I have been trying to start Bootcamp Assistant in High Sierra 10.13.6 and every time I try (and re-try) I get an error message that Bootcamp quit unexpectedly. The error detail are in the additional text.
Any help will be appreciated!
iMac, macOS 10.13
You need to boot into Internet Recovery (About macOS Recovery on Intel-based Mac computers - Apple Support) and erase the whole disk, not just Macintosh HD. Once you have erased the whole disk, you can then re-install macOS, restore you backup and then retry BC Assistant.
This is the output:
/dev/disk0 (internal, physical):

Any thoughts?

The highlighted entry is invalid. How did you get this partition on your disk? Do you have a Time Machine backup?
Not sure where that partition came from. My time machine backup is in the cloud (Apple Drive). I had to re-install High Sierra at one point from a USB installer disk when I upgraded to SSD . Do I need to get rid of the partition? If so, what is the best way to do it?
I tried erasing the whole disk as you mentioned above, unfortunately it gives me an error of:
Erase process has failed
and under details gives me three lines:
Unmounting device
Couldn't open device
Operation failed...
I tried different format types and get the same error.
Any thoughts?
This is what I get:

In your original post, this shows...
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *1.0 TB disk0
1: Apple_APFS Container disk1 134.2 MB disk0s1
2: EFI EFI 209.7 MB disk0s2
3: Apple_APFS Container disk2 999.9 GB disk0s3
but now...
/dev/disk0 (internal, physical):
#: TYPE NAME SIZE IDENTIFIER
0: GUID_partition_scheme *1.0 TB disk0
1: EFI EFI 209.7 MB disk0s1
2: Apple_APFS Container disk1 1000.0 GB disk0s2
Quit Terminal, go back to the main Recovery Console, boot normally, and check the output of
diskutil list
Do you still see an APFS Container at disk0s1?
No, I do not see the APFS Container at disk0s1 anymore, but rather the output is identical to the second posted output after I booted normally as per your instructions. Should I try reinstalling High Sierra?
You do not need to re-install macOS. Can you try to run BC Assistant?
BC Assistant can crash if the underlying disk partitions are not supported. From macODS Terminal, can you post the output of
diskutil list
In Recovery, click on Utilities -> Terminal, and post a screen shot/photo of
diskutil list internal
Yes, I was able to run BootCamp Assistant correctly, and was able to install Windows.
Thank you for your help!
Excellent!
