Fusion Drive on Windows

Hi everyone,
I'm planning to buy iMac Late 2012. I'm going to order with maybe 1TB Fusion Drive and wanted to ask if it will work with windows... So what do you guys think?
thanks, Enes

A computer with Fusion Drive works properly with Windows on Boot Camp. Only iMacs with 3 TB Fusion Drive have problems to install WIndows on Boot Camp.
Before using Boot Camp to install Windows on the Mac, see if you need a virtual machine or Boot Camp > https://discussions.apple.com/docs/DOC-3321 Also, note that you will have to install Windows through a USB drive, or buy the USB SuperDrive if you have Windows on a DVD

  • Cannot access mac fusion drive in bootcamp windows 7

    My Fusion drive  imac cannot access the Mac fusion drive in bootcamp windows 7. even  I installed the bootcamp 4.1on windows 7.  It is trouble as I cannot get my file in the mac drive in windows.
    I don't have this problem in my old imac 2008.

  • Bootcamp & 3tb non fusion drive - Windows 8.0 and 8.1

    Is it true that on an IMAC 2013 with 3 tb non fusion drive it is possible to install, via bootcamp, windows 8.0 and not 8.1. I have read on internet a lot of discussions about the the 3tb problem and the fusion problem, but only speaking about the windows 8.1.
    Besides if you read on the release notes of bootcamp 5.1 seem Aplle solved both problems related to 3tb and fusion drive; is this solution related only to windows 8.0 ?
    Please, can someone give me a clear statement about this before buy the IMAC and windows?

    my imac 21" mid 2011 run windows 8.1 update 1 just fine
    got it with Lion
    installed windows7 64bit ultimate from dvd in bootcamp
    updated to mtn lion

  • Installing Windows 7 on Late 2013 iMac w/ Fusion Drive

    Sorry in advance for the long post, but I have tried to exhaust all possibilities, and bring as much knowledge about our environment to the table to avoid confusion.
    Here's our goal:  Install Mac & Windows on a Late 2013 iMac with a 1TB Fusion Drive
    Install our Mac Image with Deepfreeze on Partition 1
    Install our Windows 7 x64 Image with DeepFreeze on Partition 2
    Here's why our goal cannot work out of the box:
    Deepfreeze for Mac, is not supported on a Fusion Drive. Now before anyone says "just don't use deepfreeze"...we are using it, and that is that.
    In order to get our existing image to work on the iMac, we had to split the Fusion Drive.
    Splitting Up the Fusion Drive
    We booted into Recovery, Opened up terminal, retrieved the LvGUID, deleted it, and split up the SSD from the HD.
    So now, we have a 128GB SSD, and 1TB HD showing up under Diskutilitiy.
    We then partitioned the 1TB HD, into two, 500GB Partitions. One for Mac OSX 10.9.4, and the other for Windows.
    The 128GB SSD is going to be used for scratch space, temp, etc. And is irrelevant at this time.
    Deploying our Mac Image
    After splitting the Fusion Drive, we netbooted and installed a "NetRestore" of our image. Worked completely fine, no issues. DeepFreeze Works fine, the 128GB SSD shows up just fine, and the other 500GB Windows Partition shows up fine. All drives / partitions can be written to with no problem.
    Deploying our Windows Image
    Deployed our Windows Partition image as we have done in the past, by booting into a windows PE Disk. (We have other various 2009, 2010, and 2011 iMacs across campus, with NO FUSION DRIVES installed, and dual boot them successfully using the same procedure. Minus the splitting of the fusion drive part of course) After the Windows image is deployed to the windows partition, we then boot it up to a Windows 7 Install disk to fix the MBR, Bootrec, and BCD options to allow it to boot properly. Here's where we run into issues: Upon getting the Windows 7 Install screen, the USB Keyboard and Mouse, DO NOT WORK.
    Here's the options we've tried to get them to work properly
    1. Tried another known working Mac USB Keyboard & Mouse = Failed
    2. Tried a known working Windows Keyboard & Mouse = Failed
    3. Plugged Just a known working Mac Keyboard into each USB Port to see if recognized = Failed
    4. Plugged Just a known working Windows Keyboard into each USB Port to see if recognized = Failed
    5. Plugged Just a known working Mac Mouse into each USB Port to see if recognized = Failed
    6. Plugged Just a known working Windows Mouse into each USB Port to see if recognized = Failed
    7. A Windows 8.1 Recovery USB will boot and the USB Mouse & Keyboard are recognized and installed! (YAY!!) However, we cannot repair a Windows 7 install with Windows 8.1..
    BootCamp Drivers & Support Media
    Downloaded the Current BootCamp Support drivers to enable the USB and other various drivers to be loaded during setup (Placed the $WinPEDriver$ and AutoUnattend.xml, and BootCamp folder on the Root of a USB, and modified a Windows7 Installation disk and placed on the root as well) The drivers do not load. Have also placed on a brand new USB2, and USB3 flash drive formatted at FAT32, to see if that made a difference, which it did not. The BootCamp USB made within Mac, it loads saying "Now booting into Boot Camp Assistant Created USB Drive..." or something like that (Don't remember the exact Message)
    Side Note:
    Restored Fusion Drive to its original State, and booted from the BootCamp USB drive, still no usb Mouse & Keyboard Support.

