Bootcamp installation failed

Question

Hello,I tried to install win10 via Bootcamp twice and now the Bootcamp assistant is stuck in a loop with the same error message.The startup disk cannot be partitioned or restored to a single partition.The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows.Unfortunately I cannot delete the partition using the Disk Utility.Many thanks in advance for any help.Regards, DirkMacOS Mojave Version 10.14.1MacBook (Retina, 12-inch, Early 2016)/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         313.0 GB   disk0s2   3:       Microsoft Basic Data OSXRESERVED             8.0 GB     disk0s3   4:       Microsoft Basic Data BOOTCAMP                80.0 GB    disk0s4   5:                  Apple_HFS Ohne Titel              98.8 GB    disk0s5/dev/disk1 (synthesized):   #:                       TYPE NAME                    SIZE       IDENTIFIER   0:      APFS Container Scheme -                      +313.0 GB   disk1                                 Physical Store disk0s2   1:                APFS Volume Macintosh HD            167.8 GB   disk1s1   2:                APFS Volume Preboot                 46.9 MB    disk1s2   3:                APFS Volume Recovery                512.4 MB   disk1s3APFS Container (1 found)|+-- Container disk1 A4A5353B-33AE-4784-9C8E-FD386A410D45    &#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;&#x3D;    APFS Container Reference:     disk1    Size (Capacity Ceiling):      312999997440 B (313.0 GB)    Capacity In Use By Volumes:   169676042240 B (169.7 GB) (54.2% used)    Capacity Not Allocated:       143323955200 B (143.3 GB) (45.8% free)    |    +-&lt; Physical Store disk0s2 5CDDD98C-A189-43D8-8786-9F1B48332400    |   -----------------------------------------------------------    |   APFS Physical Store Disk:   disk0s2    |   Size:                       312999997440 B (313.0 GB)    |    +-&gt; Volume disk1s1 41C90DC9-A2B6-37C2-97F6-090A97122AB8    |   ---------------------------------------------------    |   APFS Volume Disk (Role):   disk1s1 (No specific role)    |   Name:                      Macintosh HD (Case-insensitive)    |   Mount Point:               /    |   Capacity Consumed:         167898812416 B (167.9 GB)    |   FileVault:                 Yes (Unlocked)    |    +-&gt; Volume disk1s2 7BAC577F-0C34-4F0C-8176-8191EDFEDFE2    |   ---------------------------------------------------    |   APFS Volume Disk (Role):   disk1s2 (Preboot)    |   Name:                      Preboot (Case-insensitive)    |   Mount Point:               Not Mounted    |   Capacity Consumed:         46899200 B (46.9 MB)    |   FileVault:                 No    |    +-&gt; Volume disk1s3 C3065903-4937-4624-AD79-7DA00516B837    |   ---------------------------------------------------    |   APFS Volume Disk (Role):   disk1s3 (Recovery)    |   Name:                      Recovery (Case-insensitive)    |   Mount Point:               Not Mounted    |   Capacity Consumed:         512389120 B (512.4 MB)    |   FileVault:                 No    |    +-&gt; Volume disk1s4 C3F226AA-C31E-41B6-BD71-4F5CCE59D500        ---------------------------------------------------        APFS Volume Disk (Role):   disk1s4 (VM)        Name:                      VM (Case-insensitive)        Mount Point:               /private/var/vm        Capacity Consumed:         1073762304 B (1.1 GB)        FileVault:                 No

I followed Loners suggestion carefully again, but now I had to adjusted the drive name accordingly and everythings went smooth.Thank you Loner :-)But unfortunately now I got stuck in the Win10 Bootcamp setup, as I cannot accept the license agreement, because the popup windows is to small and the tick boxes and buttons are not visible.

deekee62 · Answer

Rebooting did the job, as now there is no licence agreement dialog box displayed anymore.

Excellent. Please remember to backup macOS and Windows.

deekee62 · Answer

I hope Time Machine is sufficient..

Loner T · Answer

You should use a separate disk for NTFS/Windows backup. TM does not backup Windows.

Thanks for replying, well then I will use Acronis which served me nicely during the past :-)
