More boot camp problems new 5k imac 3 tera fusion drive

there seems to be problems with Yosemite and boot camp assistant

i'm cross posting this to the iMac forum but I spent hours online with apple tech today and none of the several foks I talked to there had even seen a 5k 27" yet and my call back from Cupertino and engineering is no till tomorrow so I thought I should post here too

MMy bto 5k shipped from China sunday night and arrived in Maine this morning.... Amazing when you think about it for a bto

iinstallation and set up we're going fine and I started up boot camp assistant to create a temp boot camp while I wait for my thunder bay 4 box to take the drives for my old Mac pro when boot camp will have a1 tera SSD all to itself....

so carved off a 700 gig boot camp partition which the assistant formatted fat I then plugged is the lighting to FW adapter in a LaCie 2 tera fw 800 drive to act as a bridge to my LaCie DVD burner which uses the old fw400 cables and inserted my new shrink wrap win 8.1 retail 64 DVD and up comes the win 8 install in very tiny type in a tiny window which got a bit of a laugh out of me.

And I go through it to the point of selecting that boot camp partition and then said it could not use a fat partition and I should reformat it from the win 8.1 installer which I did and then it said it could not use and unknown partition so I said great and booted back to 10-10 and the boot camp tool to put things back and it said it could not I then went to disk tools and it also said the 3tera fusion could not be either reformatted or put back to a single partition I was on with tech support where I went up through 4 levels of support due to the 5k bto which most had no knowledge of. We tried the optioncommand r to get to DT and the same problem as did going to reinstall from the net which after a 30 min down load could not reformat either it is now kicked to Cupertino with a call back tomorrow

( At this point all I want to do is put the computer back in the condition it was in when i started with a plain Yosemite on an unpartitioned 3 tera fusion... Then deal with boot camp when it can have its own drive)

am betting it will take a Unix comand line to reformat but be aware there may be boot camp issues with my configuration

and any help here will be great fully received

iMac, OS X Yosemite (10.10)

There is a much easier and cleaner method on the new iMac 5K, because it is a full UEFI machine and Windows 8.1 is UEFI compliant. The traditional bootcamp Hybrid MBR is a travesty on such a beautiful machine.

Please see this thread - Re: Problem installing Windows (7, 8.0, 8.1) on BOOTCAMP - Mavericks.

Initializing the internal disk may not be necessary at all but Command+Opt+R and DU is needed, if you really need to initialize the internal Fusion HD.

This thread can help you initialize the internal drive - Re: Can't format former Boot Camp partition

Let us add the 2.4TB back to the CS volume...

diskutil cs addDisk 153ED13B-3675-40D1-9469-2E1A3B4167EC disk2s2

Check the CS volume again...

diskutil cs list

Here is the syntax for addDisk..

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

No, you did not. If diskutil cs list still shows "Checking" the way it was showing it earlier (from this snippet from your post), wait till it shows the LVG online. Apple needs to speed up removal/addition of disks better. If you and I are on a forum discussing, and this is still working, it is way too slow. 😉. Not going to fly in the real world.

Let this come back, when it can. Since you have the 600GB carved out, do you want to try your Windows EFI installation on the Free Space?

Oct 27, 2014 11:01 AM in response to Windshadow99

I Had same issue but more serious.. On giving up on installing windows I restarted machine and on first restarts I got the 'no go of death' on all 3 partitions all labeled Macintosh HD. Then on instructions of technical support I zapped pram and tried to do Internet recover. At that stage it was apparent that I no longer had any disk access on any drive.

the machine was fried. And has now been returned as a dos.

after wasting 2 days transferring from old machine - thankfully I have a backup on time machine

DaNger. Do not attempt to use boot camp on 3tb fusion drive it can fry your disk controller

tried all zap and restart combos even a sub recovery disk but nothing would boot after tenth restart. Now have £2500 dead paperweight.
