Can't install Windows 8.1 because the Bootcamp Assistant-partitioned disk is GBT and not MBR.

I can’t install Windows 8.1 because the Bootcamp Assistant-partitioned disk is GBT and not MBR, and attempting to format the bootcamp disk does nothing. I have read up on this issue, and the only solution seems to be to make a backup of my computer and reformat all disks via 8.1 setup terminal. I REALLY do not want to do that, is there any way to fix this? I’m on OS X Yosemite, if that pertains to the thread.

Interesting. It wouldn’t install because I had FileVault enabled. Huh. Disabling it saved the day.

    I know there are many other threads, but I guess I couldn't find clear answer to this problem. Is that the Apple's server problem or just me?
    I'm trying to install Windows7 via Bootcamp, with FAT 32 formated USB with ISO, on Macbook air 2012.
    Thanks!

    The problem is the encryption and how your notebook handles it rather than a Time Capsule problem. I had similar problems until I updated the WLAN drivers on my IBM T41.
    The way I convinced myself it wasn't an Apple problem was to connect my IBM T41, via ethernet, to my AEBSn. I was able to connect to internet so I knew it was a conflict between my wireless card and the AEBSn.
    I am now using the WPA2 encryption for the AEBS without issue and connecting many different types of hardware; three iPod Touches, two MSI Wind Netbooks (Win XP SP3), one IBM T41 (Win XP SP2) wirelessly and both my 20" iMac and Dell 8250 Win XP (SP2) by ethernet
    The MSI Winds are brand new and they would connect to the AEBSn but couldn't get an IP address from the internet (Limited or No Connectivity error message). The AEBSn was using WEP encryption. After doing a little research I found that WEP was a very common cause of this error message so I switched the AEBSn to WPA2 and everything works fine now.
    Don't assume that because you can't connect via OPEN it isn't a encryption issue because my Winds wouldn't connect that way either...it wasn't until I changed to the WPA2 Personal that they connected.
    You may also need to change the program that handles the WLAN connection, sometimes Windows handles it better but for the newest addition to our household, the MSI Winds, I am using the Realtek utility that matches the WLAN card and everything is hunky dory...
    Finally sometimes firewalls will prevent getting the IP address...doesn't happen often but it has happened to me so I would double-check that by turning off the Windows Firewall and just verify that it isn't the firewall (that's never been a problem with my Apple AEBSn but it was a problem with an older Dlink g model).

  • Can´t install windows 8.1 because boot camp can't partition the disk. I´ve follow many tips but they did´t work

    Thanks

    There are several possibilities.
    1. You do not have contiguous free disk space.
    2. BCA has failed, or you may have a Fusion drive which is causing problems.
    3. You have incorrect permissions on the disk.
    4. Can you boot in OS X Safe Mode - OS X: What is Safe Boot, Safe Mode? - Apple Support?

    If you are on Yosemite, and have a CoreStorage volume (the default), it is not visible on the Windows side. The Apple HFS driver cannot read CS volumes.
    You can verify this by running the following command in OSX Terminal.
    diskutil cs list
    If you get any output, such volumes will not be visible.
    As a work around, if you really need it, check the 'Revertible' value. If it is yes, you can revert it to HFS+ by using the following command
    diskutil cs revert
    Here is the syntax for the command. The LVUUID parameter can be seen as a long string for your Logical Volume. Do not use the Logical Volume Group or any disk UUIDs. If you need the exact command, please post the output from the diskutil cs list command?
    diskutil cs revert
    Usage:  diskutil coreStorage revert
            MountPoint|DiskIdentifier|DeviceNode|lvUUID
            [-stdinpassphrase | -passphrase [passphrase] | -recoverykeychain file]
    Convert a CoreStorage logical volume back to its native type.
    The file system must be mounted and resizable (i.e. Journaled HFS+).
    Ownership of the affected disk and a passphrase (if encrypted) is required.

