's backlight is maxed out everytime i turn it on no matter what the lighting conditions. This isn't too big of a deal as i can turn it down once its on but still a minor inconvenience. My bigger issue is that the laptop's brightness is set to a certain level when i boot up in windows 8.1 and i can't change the level of it. I've tried disabling the adaptive brightness with no fix. I read somewhere that disabling the generic PnP monitor under device manager might fix it but im worried that it will disable my laptop's screen altogether and have to redo my bootcamp partition all over again. I have the latest bootcamp drivers for apple that were updated in early feb (2014) so I know that's not the issue and i have also tried reinstalling the bootcamp drivers but it just seems to do it again after a reboot. Dont' know any other fixes. I really want to get this working, other than that, bootcamp on windows 8.1 is perfect on my 13 retina pro.

  • Yosemite 10.10.1 Bootcamp Installation Windows 8.1 from an ISO

    Hello,
    as in my topic described I am looking to install
    Yosemite 10.10.1
    Bootcamp Installation Windows 8.1 from an ISO
    I am using an MBP early 2011 without DVD Drive - but I have 2 SSD Drives inside (500GB und 128GB)
    I want to use the 128 GB Drive for the Bootcamp installation, as I need it for some specific Sports Software which is just available for Windows, which was already running on my factory delivered 250GB HDD Drive.
    The Problem is that bootcamp does not tell me there is an option for a ISO installation like it should display on macs which will be manufactured without an super drive. And so i can not install the ISO to the bootcamp drive.
    I have an USB Stick with 8GB and an 8.1 ISO disk.
    I do not want to reinstall my dvd super drive.
    Hope you can help me out with a description on how to do - I am quite technical so can do some tasks ;-)
    Merry xmas

    Yes. It also helps if there are any calculations to be done with disk sectors.
    My optical drive works fine, but I moved to France and didn't bring any disks. Would it be easier and safer to just burn my windows iso onto a disc and run it through bootcamp that way? I'm thinking the answer is yes at this point.
    Yes, if you have a built-in Optical drive, Bootcamp expects to boot from the Optical drive, because it sets the CSM-BIOS layer for Windows to boot from the Optical drive settings in the NVRAM.
    I'm about to head out to celebrate a birthday, but I will post back here in about 14 hours.
    Enjoy the party!
    Do you recommend just buying a DVD and doing it that way? I could easily return my info.plist to normal, and as far as I know, my optical drive works fine. Seems simpler if it would work with my copies of osx and windows. What do you recommend?
    The changes in info.plist enable creation of the USB, but do not influence the boot device pointer that BCA will set when switching to the Windows Installer. My recommendation is to get DVD writable media (DVD+R or equivalent) and burn the ISO to a physical DVD and use BCA to install windows using the BCA USB and DVD media.

  • How do you reinstall 64-bit Windows 7 in UEFI mode?

    I have a PC with a single hard disk and, a while ago now, I installed 64-bit Windows 7 on it in UEFI mode. 
    The disk has two primary partitions: a C: partition which contains my Windows 7 system and other installed software such as Office, and a D: partition which contains only personal data. 
    (In other words, I don’t have a multi- or dual-boot system.)  
    I now wish to reinstall 64-bit Windows 7 into the same C: partition, again in UEFI mode.
    There is a procedure for reinstalling Windows 7 documented on the following MS Web page:
    http://windows.microsoft.com/en-us/windows/installing-reinstalling-windows#1TC=windows-7
    in the section entitled “Using the Custom installation option without formatting the hard disk”.
    The following YouTube video demonstrates this procedure:
    http://www.youtube.com/watch?v=fr_s29MWOA0
    and it looks relatively straightforward. 
    Essentially, the re-installation starts by inserting the installation DVD into the optical disk drive and running setup.exe while still logged on to Windows 7 with an administrator user ID. 
    At the screen entitled “Where do you want to install Windows?”, both the System Reserved partition (the example in the video is a legacy BIOS installation) and the C: primary partition are visible. 
    On that screen, you simply select the C: primary partition and click
    Next, and Windows 7 is effectively reinstalled over Windows 7. 
    Any personal data in the C: partition is preserved in a folder called Windows.old.
    The big question is, does this procedure work for a UEFI installation? 
    The documentation does not state that it works only for a legacy BIOS installation. 
    If I were to follow the procedure, when I reach the screen entitled “Where do you want to install Windows?”, I would expect to see the EFI System Partition (ESP), the Microsoft Reserved Partition (MSR), my C: primary partition and my D: primary partition. 
    Can I simply select the C: primary partition and click Next to start the (re-)installation?
    It appears that nowhere in the procedure do you specify what mode of installation (legacy BIOS or UEFI) is required. 
    Does the installation setup simply use the same mode as that of the existing installation?
    Does anyone have any experience of reinstalling Windows 7 in UEFI mode, using this procedure or any other method?

