    Jmoney, how was your results? Did you succeed? Do you know if the Fusion Drive is active in your OSX partition?

    This blog post has a slightly different way to do it that preserves the Fusion and doesn't need two separate HFS - http://dice.neko-san.net/2012/12/how-to-install-boot-camp-on-a-3tb-fusion-drive- mac/

    Realize that Windows is on the HDD in this example. It's not on the Fusion drive.

    Thank you for helping with this issue . It worked for me. The only thing different that I did - I have used disk utility to partition the drive. Thank God I did not get the fusion HD otherwise it would not have worked. The link to the bootcamp was what I needed.

    It seems rather strange that it is possible to be done and still Apple does not support the issue.

    I have talked with Apple support and every single one of the tech support guys were not able to give a solution to the issue.

    Thank you again. This made my day.

    Cheers

    It's not only not supported, it's not recommended. And for good reason.

     

    To support drive capacities greater than 2TiB with Boot Camp, Apple will need to support booting Windows in EFI mode. Currently Macs boot Windows in BIOS mode. BIOS requires an MBR partition scheme, which is limited to 2TiB disks.

     

    There is an enormous 36 page thread on this subject in the Boot Camp forum, littered with people who have lost data as a result of, among other seemingly innocuous things, Disk Utility allowing them to add a 3rd partition to Boot Camped drives. This has to do with the inherent fragility and ambiguity of hybrid MBRs, used by Boot Camp.

     

    All Boot Camp users, in particular those using the work around for unsupported configurations in this thread, be extra vigilant with making backups of both environments. And never resize any volume with OS X Disk Utility, or a Windows based resizing utility. Only use utilties that explicitly support Boot Camp, or you will experience data loss.

     

    Instead, I recommend anyone who actually cares about their data, to use a virtual machine instead of Boot Camp.

    Keep your backups up to date, decide how much you want to lose (a day, a week etc) and backup accordingly.

    Thank you for the insight.

    I am sure Apple has a very good reason for not supporting the bootcamp on a 3TB drive.

    However it would have seemed fair for them to warn their customers; if you choose a 3TB you won't be able to use bootcamp. Instead they choose to bag the money and play stupid every time someone asks their tech support about this issue.

    After 90 days from purchase one has actually to pay to listen to their elucubrations.

     

    Anyway thank you for the warning. I was  not going to resize the drives once all finished anyway.

    I am hoping I am going to get what I payed for. The Senior Tech Supervisors I have talked at Apple told me that indeed advertising Win install on Mac Computers was a big selling point.

     

    I am pretty sure Apple is not going to deal with this issue. It is not their style. Hope they'll prove me wrong.

     

    Cheers

    Did you buy one without checking, or is this a general complaint?

    Yeah, I'm finding nothing at all on Apple's site indicating Boot Camp won't work on certain configurations. If I configure an iMac with a 3TB drive, I'm not flagged at all of a feature loss. I also don't find such a warning on the Boot Camp specific section of Apple's web site. Or in the Boot Camp FAQ, or in the System Requirements.

     

    However, I don't see anywhere in Mac sales information online that even mentions Boot Camp. It's not a listed feature at all. It's not in iMac Features, Design, Performance, Built-in Apps, or Tech Specs.

     

    and play stupid every time someone asks their tech support about this issue

     

    I think that's a valid criticism. This is not rocket science. Boot Camp Assistant is clearly engineered to not run on disks over a certain size, so tech support should be very aware of this issue right off the bat.

     

    I am hoping I am going to get what I payed for. The Senior Tech Supervisors I have talked at Apple told me that indeed advertising Win install on Mac Computers was a big selling point.

     

    The thing is, they aren't really advertising this, that I can see from online. Maybe it's different in the physical stores. But in any case,

     

    I am pretty sure Apple is not going to deal with this issue. It is not their style. Hope they'll prove me wrong.

     

    Unclear. I expect that the way Apple will bring support for large drives, it will be a Windows 8 only thing, because they'll also move to only EFI boot support at the same time. So, sorta like how they dropped Windows XP support entirely when they started supporting Windows 7, I expect a clear separation between Windows 7/BIOS/<2TB drives and Windows 8/EFI/>2TB drives. Hackers have had a lot more difficulty getting Windows 7 to EFI boot on a Mac, than Windows 8. I suspect Apple will prefer the easy path.

    I first became aware of the issue when I ordered my 27" online.  Since the Fusion drive was new I wanted to see what they said about it so I selected "Learn more" under the Storage area.  The Boot Camp limitation is listed there.

     

    However, I, too, believe Apple should make this current limitation a prominent part of their tech specs and certainly it should be a warning that is displayed if one orders a 3TB drive.

    Aha. Yeah if you click on Learn More in the online store configuration page, before clicking on "Add to Cart" there is this light gray text on a light gray background:

     

    Note: Boot Camp is not supported on the 3TB hard drive at this time.

     

    The technology exists to flag this section with that warning upon clicking any 2+TB drive option for any computer. That's what they ought to do, in my opinion.