    I have same issue
    Tried everything differend hdd,ssd  as well
    Basically when trying instal win 7 via iOS maverick when reboting and windows booting to the first scree everything freezing cant do  much.
    Also tried install clear ssd without any system, but soon after format ssd or hdd I have error that I cant use this disk to install windows!!!!!!!!!!!!!!!!!
    What is funny Windows 8 installing without any problem!!!
    what is going on APPLE??wher is support
    This issue I have only on Late 2013 on my other Late 2012 this issue not exist and everything working as should.

  • Best way to install Windows 8 on an iMac with 1tb Fusion drive

    I just ordered my first iMac. Not my first mac, I have owned numerous Mac laptops in the past but am finally ready to make the switch for my main desktop .
    Now I need to installed windows 8.1 because I need to run visual studio. That is literally the only app I need to run.
    Ordered with the below specs:
    27" imac
    i7 processor
    1tb fusion drive
    16gb ram.
    I am thinking of two options:
    1) use parallels or vmware fusion and create a 200gb windows virtual machine and give this machine 6gb ram (4gb is recommend by more couldn't hurt). since the fusion drive works at a block level, my windows OS and vs should parts of the VM file should get moved to the SSD as I will be using it a lot. my main goal is max performance. i will be working on metro apps (not windows phone apps). any recommendation on which is better? parallels or vmware? stability and performance is key. i don't need any fancy UI integration and i won't run any games. happy to run windows in fullscreen mode.
    2) create a 200gb partition and run bootcamp. cleary more stable but will it be faster than above because i am assuming the ssd caching will not working here?
    per mircorosft website they give instructions for both options above, but i am looking for realworld experience in what will get be most stability in terms of network IO (working on UPNP apps so need stable network bridging) and then performance is key.
    HDD size is not a big deal for me as most of my media lives in my synology NAS.

    virtual machine will be more stable
    bootcamp will be faster but the only place you will notice is if you play new 3d games on diwndows

  • Windows will not boot to my boot camp partition on a DIY fusion drive - gives "No bootable device found" error

    I have a MacBookPro 9,1 (mid-2012, non-retina) running OS X 10.8.2.  Here is what I have done to my system:
    Installed Windows 7 x64 Pro to a boot camp partition; installed all windows updates.
    Using WinClone, save an image of this boot camp partition.
    Removed optical drive and HDD.
    Installed HDD in place of optical drive.
    Installed SSD in place of HDD.
    Booted to recovery partition, installed OS X on a flash drive.
    Booted to flash drive, created fusion drive using [MacWorld's instructions](http://www.macworld.com/article/2014011/how-to-make-your-own-fusion-drive.html)
    Booted to recovery partition on flash drive.
    Restored system to fusion drive from a Time Machine backup. Unfortunately, it seems that because I never installed OS X on my fusion drive, I do not have a recovery partition. But that's an issue for another day.
    Using Boot Camp assistant, created a boot camp partition on my HDD.
    Using WinClone, restore my Windows installation from the previously created image.
    Now, Windows boots to a black screen telling me that it can't find a bootable device. I have tried a few things to resolve this, all without effect:
    I know that VMware Fusion has to prepare a boot camp partition in order to virtualize it, so I figured it might inadvertently fix things. Alas, while it *did* successfully boot my boot camp partition into a virtual machine, I still can't boot into Windows.
    I figured I'd just try to reinstall Windows. Surprisingly, my system booted to my Windows install disc, which was in my original optical drive (which I had put in a USB case). But, Windows refused to install, giving me a an error 0x8030024. It seems the solution to this issue is to disconnect all drives but the one on which you want to install Windows, which is something I would dearly like to avoid. It would be a pain, but more than that, I'm afraid it would bork my fusion drive, even if I'm careful to never boot to OS X with the SSD disconnected.
    A lot of places said that this error results from a borked MBR, and suggest using a tool like gptfdisk to rewrite it. I followed the instructions [here](https://discussions.apple.com/thread/4144252?start=0&tstart=0), but *that* didn't work either.
    I am now completely at a loss as to how to proceed, and Google isn't much help either.
    In conclusion, here is some information that you may find helpful:

