Bootcamp Troubles - MacBook Pro Mid-2015 running Mojave 10.14.2

Kind-of at a loss at what has caused my issue. It's been resolved after I reinstalled OSx using APFS unencrypted, but not sure why or how.

This is the output of pre-bootcamp work.

This is the output of post-bootcamp work.

Furthermore, I now have TWO Window's options in the boot GUI. (EDIT: After restart, I only have one)

Correct. When APFS initially came out, Bootcamp was incompatible until they updated. I'm not sure what version that it became compatible, but I do know I'm using 6.1.0. In this version, you only have two options unlike previous versions: download windows support software or use bootcamp assistant, which builds the groundwork for Windows. There isn't an option to build usb media or any of that like previous.

Regardless, I'll post the steps I took to somehow resolve my issue so that others may try what I've done.

Ran Bootcamp and returned with an error pointing to errors on the hard drive. Ran disk utility and saw there were partitions made by Bootcamp when it failed. I removed them and restored the drive to a continuous APFS before running First-Aid. It returned there were errors and that I had to boot into recovery mode and use Disk Utility there.

Shut down and pressed power with CMD-R pressed. Used disk utility to perform first aid on the drive and came back with the drive being okay. Booted normally and attempted to use Bootcamp again. It repeated the first attempt. I removed the partitions that it created again and did research.

Found this article: Attempting to fix using diskutil and used this method. It returned that the drive was okay just as CMD-R Disk Utility did. I tried Bootcamp again and it failed a third time. I resorted to doing a clean install of OS without total file removal. (CMD-R, install OSX) No change in bootcamp behavior.

I then resorted to a Clean install of Mojave through recovery with file removal. Erased the complete disk and installed OSX. My first attempt at reinstalled performed it using APFS Encrypted as I had initially set my Mac up with before. After doing this, I ran diskutil and confirmed that there were no errors present again using the CMD-S method. This yielded no other results.

I read this article on four causes to common bootcamp issues and decided that if FileVault may have been problematic, then perhaps encryption was the culprit. I did yet another clean install, this time reformatting to APFS unencrypted. Installed OSX and ran diskutil to check for errors. None displayed. Bootcamp installed without error this time.

Had bootcamp not installed I was going to follow these two articles and attempt them.

Clean install of Mojave using USB key

Clean install of High Sierra using USB key AND Article containing an active High Sierra link

It seems that somehow it was resolved. Although, it's boggling as I had previously installed bootcamp with the exact same setup that I was attempting initially. I had removed it using bootcamp because I needed more space on OSX.

Loner T- In my particular situation, Bootcamp only told me that it could not creation a partition because it needed a whole drive without partitions. It wouldn't even remove what it had done previously. It was quite odd behavior.

Hi Kappy!

Either that information is incorrect or one of us have misunderstood. I've done multiple bootcamps with APFS being under Macintosh HD. Bootcamp has always partitioned Macintosh OS on a APFS format and set aside a FAT32 partition for windows installer to convert to NTFS. I've never run into that issue before.

On my particular problem: I FINALLY got Bootcamp to run by clean install with an unencrypted APFS format. I'll post the results and the end result of diskutil
