Hi,


Yes I have an iMac 5K but it did not have a fusion drive. I had a single Apple SSD and installed a separate Samsung SSD where the HDD fusion slot. I did this solely so I could install windows on a separate drive rather than partitioning...


I was not aware that I would encounter these problems?


What is the problem with the iMac and having 2 separate internal drives?


Can I resolve this by "fusing" the 2 SSD's and then partitioning them? Seem's a bit ridiculous seeing as they are both SSD's though?


Thanks Loner T.

Hi,


This is a late 2015 model. I have had a number of problems with Bootcamp.


1. When creating a windows USB it does ask for an ISO but the process does get underway. The error was something like could not copy files...


2. I was unable to download the drivers and create a USB. Bootcamp would freeze once download completed (repeatedly on different internet connections). Unfortunately after speaking with apple this is the only was I can get the newest drivers for Windows 10. The other "publicly facing drivers only support up to windows 8.1)


3. When creating the bootcamp on the second drive I received a number of errors. Errors reformatting drive, and errors copying ISO files.
4. I have managed to install windows manually, however as per point 1 this is pointless if I cannot get the latest drivers to run windows 10 from bootcamp assistant.


5. I am not sure if OS X is broken, seems to be some communication problem with OS X. I also had errors generating log files with apple on the problem. I have decided to erase all discs an re-install OS X to see if Bootcamp will run.


Do you think this is a system problem, a specific problem with bootcamp, or is putting in the second ssd playing havok with the iMacs understanding of the world?


Cheers,

1. 2015 Models do not use a USB Installer. They use an internal partition called OSXRESERVED. Please see https://help.apple.com/bootcamp/assistant/6.0/#/bcmp173b3bf2 for reference.


2. BC 6.x will download BC drivers every time you want to install Windows. It is a rather unfortunate design and a flaw, both. I sit possible to use a wired connection?


3. You can create a Fusion drive, and allocate Windows enough disk space to cover the entire disk, which will use the second disk. If you run into any issues, a diskutil cs resizeStack can be used to carve out space on the second disk.


4. The latest drivers can be manually downloaded to a USB flash drive using the following.

5. OSX (and specifically) BCA cannot deal with non-standard disk configurations. These are derived from the Mac Model Identifier. For example, your disk configuration is supported on a pre-2013 Mac Pro.

Thanks Loner T!


Most helpful, I was able to download the drivers under the action menu! It was not working when I was going through BCA prompts....


Your right. After clean install BCA will still not copy files. BCA prompts me for a Windows installer disc but I am still getting this error..User uploaded file


My plan was to download a program which will allow disk utility to partition the secondary drive into NTFS. Then install windows from windows install disc. Then I can at least install the most recent drivers I have downloaded through BCA and everything should work?


I didn't want to create a fusion drive and then partition the drive as it just seem clunky, with a lot of drive fusing and splitting?


Are there any advantages to creating a fusion drive rather than keeping them separate and following my procedure above?

Thanks, much appreciated.

From OS X Terminal, can you post the output of


diskutil list

diskutil cs list


If DU fails to erase/format the second disk, it can be manually erased. What is the version of Windows you want to install? You 2015 Mac only supports W8.1/W10 in EFI Mode. W7 and older versions are no longer supported under Bootcamp. To install W7 and older versions Virtualization engines may be an option worth considering.
