Retina iMac 3tb Fusion drive Boot Camp failure

Trying to install Windows 8.1 to a 1tb Bootcamp partition on 3tb Fusion drive. BCA creates the partition, Windows installer sees it, but requires formatting it, but then it can't install to it. I get an error that it can't create or see the partition. I'm assuming this has to do with BCA creating the partition someplace Windows can't handle it (past the first 2.2tb of the drive).


Here is the info requested in a previous thread.

That's correct with a Fusion Drive, only 1 additional partition can be created. The OP has already used that for Macintosh HD2.


Can I add a partition to the hard disk with Fusion Drive?

Using Disk Utility, you can add one partition to the hard disk on Fusion Drive. Once you add the partition, the "plus" symbol in Disk Utility to add additional partitions will be grayed out. You cannot partition the Flash storage


Can I add a Windows partition?

You can create one additional partition on the hard disk with Fusion Drive. You can create either a Mac OS X partition or a Windows partition. If creating a Windows partition, use Boot Camp Assistant to create it, not Disk Utility. From the Go menu, choose Utilities. Then, double-click Boot Camp Assistant and follow the onscreen instructions. For more information on Boot Camp see the Boot Camp support page.


Note: Boot Camp Assistant in OS X Mountain Lion v10.8.2 and earlier does not support 3TB hard drive configurations

Mar 17, 2015 1:50 PM in response to keg55

keg55 DU has limitations, but diskutil does not have the same limitations. On a 3TB Fusion drive, with a Hybrid MBR, you have a CS on HDD, BC, and then another part which has the remaining OSX CS part.

Using Disk Utility, you can add one partition to the hard disk on Fusion Drive. Once you add the partition, the "plus" symbol in Disk Utility to add additional partitions will be grayed out. You cannot partition the Flash storage.

The Flash can also be partitioned using resizeStack and choosing appropriate physical disk UUID. I have done this on three Minis by building my now CS. The artificial limitations of DU and its broken and undocumented features are bad form from Apple.

Good to see the disk slices cleaned up.


To add the remaining slice (disk1s5) use the following command.


diskutil cs adddisk 49E959A5-5F3C-4178-8A2D-067D2C853A96 disk1s5


Here is the help output of the command. Please post the output of diskutil cs list once you execute the addDisk command.


diskutil cs adddisk

Usage: diskutil coreStorage addDisk lvgUUID NewMemberDeviceName

Add a new physical volume to a CoreStorage logical volume group.

Ownership of the affected disks is required.

Example: diskutil coreStorage addDisk

11111111-2222-3333-4444-555555555555 disk4s2


Can you also post the the output of sudo fdisk /dev/disk1? (This will show what the current MBR) looks like.


You can now either use EFI boot and use BOOTCAMP (disk1s4) or a new Hybrid MBR can be created for the legacy BIOS installation. The Hybrid MBR can be very easily created using GPT fdisk | SourceForge.net.