    Hi,
    It depends. Do you have Windows 7 DVD? Does your computer have a Boot from EFI Drive option?
    Windows 7 DVD can boot in either BIOS mode or UEFI mode. Different UEFI firmware implementations support different methods for handling the installation operation. The processes for booting the computer into UEFI mode for the Windows product DVD are
    the same. If you can find a boot from EFI Drive option, please perform the suggestions as i referred to.
    If you cannot find any boot option, perform the steps below:
    Use Device Manager's Firmware option and select Boot from EFI Internal Shell.
    Use the EFI internal shell, as follows:
    Start the EFI internal shell from the EFI boot menu and select the drive with the Windows product DVD. The following example assumes that the drive is Fs0:
    Shell> Fs0:
    Start the EFI boot application. For example, on an x64 system, run the following command:
    fs0:> \EFI\BOOT\BOOTX64.EFI
    After the application starts, you may be immediately prompted to press a key to boot from the drive to continue. Press a key to continue booting from the installation media.

  • How do I install Bootcamp on Windows 7.

    I have just installed Windows 7 on my Mac Mini and now I want to switch back to the Mac OS. When I hold down Alt while booting up to change OS nothing happens.
    The other option is to install Bootcamp to work with windows. It's already on my mac as I used it to install Windows 7. But there is no option to switch OS with Bootcamp as I can't find it on Windows 7. I've seen tutorials on how to install it with a disk but the Mac mini has no optical drive.
    How do I install Bootcamp on Windows??

    At first I was under the impression i had accidentily deleted the MAC OS but thankfully I haven't. I did a system restore on Windows and when it restarted I held Alt and I could select my OS.
    But I still don't have the shortcut to bootcamp showing in windows. How do you make a bootable USB for Bootcamp?

    You must use the Windows formatter to format your Windows partition NTFS. Please be sure you select the Windows partition otherwise you might end up formatting your OS X partition NTFS.

  • 20" imac won't restart after rebooting under bootcamp running Windows XP. I get a black DOS screen with an error message.

    My imac has been running without problems under OS X Snow Leopard and bootcamp running Windows XP for a long time. I had received a Sony MP3 player and wanted to install the software on my computer. At the time I had a CD in my drive slot because I was getting ready to install some brother's software for a printer I wanted to use. I restarted my imac under bootcamp and started installing the Sony software in Windows XP. I was having problems with the install  and decided to restart XP to see if that would help. It's been several days since this originally happened so I'm not of sure of any more specifics at this point other than I've had to use windows machines for a long time and know that basically when in doubt "restart".
    When my imac was restarting I heard everything spinning up, the white light came on, but I heard no chime, a blue screen came up for about 15 to 30 sec. and then it went to a black screen with DOS characters giving the following message:
    Windows could not start because the following file is missing or corrupt: <Windows root>\system32\hal.dll. Please re-install a copy of the above file.
    I do have a copy of Windows XP, but my first problem was that I still had a CD in the slot and it would not eject. I tried every keyboard combination I could find including: eject button, F12 and holding down the mouse button at start-up and nothing worked. I also tried every other start-up keyboard combination I could find at Apple Support jut to see if I could get my imac to start up under OS X . I finally went on youtube to find out how to remove the CD. I ended up opening up my imac and taking off the cover of the CD drive to remove the disk. After putting everything back together I put in my Windows CD and tried restarting again. The exact same thing happened and I ended up at the DOS screen. Then I thought maybe my keyboard wasn't working so I replaced it with a new one. Same result. I also thought to plug both of my apple keyboards into my windows 8 laptop (hate it!) to see if they worked there at all. They both did so I'm sure the keyboards are not the problem.
    At this point, since I do now have a windows 8 laptop (hate it!) there is no remaining reason for me to keep a bootcamp partition on my hard drive. My question is where do I go from here? I have a current time machine back-up on an external hard drive and I have my install CD for OS X Snow Leopard. How do I get my imac back up and running? Thanks.

