cannot install windows, boot camp keeps failing

HI!!

Actually i just wiped my computer and reinstalled MAC OSX AND IT WORKED!!!

I am typing this in windows..

I guess it was just simpler than I thought which makes me wonder why I didn't get this easily working when I tried before I guess I didn't wipe the HD correctly.

I just erased my disk in disk utility, and installed mojave fresh then instantly installed bootcamp and it worked... Now I can simply restore the files and applications needed from my time machine back up...

Thanks so much for your help...

:-)

Hi I am new to Mac as I grew up with MS DOS and Windows. I do not know what you mean by trailing "/".

I have put this input into the terminal these are the results:

Hi thank but are you sure that these snapshots are the problem? Because this problem has lasted a long time, way before today. This always happens when I try to install windows.

I am pretty sure we tried this before, deleting the snapshots and it did not help.

I will try it again.. But I will not lose any information from my Time machine?

Also why would these create an issue with partitioning my disk?

I really want to understand the file system better on mac os x as I am an advanced user on ms-dos based systems which seem much simpler to me. I do not understand why on mac osx there are virtual drives within virtual drives...

I read somewhere that older macs like mine are prone to some file system error that makes boot camp fail.

It seems this way as even after completely reinstalling the OS we still could not get boot camp to work and we had to use Terminal to partition, then boot camp to finish the job.

I will try deleting those snapshots...

I did not run this previously...

Ds-MacBook-Pro:~ d$ fsck_apfs

usage: fsck_apfs [ [-q | -n | -y] [-l] [-s] [-S] [-o] ] device

    -q      quick check if the superblock and checkpoint superblock are valid.

    -n      verify only (answer "no" to questions)

    -y      always repair (answer "yes" to questions)

    -l      live fsck (lock down for verify-only)

    -s      print space verification summary

    -S      skip iteration of snapshots, although no repairs can be made.

    -o      repair overallocations; please do not run an older fsck_apfs on newer systems with this option

I just tried to partition it within Disk Utility to create a MS-Dos partition and this also failed!! :(

I don't understand why its so ridiculously complicated and no one seems to be able to help me. Or even understand what the issue is. I had to be on the phone with several tech people then they escalated so I could speak with an engineer and they had to talk me through doing this all in Terminal and it was the only way it worked!! :(

Makes me wanna get a pc again....

it says there is not command "delete"

I used some software to clear my snapshots but it just gives the same error when I try to partition

yeah I am sure I did this when I was having issues a couple years ago and it still didnt work I guess I was not wiping it right? anyway you are most kind for your time..
