So actually I used the ‘OS X Recovery Disk Assistant’ ( ) in the end and installed the Mac OS over the Internet.Ĭreate a Windows 8 USB install drive ( ) Note that if you have a problem booting from the stick with a BOOT/BCD error make sure you completely reinitialized the stick using Disk Utility’s “Erase” function to create a single FAT32 partition, then try the Win7 USB/DVD tool again. However for some reason I wasn’t able to get this to boot, kept getting that ‘no entry’ symbol. Ideally, create a Mountain Lion 10.8.2 USB install drive ( ) My solution was to delete all the existing partitions, repartition the 3TB drive so that the FAT32 one is at position 3 (so that’s good for the MBR) and starts and ends within the 2TB limit, and then to recreate the Fusion Drive using the rest of the disk. The two issues with this are first that the FAT32 partition at the end would be in the 5th position (and MBR only supports four partitions) and second that the FAT32 partition ends beyond the 2TB boundary, which is also not possible with MBR. The problem is that when the EFI boots up a Windows operating system it exposes an MBR-style partition to Windows by mapping the GUID partitions into the MBR space.

The BCA normally makes some space at the end of the “disk” (either Fusion or normal) by shrinking the HFS+ partition, and then creates a FAT32 partition at the end you can install Windows into. The problem with installing Boot Camp on a 3TB Mac is due to the way the Boot Camp Assistant works, and the way the Mac EFI boots up Windows. This howto is for people who receive the Boot Camp Assistant error “Boot Camp does not support installing Windows on this Mac.” – “Boot Camp does not currently support installing Windows on a Mac with a 3 TB hard drive.”

Update: Various people asked about variants on this process, for example when you have a 3TB HDD but no SSD – check the comments for the responses

Update: Using ‘Internet Recovery’ will normally fix anything that goes wrong with this process and will return your Mac to factory default Do a Time Machine backup before starting. Warning: Following this process verbatim will wipe all data off your Mac.
