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.

Received error on first command.

Started CoreStorage operation

Mounting disk

Could not mount disk1s4 with name (null) after erase

As I mentioned earlier, I already removed the Bootcamp partition in Disk Utility. Could this be why this command is failing?

Just in case it helps....here is the current diskutil list and diskutil cs list:

disk1s4 shows up as HFS, but at the same time it is in the CS, which is not correct. Can you run Disk Utility and choose Repair?

Run mount -v . Here is an example from my machine.


mount -v

/dev/disk0s2 on / (hfs, local, journaled)

devfs on /dev (devfs, local, nobrowse)

/dev/disk0s4 on /Volumes/rMBPBCMP (ntfs, local, read-only, noowners)

map -hosts on /net (autofs, nosuid, automounted, nobrowse)

map auto_home on /home (autofs, automounted, nobrowse)


Is disk1s4 mounted? Can you try removing disk1s4 from the CS volume when booted in Internet Recovery (not local Recovery).

Mar 19, 2015 8:00 AM in response to Loner T

This is what I get for mount -v


/dev/disk2 on / (hfs, local, journaled)

devfs on /dev (devfs, local, nobrowse)

map -hosts on /net (autofs, nosuid, automounted, nobrowse)

map auto_home on /home (autofs, automounted, nobrowse)

/dev/disk4s2 on /Volumes/My Book (hfs, local, nodev, nosuid, journaled)

/dev/disk3s1 on /Volumes/WININSTALL (msdos, local, nodev, nosuid, noowners)

How can I tell if it's mounted? I'm not sure how to remove it from CS in Internet Recovery mode. Would that be a terminal command?

If it helps, this is what I see in Disk Utility. The second Macintosh HD is greyed out. Not sure why.

Restarted into Internet Recovery. Went to Terminal, ran diskutil cs list. Oddly, disk1s4 was not present. Decided to try Disk Utility, received error that there was a disk missing from the Fusion Drive, which it offered to fix. Clicked fix. Ended up with a Macintosh HD with a Macintosh HD and greyed disk1s4 partition. Also a Drive 2 with OS System on it. Could not merge any of them in Disk Utility, even though it gave me the minus for disk1s4. Restarted and computer no longer boots. Get a flashing folder icon.

Mar 19, 2015 10:22 AM in response to rogerfrommission viejo

Your DU repair rebuilt the CS and generated new UUIDs. I will only mention the leading few character/digits. You will need to take the 'full' values and put them in commands (1 and 2) as appropriate.


1. Delete CS LV - diskutil cs deleteVolume A4F4...

2. Delete CS LVG - diskutil cs delete 0CC83...

3. Erase SSD - diskutil eraseDisk jhfs+ SSD disk0

4. Erase HDD - diskutil eraseDisk jhfs+ HDD disk1

5. Create a new CS LVG - diskutil cs create OSX-LVG disk0s2 disk1s2

6. Create a new CS LV - diskutil cs createVolume <EnterUUIDofLVGFromStep5> jhfs+ "Macintosh HD" 100%

7. Run TM Migration.