    My setup is very similar to your's, Ryan, on a Mac Mini5,2 and the ordering is different and Winclone was not used.
    1. New Mini with internal 500GB with Mountain Lion(ML), put into an external FW enclosure, so the Mini can/could be booted using an external drive for contigency.
    2. Replaced internal stock HDD (500Gb/5400rpm) with SSD/HDD (256Gb SSD/1TB 5400rpm).
    3. Installed W7 x64 on 64GB partition on HDD, which was a single-partition drive to begin with.
    4. The remaining HDD partition and the entire SSD was put into a Fusion drive.
    5. Using Command-R, new ML installed on Fusion HD.
    Here is what I currently have...(Disk0 - SSD, Disk1- 1TB HDD, Disk2 - Fusion, Disk3 - External FW).

  • Can I bootcamp Windows on SSD instead of Fusion Drive?

    Hi guys,
    I have a base retina iMac which I have boot camp Windows 8.1 on it. However, I would like to know if I can improve the performance of Windows 8.1, like installing Windows 8.1 on SSD part instead of HDD?
    If not, how can I improve the performance of windows 8 on fusion drive?
    thanks

  • Unable to install Windows on an 2010 iMac with home-made Fusion Drive

    Hi there,
    I've been very happy using mi iMac eversince I installed the SSD alongside the HDD.  Only recently I tried to install Windows 7 but it doesn't seem to work.  The installer runs, it seems as though Windows is installing but it doesn't ever seem to be able to boot.  I've tried countless times.  Everytime it boots to Windows it shows nothing but just a black screen with the cursor blinking at the top left corner.
    Now, when I home-made the Fusion Drive the Mac OS was only 10.8.2 or older and I know that with 10.8.3 Apple has made improvements towards boot camp and especially the 3TB HDDs.  I wonder if this could have anything to do.
    Anyway, please enlighten me as to what is it that I need to do to make it work.  I've been reading something about the position in which the Windows partition resides compared to GUID and EFI but honestly I have just the tiniest idea about all that.  Just for the record, the following is what shows in the Terminal after diskutil list command:
    diskutil list
    /dev/disk0
       #:                       TYPE NAME                    SIZE       IDENTIFIER

    Hope you can help..!

    Hello again, by reading a couple of posts I learnt the steps and so, using an external OS I repartitioned the two internal drives making sure the Windows partition wasn't part of the Fusion Drive.  I was very excited as I was sure it would work and went ahead and started the Win7 installation even before the MacOS was restored into the iMac.
    No good news though.  The installer run as expected however, when the time came for the iMac to boot from the newly installed Windows7, all I saw was a blank screen and a blinking dash at the top left corner of the screen.
    Lastly, this morning I woke up to see that my old system was fully restored from Time Machine external back up.  I also leart that using the Boot Camp Assistant I could remove the Windows partition that I created on Terminal from the external OS, which was surprising, I honestly thought that that partitioning arrangement would be off-limits for the Boot Camp Assistant.
    Still, I haven't been succesfull installing Windows back to my Mac, can anybody help?

  • Mavericks, 3TB Fusion Drive, Windows 8 (again!)

