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

1. Take a look at this one - http://support.apple.com/kb/TS5266.

2. You can always erase OSX and restore it from your backup to put it back that way it was. You will have to use Command+R or Command+Opt+R.

Macs with Fusion drive: How to find BOOTCAMP partition in Windows installer

Symptoms

After running the Boot Camp Assistant, partitioning the Fusion drive, and starting up in the Windows installer, you might not be able to find the BOOTCAMP partition in the list of available partitions to install Windows on.

Resolution

To find the BOOTCAMP partition, use the scroll bar on the right and scroll down to make the BOOTCAMP partition appears in the list. Select it and click Next to proceed to the next step in the Windows install process.

BC can be told to use the 600GB partition after you coalesce the small chunks into a 600GB one again and reformat it as MSDOS-FAT instead of Free Space.

The only down side to the restore is that it will rebuild the Fusion drive the old way. One option is to reinstall OSX new, and instead of a TM restore, to get you data back, use Migration Assistant and get everything back from TM backup without changing the disk layout. If you use Internet Recovery, what does the diskutil cs list show? Is it still in Checking/Offline mode?

I Am in Internet recovr now and at the moment I just want things back to normal so I can get a little work done on betatesting aan 4k update of an OS X app for a friend tonight then tackle the windows again in the morning so restore OS X and then migrate from this mornings Time machine it is.... I assume we do this before we try to put the 600 GB chunk back together as uniforms tend again?

We can destroy the CS completely and rebuild it with the first 600GB marked for Windows. How much effort is a clean rebuild?

Yes, do what you need to do. We can always rebuild as necessary.

ok i think it took about an hour to do the internet restore last time iadd to thhat the migration assistant to get the files i was working on back a lot of time

if i just run the the restore from time machine now from the internet restore is that making a huge ammount of work to start fresh tomorow? i can grab a apple usb superdrive in the morning as well to reduce the variables of this firewire chain to the old burner which is making some odd clunking noises anyway

IIt was only about an estimated 8 min to do the time machine restore it is running now with 2 min remaining so that thunder bay 4 external drive box is fast anyway... Once more we will try it with you tomorrow with a new sub SuperDrive the noise from this old FireWire 400 burner has me wondering if it might be part of the problem

you have the patience of Job for putting up with me through this. And I am most great ful.

see you tomorrow when I get back from portland with the drive

and we are back to our restore point from this morning