    Can you OPTION boot? If so, then choose the OS X volume to boot back into OS X. From there you can use Boot Camp Assistant to remove the Windows volume and restore the drive.
    Boot Using OPTION key:
      1. Restart the computer.
      2. Immediately after the chime press and hold down the
          "OPTION" key.
      3. Release the key when the boot manager appears.
      4. Select the desired disk icon from which you want to boot.
      5. Click on the arrow button below the icon.
    Five ways to eject a stuck CD or DVD from the optical drive
    Ejecting the stuck disc can usually be done in one of the following ways:
      1. Restart the computer and after the chime press and hold down the
          left mouse button until the disc ejects.
      2. Press the Eject button on your keyboard.
      3. Click on the Eject button in the menubar.
      4. Press COMMAND-E.
      5. If none of the above work try this: Open the Terminal application in
          your Utilities folder. At the prompt enter or paste the following:
            /usr/bin/drutil eject
    If this fails then try this:
    Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.

  • Keyboard Layout Problem in Bootcamp Using Windows 7

    Both OSX, bootcamp and Windows 7 are the latest versions and all up to date and I have had this problem ever since I first started using Windows 7. Everything has worked smoothly and without problems except for my keyboard. No matter what program I am in when using windows 7 certian keys do not work as intended. All of the letters and numbers work as intended but things like the question mark key type this like É instead.
    Question mark =É
    Greater than symbol= '
    Less than symbol = "
    The bracket keys = ¨Çç
    backslash = à
    forward slash = É
    Quotation mark = È
    My question would be is this something that always happens in bootcamp Windows 7 that just needs to be changed or is it out of the ordinary for the characters to be bound to keys incorrrectly like this.

    You prob do not have the drivers installed. Takes a separate disc sometimes. There is a box to check during the partitioning and installation which has to do with downloading the latest drivers. You gotta do that to make much of anything work. If nothing else, go to an Apple reseller in your area or Apple Store if you are so lucky, and get some help. Is not the easiest thing to get all that set up correctly, but it does work well if you got the drivers installed. I have an aviation site which is not yet Mac compatible, so also do the Bootcamp thing with Windows, in order to do my thing on Jeppesen. Hang in there and get some help if you need.

  • Macbook pro and Bootcamp for Windows 7 32bit

    looking for advice re setting up Bootcamp with Windows 7 on my new Macbook Pro 13".  Anything to be aware of???
    Cheers

    32-bit only uses 3.5 GB RAM max.
    Home 64-bit uses at most 16 GB RAM.
    Pro 64-bit uses at most 192 GB RAM.
    2011 Macbook Pro can handle 16 GB RAM, and iMacs can handle 32 GB RAM.
    If you want to be "future proofed", buy 64-bit Pro.
    Unless you have already purchased 32-bit and do not want to lose the money invested.

  • 802.11n with Bootcamp and Windows xp

    My 13 inch Macbook connects to my airport network at 802.11n 5GHz dual bandwidth using OSX but only 802.11g works when using bootcamp and windows. My 802.11n network shows-up on windows as an available network and I can type in my network password but it won't make the connection. Is 802.11n automatically active with bootcamp? I am able to connect at 802.11n speeds to my network using my work's Window laptop and a Linksys 802.11n usb card so I know it works.
