Hi,
I am trying to install Windows 10 by Boot Camp Assistant and getting this error.
I have checked the disk in disk utility and have used the first aid.
Have turned off the fileVault.
Repaired the disk in single user command mode and given /sbin/fsck -fy.
Nothing worked
Is this because of my disk format is in apfs or is there anything I missed.
Thank your in advance.
MacBook Pro with Retina display, macOS High Sierra (10.13)
If your TM backup was created after the HS upgrade and is recent, you can use How to use Time Machine to back up or restore your Mac - Apple Support . You will need to boot into Internet Recovery and erase your internal disk and then restore TM.
Can you remove the FAT partition using DU and then re-run BCA and post any error messages? Also, post the output of
diskutil list
from macOS Terminal, before and after failures, if any.
Can you run
diskutil repairDisk disk0
and post the output?
Does the FAT partition creation complete successfully?
Can you boot from the OSXESERVED and try to install Windows? Disconnect all external storage to avoid installation issues.

These are the links I saw for doing this.
If I do this is it safe? Or is there any possibility I lose my settings data?

The volume should be OSXRESERVED. You may have to use disk0s6 instead. If the installer starts, select the BOOTCAMP partition as the destination and follow prompts.
and how can I switch back to MacOS?

Can you manually create a FAT partition either via Disk Utility or diskutil command?
Are you familiar with the 'bless' command? See Setboot? Formerly bless? Command line OS switching? for reference.
I have removed the FAT partitions which is created. And started BCA
Before running BCA diskutil list is
While partitioning the main drive
After downloading and installing windows support softwares
And After this point only I am getting this error

You have an error before the last line. Since you are using a 2015 Mac, which only supports EFI, use systemsetup instead of bless and test.
Post the output of
sudo systemsetup -liststartupdisks
Here is an example...
sudo systemsetup -liststartupdisks
Password:
/System/Library/CoreServices
/Volumes/BOOTCAMP/WINDOWS
It is a one-time setup to install Windows. Once BC drivers are installed you can switch back and forth.
MacOS-to-Windows -> System Preferences -> Startup Disks
Windows-to-MacOS -> Bootcamp Control Panel -> Restart macOS or How to switch between Windows and macOS in macOS High Sierra - Apple Support .
I just read this discussion
Bootcamp partitioning error in macOS 10.13
I have Time Machine Backup and I dont know how to delete this entierly and run BOOTCAMP.
Is there any specific steps do I have to follow?
Yeah I can do that, But on opening Boot Camp Assistant it is showing only the main drive and can partition only on that.
