HT201541: Update the software on your Mac
Learn about Update the software on your Mac
Q: Is Bootcamp 6 been released yet ?
-
Sep 5, 2015 8:29 AMby Loner T,Delete the bootcamp partition using the OSX bootcamp assistant, and create a NEW bootcamp with Win 10.
Cybmax is suggesting removing the old upgraded installation and do a clean install, to avoid W7/W8+W10 mixed drivers.
You issue is also related to a 3TB Fusion drive, because of the partitioning used by the Mac, Windows sees a vary strange disk layout. If you can find the log for the update, it would be very helpful.

Sep 5, 2015 9:02 AMby Cybmax,If you have tried to upgrade from a CLEAN (new install) windows 8.1 install to windows 10, i guess it wont help. Was mentioning this for you to try to do a clean install of windows 8.1 first, so it was not some software/driver that prevented your upgrade to finish.
Deleting the bootcamp partition AFTER you have performed the UPGRADE, was just so that you could do a clean install after... I always recommend doing clean installs vs. continuing to use the upgraded version even tho its supposed to "work perfectly", but from experience there is always some registry information/old software laying about that clutters the system
There is so many things that could go wrong during a upgrade if you have loads of software installed, and loads of obscure error messages that makes you have to read log files and search the internet for solutions

I have taken your advise and wiped my version of Win 8.1 and tried a clean install.
Unfortunately I get as far as partitioning the disk (500GB) for BOOTCAMP create the USB, but when I get to select the Windows 8.1 .iso and enter the serial key I then get a screen saying that Windows can't be installed as the partition is the wrong format. It's MS-DOS (32) and my copy of Win 8.1 is 64bit, so how do I change the partition to the correct format ? I have tried hitting the small format button and it just wipes the partition clean

Sep 6, 2015 6:35 AMby Brodie153,Hi
I have now created a new problem for myself. I had no success in installing Win 8.1. I seem to have erased the partition but I am now left with a 500GB Free Space partition which I just can't get rid of. In Disk Utility the the minus key is greyed out and I can't extend the Mac HD to fill the space, ANY IDEAS ??

Sep 6, 2015 6:42 AMby Loner T,1. BC Assistant requires the FAT32 partition it creates to be formatted manually, after you format, you can hist Next and continue Windows installation.
2. If you manipulate the partitioning by yourself using Disk Utility, BCA and DU do not work together well. Please post the output of the following Terminal commands...
diskutil list
diskutil cs list
sudo gpt -vv -r show /dev/disk0
sudo fdisk /dev/disk0
The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.

The gap is where your disk space is. Unless you want to manipulate the disks using Terminal CLI, the following steps are the simplest/safest method...
1. Back up OSX using Time Machine - Mac Basics: Time Machine backs up your Mac - Apple Support.
2. Boot into Internet Recovery - OS X: About OS X Recovery - Apple Support.
3. Erase your internal drive (the entire outermost drive which will erase the SSD and HDD part, both) and restore from the TM backup in Step 1 - OS X Yosemite: Recover your entire system.
Please be aware that TM does not backup Bootcamp partitions.

Sep 6, 2015 8:32 AMby Brodie153,Hi
Thanks again for your help. I wish I had never begun to try and upgrade to Win 10, all was working quite well before.
Anyhow, I think I understand what you suggest. Just a couple of queries.
I have a time machine backup so no problem there. Will all of my files & settings be restored to what they are, including any other users logins on the same IMac ?
Finally you suggest erasing my SSD/HDD, what is the easiest way of doing this ?

Sep 6, 2015 8:59 AMby Loner T,Use the TM icon and click on Backup Now to get the latest files on backup. Start Internet Recovery with the spinning globe. In Recovery Console, click Utilities -> Disk Utility and erase the outermost Macintosh HD. If it fails I can provide Terminal commands. Once erased, restore from TM backup.
