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

I made a typo, just going to the first screen and checking (cut and paste 4 to 5 😟 ).


This line


5. Delete Winboot Group - diskutil cs delete 1869B0B4-B850-413D-8726-41934602250B


should be


5. Delete Winboot Group- diskutil cs delete 510FD803-3431-4C23-9BAA-1D1CA0C0B065



Please execute (this is the long string that shows up right above Winboot - check for any typos I may have made).

diskutil cs delete 510FD803-3431-4C23-9BAA-1D1CA0C0B065.


Please post the output of diskutil list when deleted.

1. Leave the SSD alone for the time being.

2. Erase the HDD - diskutil eraseDisk JHFS+ Untitled disk1

3. Partition the HDD into two parts, using Disk Utility. HDD Part1 for OSX (choose the size you want) and HDD Part2 as Free Space for Windows (with the remainder of disk space). If DU wants you to create a CS volume, click on Ignore rather than Fix, otherwise we start all over again.

4. Please post the output of diskutil list when done. (I should apologize for all the picture taking/tedious process of screen shots). Recovery does have a Safari browser which can be used to copy/paste to this discussion. You are welcome to try that method, if it reduces your efforts.

it does help but i guess in recovery only one at a time can run

In DU, click on this disk after the "ignore" button, click on the + sign. It will split it into two parts. Click on the second part at the bottom. Tab to the size box, and type the size of Windows partition you want, where it says "Mac OSX extended journaled" for the second partition, click on the drop-down list and choose free space. It will change the color to grey and tab to the next box, which will resize the two parts properly, then click on Apple. Post the output of diskutil list.


PS: so you want to give Windows 600GB, is that correct?

yes

sorry to be so slow about this
