Hi, I am trying to install Windows 10 on my mac using bootcamp. Everything goes fine until I have to select the drive to install it on.
Here is what I did step by step.
1. Downloaded Windows 10.iso
2. Run bootcamp assistant to create Bootcamp partition and install USB
3. Boot into windows 10 installer.
4. At this point I have to select the drive to install it on, there are seveal different partitions even though in disk utility I only see one. I select the BOOTCAMP partition and format is to NFTS. When I click next I get an error saying. "We couldn't create a new parition or locate an existing one." Out of the many paritions there one in particular seemed like it wasnt needed. It was abotu 600mb so I formated it and clicked next.
5. The installiation begins but Copying files stays on 0% then I get an error saying we could not prepare the computer for the next phase of the installation. At this point the Mac restarts into Mac OS X.
The worst part is everytime I try it messes up the partitioning of the Fusion drive so I have to boot into Internet Recovery. Use terminal to split the fusion drive then refuse it, and lastly reinstall the OS and transfer all my files back. I do not believe that this is a Windows 10 installer issue but a Bootcamp + Fusion Drive issue. I have seen tons of Youtube videos of people installing windows 10 on bootcamp with no problem.
Can anyone help me out with this? I'm going to refrain from puting any of my data back on the Mac until I can get the Windows part working right.
Update: I've enabled show all partitions in Disk Utility and found out that the 650mb partition I deleted is actually the OS X Recovery HD. I've attached a picture of my drives BEFORE the bootcamp process. What I believe the problem is, is that there are too many partitions and windows can create am additional partition that it needs to store some files. I don't know what partitions I can delete to make room for one more but I've never had an issue like this before.