    I am so confued now, my head is spinning.
    I have read probably 18 different posts now on how to install Windows 8 on a 3TB fusion drive, and none of them are complete, or give a step by step.  I'm on a new late 2013 model iMac running Mavericks 10.9.1.
    Is there a way to just wipe the whole thing, (after creatin a Mavericks boot disc, I would assume), blow away the current configuration and just re-set it up so that windows gets 4th partition on "core data" volume?
    Here's my rundown:
    - Boot camp assistant runs, creates windows partition, but then partition is inaccessible for install by windows. (GPT)
    - Disk ultility fails to create a new partition if the first mac partition (the main one) after downsizing the main OS X partition
    - No further partitions can be created beyond a second Mac partition in disc ultilty.
    Fortunately my OS X Mavericks is still working, but my partitions are now what looks like a mess.
    In the debug mode of disc utility:
    Macintosh HD (Mounted)
    EFI (unmounted)
    Macintosh HD (Mounted)
    BOOT OS X (Mounted)
    EFI (unmounted)
    Macintosh HD (unMounted)
    Recovery HD (unmounted)
    I'm about ready to take it to the apple store and jusrt ask if they can thrown in a regular drive, or if they can fix it.  My fear is that if I can't fix it, neither can they.
    Anyone find a way to do this?
    I found one article that showed an unsupported methog using a time machine backup, but Mavericks has already failed to use my Mountain Lion backup (I had to recover the data manually) so I can't really use it to re-setup this mac.
    if anyone has a "clean" install method, please do share!  I'll buy you beer.  Seriously.
    Thanks!

    OK, I managed to get the computer back to "stock".
    I had to used system rescue CD (it's a Linux tool with Gparted) to blow away all the messed up partitions on the 2.7GB hard drive (part of the fusion drive).
    Next, I created a bootable USB by downloading the Mavericks installer app from the app store, and then reloaded OS X.  I had to use disc utility to do this, and disc utility picked up the missing and incorrect partitions, and recreated all of it. (There are a lot of steps involved here...)
    Anyway, I got back to square 1.
    Again, I tried to use bootcamp assistant to install Windows 8, and now it is failing on the partition selection screen. Windows can't install because the bootcamp partition is labled as disc1, and windows can only install on disc zero.
    Next?

  • Can I partition a 3tb fusion drive on a 2014 imac27", with boot camp, to let me install windows 7?

    I have used boot camp to create a partition for Windows 7 on 3 earlier Macs (iMac 24" 2007 / Mac Pro 2009 / Macbook Pro 2009) as well as a recent Macbook Air 2012.
    My main reason for this is to use Sage Account/Payroll, and also a couple of other Windows-specific programs.
    I have just replaced the old iMac with a new iMac27", with a 3tb fusion drive, and want to partition it to install a new oem copy of Win 7 sp1.
    However, I found an article on this (link: http://twocanoes.com/winclone/support/installing-windows-on-a-boot-camp-partitio n-on-a-3-tb-fusion-drive) implying this might not currently be officially supported by Apple & boot camp assistant, and providing a workaround procedure to create 3 partitions. The article begins with this note: "Important Note: This help document is for reference only, superceded by updates to OS X that include support for 3TB drives and Fusion drive in Boot Camp Assistant.  Use Boot Camp Assistant to create the Boot Camp partition."
    I have two questions:
    1 - Can anyone advise if updates have now been made, to provide this support for partitioning the 3tb fusion drive?....and if not, is this likely to change soon?
    2 - If this is still not officially supported, can anyone advise if they have successfully created a Windows partition on the 3tb fusion drive & installed Win 7?
    Thanks in advance. 

    Based on Apple's knowledge base. this configuration is supported for Windows 7 x64 and 8 using Mountain Lion 108.3 or higher. Simply use BootCamp Assistant to set it up.
    See here:
      http://support.apple.com/kb/HT5639?viewlocale=en_US&locale=en_US
    and here:
      http://support.apple.com/kb/TS4441
    For your application, you might also consider virtualization software like VMWare Fusion or Parallels.
    I use both BootCamp and VMWare Fusion. Fusion is much easier to install, more flxible, runs at the same time as your Mac applications etc. For typical applications, there is no notable performance degradation.
    If you need high performance graphics for gaming, BootCamp is still the best way to go. For all other applications, I prefer VMWare.

  • IMac, Bootcamp, Windows 8.1, Fusion Drive - not working

    Hey there,
    as many other here I habe problems installing Windows 8.1 on my iMac (late 2013) with a 3TB Fusion Drive.
    I'm playing around with that installation about 3 days or so.
    Even got a problem where I couldn't delete  partition and suddenly got a second logical volume group
    Somehow I could fix that.
    I tried to install it with the help of Threads which are already opened here but had no success.
    I just want a plain Windows version, not on that SSD part of my Fusion Drive, just about 500GB of Windows
    And maybe there is a chance without reinstalling Yosemite?
    Hopefully you can help me through that process.
    And many thanks in advance, here is the output of my disk:

  • Can I install Windows on my iMac 27, 3TB Fusion Drive, late-2012 with Boot Camp 5?

