Windows 10 Boot Camp install won't let me install on BOOTCAMP partition on Mac Pro with SSD drive

Were you able to install Windows successfully, without any issues?

Hi Loner T and thanks for the help.

The output from the cmd is as follows:

Not sure what this cmd actually means?

Can you please start a new discussion to avoid confusion?

Please see If you see a partition alert while using Boot Camp to install Windows - Apple Support .

I have spent quite a lot of time on this and its detracting from the work I really have to do. Please issue some sort of work around!!

But is it possible to install Windows 10 on a partition created onto the fusion drive ? I dit this on my iMac but on my Macbook pro it is not possible to do so via Bootcamp, so I tried manually with the disk utility app, but still get an error. I would prefer to install Windows on it because it is impossible on an usb drive.

Actually, I managed to do it, I don't know how exactly, but I think it was a bug. Though, it should still be reproducable for everyone. I first created a partition on my Fusion Drive. Then I got into Bootcamp and checked the two last options which were "download the latest software from apple" and "delete existing partitions". Then I pressed continue and the partition I created was deleted. Then, instead of forcing me to choose an SSD to install Windows, it let me create a partition on the Fusion Drive. But during all the process my SSD was connected, because else the Macbook would detect that you have no SSD connected so it won't let you install Windows, wether it is on the Fusion Drive or the SSD. I tried to unplug it, because I thought I don't needed it anymore, but it stoped the installation and I had to do all over again, so don't unplug the SSD as long as everything is completed and you're on Windows. That's it. Hope it will still work in the future ! 😉

I have had the same problem every time I install Boot Camp with El Capitan. I solved it by doing two things:

1) Unplug all external USB drives, except for the USB volume I'm booting Windows setup from. I believe the other USB external drives that I have which are formatted for OS X are confusing Windows setup and causing it not to find the NTFS volume for boot camp.

2) Reformat the Boot camp partition with NTFS using the "Format" option from the Windows setup program

Doing both of these allowed me to click next and proceed to the windows install.

Yes. What is the year/model of your Mac and the version of Windows? Windows can also be installed on the SSD part of the Fusion drive, but BC Assistant does not support such a configuration.

Thank you. This worked for me. Saved me a lot of grief. Cheers!
