Q: Issue trying to clean install Windows 10 on Fusion Drive. el Capitan.
Issue: Trying a clean install of Windows 10 via Boot Camp Assistant on an iMac 27 inch (Late2013) with 10.11.4 results in the installation taking hours (over 8 hours) and then unable to install Boot Camp updates. Basically installation taking much longer than normal and unable to install the Apple software updates or create normally booting Windows 10 Boot Camp.
Background: After slowdown issues after upgrading to 10.11.4 (with Bootcamp upgraded Windows 10) which had previously worked fine for 10 months, to the point of a hour to boot to OS X, I decided to do a clean install of my iMac with 3TB Fusion Drive.
As I was unable to remove the Boot Camp partition via BCA due to it taking forever to even load, I used Internet Recovery and reinitialised the Fusion Drive. This then required me to repair the Fusion Drive partition via DU 'fix' option which appeared to work fine. And reinstalled OS X 10.11.4 which works fine now (no delays etc.)
On trying to use BCA to create a new Boot Camp partition and a clean Windows 10 install, after downloading a W10 disk image direct from Microsoft (Win10_1511_1_English_x64), BCA downloading the software updates and selecting the desired partition, it commenced reboot and initialise the install. However the whole process was very slow, each stage taking much longer than usual, to progress. Leaving it for hours still left a blank screen or one with a rotating circle.
I tried with another USB 3 stick and also a USB 2 stick but neither made a difference.
On the last attempt I left it running over night and after 8-9 hours it eventually reached the Windows 10 desk top and the Apple Bootcamp Update launching to load the updates. However it just hung and even after 2 hours nothing had happened. Rebooting and trying again was the same.
After this I tried creating a Windows 8.0 install via BCA however it just gives a GPT error when trying to select the drive (due to el Capitan I assume?)
After four days of efforts I am at a lose as to how to get the Windows 10 onto the Boot Camp partition. I am unable even to install W8 and upgrade due to GPT error.
Any help or suggestions how to proceed with diagnosing/resolving the issue would be appreciated.
Details:
System: iMac (27-inch, Late 2013), 3,4 GHz Intel Core i5, 16 GB 1600 MHz DDR3, NVIDIA GeForce GTX 780M 4096 MB, OS X 10.11.4.
- Nothing other than keyboard and mouse attached via USB ports, along with the BCA USB stick. No other devices attached.
- Reset NVRAM, SMC and ran Disk Utility a number of times. No issue reported. Ran NVRAM reset before each attempt.
- Ran EtreCheck report which appeared OK.
- Ran Diagnostic check which returned no issue.
One detail I noticed after fixing the Fusion Drive there are now two Macintosh HD images when using option boot. Only one previously. The are named 'Macintosh HD' and 'Macintosh HD2'. I remember there being three at one time in Yosemite but that was fixed in an update.
Also, there appears to be no Recovery partition. Cmd+R launches Internet Recovery.
