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

Clean install of El Capitan, I have downloaded the Windows 10 x64 ISO and run Boot Camp installer. Once you get to the screen where you select a partition, the BOOTCAMP partition can't be installed on. If I format it and try again, still no luck. Anyone have experience with this problem or a workaround for this?

Thanks,

Patrick

Mac Pro (Late 2013), OS X El Capitan (10.11.1), 256 GB SSD, 12 GB RAM

    I just did a full rebuild of my Fusion drive in Recovery mode. and Disk util rebuild it as per apple default with SSD as disk 1 and my 3TB as disk 0

     

    So i wouldn't recommend above from Loner. as i dont think Disk util will rebuild it in any other way.

    A CS PV at index 0 is fast disk designed to off-load LRU blocks to disks at index 1...n. If you have it any other way. it is invalid. Please see the IO tests at http://jolly.jinx.de/teclog/2012.10.20.fusion-drive-on-older-macs-yes.html .

     

    Diskutil will rebuild a CS anyway you want it to. Please also see OSX and Bootcamp discussion .

    You are confusing disk0 and disk1 with CS PV indices. disk0 and disk1 are based on probes by controllers to discover disks. They have no relationship with the CS index. Once a CS is built, the order of discovery may change and disk1 may be the SSD. The CS unit stores the indices and manages data block movement based on CS PV Indices, not the diskN numbering. The instructions you wrote need to account for the ordering of the fast vs slow disks. As I posted earlier, see the IO test results. You want the slower disks at index 1...n not at 0. If you have multiple SSDs, you must ensure that the faster disks have lower indices than any of the slowest disks.

     

    I have had to fix the Apple instructions over the years. Please see the links I have posted.

    I tried to understand both links you sent but I still don't follow why SSD should be always the first. Can you please write a little howto how we can rebuilt partitions so the SSD will be first? I'll try.

    How did you get Drive0: Partition 5? It should be partition 4.

     

    Can you post your diskutil list output?

    New bootcamp on iMac doesn't give you 3 choices anymore. It creates partition with windows installation. This is listed while bootcamp is preparing windows to install. Normally, 4 and 5 are not there.

    Please post the output of sudo fdisk /dev/disk0 . The OSXRESERVED being present is a good sign. Can you mount it and check what files are present?

    After disk0s5 has been created and before the installer starts, do you have the ability to run the following command on the disk0s5

     

    diskutil eraseVolume free Free disk0s5

     

    and then select it from the Windows installer.

     

    You may have to time the erase appropriately.

    So you mean before windows installer starts?

    Sure, I made watch command in terminal listing files in OSXRESERVED as you requested which blocked automatic restart.

    I do now and then try install again.

     

    Before install:

    didn't create partition, just pressed next so windows created it automatically, short after copying began, popup window throwing error appeared:

     

    "Windows detected that the EFI system partition was formatted as NTFS. Format the EFI system partition as FAT32, and restart the installation."


    Is it possible to manually create windows partitions and install windows entirely via command line? Do you have experience doing that?

    You need to format it as Free Space not NTFS. Did you use Shift+F10 in the installer? What year/model is your Mac?