    Your issue is completely different. You are running Snow Leopard. There is no download for Windows Support software for Snow Leopard, hence the error you see. Snow Leopard Windows Support software is on the Snow Leopard installation disk.
    You need the Snow Leopard installation disk or a replacement for it.

    Welcome to the Apple Support Communities
    Because of a Microsoft restriction, Windows can't be installed on an external drive (there are workarounds, but you need Windows). Apart from that, Boot Camp only works with the hard drive where you have installed OS X, so you can't use it to install Windows on an external drive

  • I just installed yosemite on my mcb pro mid 2012 and installed win8.1 with bootcamp. now i have the problem, when i'm using windows i don't see my mac partition in the "computer" window. there is only the "bootcamp (c;) partition? what's the problem?

    i just installed yosemite on my mcb pro mid 2012 with a clean install. so i only had the new os x yosemite running on my mac. everything went perfect. than i installed win8.1 with the bootcamp assistant and also everything went perfect.
    But here's the Problem:
    When i'm using Windows 8.1 and i go to the "Computer" window where i can find my hdd partition "Bootcamp (c;) there is only this Partition. the mac Partition is missing.
    so i am not able to read the files on my mac Partition.
    Before i installed yosemite and win8.1, i was running mavericks and win7 on my macbook pro and i haven't had this Problem. i was able to see and read my mac Partition also on Windows 8.1???
    is there any solution for this Problem???

  • EXTREME lag after installing Windows 8.1 pro via / Bootcamp assistant

    Hey guys, today I've literally been through **** trying to get this game working on my MacBook Pro.
    I've basically gone out & bought Windows 8, created a partition on my hardrive (of my MacBook Pro) & installed it into that partition using Apples 'Bootcamp assistant'. After installing the operating system I also loaded the drivers which were given to me by Apples 'Bootcamp assistant'.
    I now have the game on the Windows 8 (on my MacBook) which is a £2000 machine... I have got to the menu & experienced extreme lag to the point where I've even managed to turn down all my video settings & it is still lagging a lot despite my high-end computer hardware - here is my computer http://store.apple.c...B/A&step=config#
    I have tried running the game on this website http://www.systemrequirementslab.com & everything is great but it says I don't have the required 512MB of video RAM... It says I have 256MB. This is complete ********? I believe I have 2GB of GDDR5 video RAM. It also says that my graphics card is called 'Microsoft Basic Display Adapter'. So I believe this is where the issue lies. My theory is for some reason one of the drivers which I have installed which was given to me by the Bootcamp assistant is messing with me.
    This is literally all the information I can possibly provide, does anybody know how I could fix this?
    Thanks you!

    If the underlying hardware was exposed correctly by the CSM-BIOS when Windows was installed, your Device Manager should look like this.
    If the Windows installer did not see any devices as your screen indicates, Windows will use generic software-based drivers which will be very slow and painful.
    Rudegar ... I think the Windows installer did not see  any hardware, otherwise there should be HW with yellow triangles with exclamation marks.

  • Can't install windows 8.1 because drivers fail

    I have an Inspiron 1750 with a 1080p (1900 x1020) display and I can't install 8.1 because I get a blue screen that does not contain any pertinent information for the fail. I have another Inspiron 1750 with a 900p display and 8.1 installs on it; but I can't
    leave the update because the HDD are interchangeable for back up reason. When I take the HDD out of the 900p and install it in the 1080p I get the blue screen. Other than the displays, the two PCs are identical - every piece of the hardware - wifi, keyboard,
    etc....
    Foxnews had a banner saying that there was another update (maybe a service pack) coming out, is this going to solve the problem with 8.1? I think that 25% of the PCs have a driver problem with 8.1; it is all over the internet.

