    I upgraded one of my Macs (the MBP 2016) to the developer beta and updated to APFS. And now I can't use Boot Camp Assistant. It says my Mac has 2 internal drives and that my drive was partitioned by something other than Boot Camp Assistant.

    I also can't boot from the recovery partition.

    FWIW, the file system is now in a container and I'm guessing stuff needs to be updated yet. Here's what diskutil list has to say. Not looking for a solution, because I've got it backed up and I can reformat jHFS+, just wondering if anyone else has noticed any of this.

    Code:
    /dev/disk0 (internal):
       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:      GUID_partition_scheme                         500.3 GB   disk0
       1:                        EFI EFI                     314.6 MB   disk0s1
       2:                 Apple_APFS Container disk1         499.3 GB   disk0s2
       3:       Apple_KernelCoreDump                         655.4 MB   disk0s3
    
    /dev/disk1 (synthesized):
       #:                       TYPE NAME                    SIZE       IDENTIFIER
       0:      APFS Container Scheme -                      +499.3 GB   disk1
                                     Physical Store disk0s2
       1:                APFS Volume Macintosh HD            133.0 GB   disk1s1
       2:                APFS Volume Preboot                 39.4 MB    disk1s2
       3:                APFS Volume Recovery                1.0 GB     disk1s3
       4:                APFS Volume VM                      1.1 GB     disk1s4

    Lets bring this up again.
    I have the exact same problem and am not able to create a boot camp partition at this point. Has anybody an idea to handle or a workaround to get windows installed on the sd card? :)

    I had the same problem. I fixed it by booting into recovery and using disk utility to delete the Apple_kernalcoredump partition and then boot camp assistant worked.

    Had this idea as well but was not sure about it, so i installed my win 10 boot camp on an external ssd and this works great even with more space :)

    How did you go about doing that? When I go into Disk Utility in Recovery Mode and click on the Apple_kernalcoredump it doesn't give the option to delete the volume. I also tried using Terminal and that did not work either.

    I just clicked on the partition and then clicked on the - button below it.

    Bootcamp in High Sierra Beta don't support modification apfs partition, so can't split it to create a bootcamp pratition.