    Hello. When I first opened the Boot Camp Assistant app, it said it could not work with the 3TB fusion drive. With the updated version of Boot Camp, the option to install Windows appeared. I tried to install Windows 8, but the loading bar stopped moving. I waited for hours, but it still did not move. I decided to quit the app, and re-open it, in order to try again. It crashed, and would not open. So I restarted my system and when I did that I noticed that I had about 1GB or so left of storage. This shocked me, because the disk was just suddenly filled for some reason. In hopes of fixing this I used an app called 'CleanMyMac' to try and recover the disk space. And as I thought the disk space returned to normal. However when I went to Disk Utility and clicked 'repair disk' it said this...
    There is only 1 partition, so the Boot Camp process did fail.
    I don't know whats wrong with my system though? I would like to install Windows, but I'm worried that I might recieve errors again. I have not got Apple Care, but I'm playing on buying it soon, due to it being almost a year since I bought the system.
    Maybe I did something wrong when trying to install Windows with Boot Camp? I don't know, but if possible can someone please tell me if I can install Windows and if something is wrong with my system.
    Here is some additional screen shots of the type of system I have.
    Thank you for your help with this issue!

    Which copy or version of Windows? and how where was it purchased?
    my window installed itself perfectly on another computer.
    One copy and you want to activate on two computers?
    With 16GB, it will try to create 16GB hibernation file, 24GB page file, and need 20-30GB for the OS, plus room for temp, cache, applications, 9GB just temp to install SP1 update(s). 
    did you create 80GB or larger partition?
    also, some macs with ssd + hard drive have issues, and of course you need Windows 7 64-bit home premium (Pro to use more).
    OWC has up to 32GB, not cheap.

  • How do i install Windows on SSD with a Fusion Drive?

    Hello everyone,
    i currently have a perfectly working iMac late 2013 with 1TB Fusion Drive.
    I would like to install Windows INSIDE A SSD PARTITION.
    Classic bootcamp will store Windows inside the mechanical hd and this slows things...
    How do i put windows inside the SSD? Does anyone have a step by step tutorial?
    Thanks.

    What is the purpose of this?
    I have my drive formatted case sensitive on purpose for more security and stability.
    Why on earth would y'all choose to do this?

  • To install Windows 8 OS on a new iMac using Boot Camp, what size "partition" should I allocate for Windows on a system with 3TB Fusion drive?

    I am trying to install Windows on a new iMac w/3TB Fusion drive. The system crashed on my first attempt but appears to have partitioned the drive correctly before crashing???  So, what size partition does Windows 8 need to operate effectively?  Is "more" better??? or just over-kill?  And, has anyone installed Winodow 8 on an iMac...and how did it work?  Would apps like "Parallel Desktop" or "VM Ware Fusion" be a good idea and troubleless?
    I will try again but not too confident that it may get worse before it gets better.
    Regards....?
    P.S.  I configured this iMac with the i7 processor 3.5GHz with Turbo Boost to 3,9GHz.  When I select "About this Mac" it diplays my i7 processor as a 3.4GHz instead.  Do you think they ran out of the i7 3.5GHz and shoved a i5 3.4Ghz in the iMac to meet deliver schedule???  I there a way to check the real-time speed of my processor??.

    It depends on your uses. See > https://discussions.apple.com/docs/DOC-3321 Windows 8 works properly in Boot Camp, always that your iMac is compatible > http://support.apple.com/kb/HT5634?viewlocale=en_US&locale=en_US You can only use the 64-bit Windows 8 edition.
    Respecting to your processor, you may want to contact with Apple, as they may have sent you the iMac with a wrong processor

    if I install Windows 7 on iMac (what we have done many times and it works very good) does windows support the fusion drive?

    Welcome to the Apple Support Communities
    Fusion Drive is created by software on OS X. On a computer with Fusion Drive, Windows is installed on the HDD, but when you install the Boot Camp drivers, you will be able to read Macintosh HD, so it looks like it supports Fusion Drive but only for read