    The Upgrade Assistant does not work. I am running Windows 8 and when I ran the 8 assistant it said I had 6 software items that were not compatible and no hardware. I ran 8.1 and it only found 3 software items and no hardware. I have tried to install 8.1
    and it fails just as Dell states. I suggest MS either fix or remove their upgrade assistants because they mislead people and cause major problems as happened to me - complete removal of 8.1 and re-install 8.
    MS destroyed the use of IDE hard drives with Windows 7 and now have destroyed many more pieces of hardware with 8.1 - my guess is that this is being done at a joint venture between MS and manufactures so they can sell more computers.

  • Can I install Windows xp with SP2 with Bootcamp?

    I purchase Windows xp with SP2 and want to install in on my Mac with Bootcamp.  I keep getting a message that "The installer disc could not be found." I allocated 100gb for windows but can't do anything, once this stops the install process.

  • Can I install windows 8/8.1 with bootcamp 4?

    Hi,
    I have a iMac from late 2009 with an intel core 2 duo cpu,According to the apple website I can only install upto win7 on bootcamp 4 & bootcamp 5 in incompaticable. Is there any way I can run win8.1 on my imac without using such softwares as parallells?

    If the Apple site said you can't, then why do you think asking here will change the answer?
    What makes you think Boot Camp 5 is incompatible? If you can install Mavericks then Boot Camp 5 was installed in the Utilities folder.

  • Can I install Windows 7 upgrade version with Bootcamp on my MAC Book Pro?

    I currently don't have Windows on my Mac book Pro.  I am trying to avoid the high cost of the full version.   My friend said they knew someone who was able to use the upgradable version to install it on their PC using bootcamp.
    Also is Parallell really worth the extra cost?  I will be primary working on my OS OPsystem and only need windows for a few specific things.

    Have you actually tried to install an upgrade version of Windows 7 without a previous version of Windows installed ?
    FYI: Google "Windows 7 upgrade double install".  This was primarily to do clean installs of Windows Vista using the upgrade product keys, but it still works with Windows 7.  I use this technique for cases where the owner upgraded to Win7, but didn't make the recovery disks of XP when they originally got the computer (and the computer didn't come with recovery disks,) then the HD fails and so we have to install Windows 7 from scratch to a new HD using the upgrade product keys without any previous copy of Windows.

  • HT4818 I was doing the BootCamp Assistant partition and it freezed  before finishing I had to restart the PB now I have an invisible partition  how can I remove it?

    After trying using again BootCamp 4 Assistant it doesnt allow me to create the partition, I tried using Disk Tools Partition to delete it and the 60GB white space is shown in the Partition menu but it doesnt have a name nor can it be selected and delete with any Partition tool...  HELP

    Thanks mendel1 but I tried but everything in the Partitions in Disk Utility is grey (not available)
    The 500GN hard drive disk size is shown correctly as 499.25GB but the bar in white are the 60GB that it was going to be the Boot Camp 4 partition but it never completed its process since the computer froze.  The only resizing possible is to reduce the white bar to the blue size but the HD becomes 439.25 GB in size      In the ERASE also all options are greyed the disk can not be erased    HELP!

    using MacBookPro late 2012, 13" I5,...... the only problem is cant download the support software, you can see on the pic! any sugestions? dont know how to contact apple, in my region there is no any official apple store so cant count on them. tried to download from mirror souses but there is no one who share those files old version doesnt provide full compatability with apple drivers and there are some issues with older ones that i downloaded from other sourses, so please tell me how to solve the problem and how can i download the new drivers?tryed a lot but still the same problem for a long long time

    i have a question about the update server!! apples server is a specific sours right!? form where you download the updates if there are any. and all apples when check for updates are using the server as a sours to download those updates. lets pretend its a road splited into 2 ways, the left sight gose to apples ubdate server, the right sight gose to sowehere else i dont know where, so is it somehow possible that in network settings the server option changed to another location,meaning when i'm checking for update or want to download, the internet is not connecting the apples server  like changed its way to onother sours which is not providing apples support, and now i can't connect to the apple update server. i know sounds rediculuse but any way as i'm not good in those things so asking to those who might know.
