I have been trying to intall the windows 10 software on my 2012 macbook pro using bootcamp assistant with the newest OS. The downlaod and instalation goes as planned but when i partition my disc it gives me an error message- Disk could not be partitioned due to an error, please run First aid in disk utilities. After doing so it says that /dev/disk0s2 could not be verified completely. How do i fix /dev/disk0s2 ?

Post the output of
sudo fsck_apfs -n -l /dev/rdisk1
Can you run
mount -v
and post a photo?
Can you run
umount -a
and post the output? If this does not work, we may need to install macOS on an external disk, and try to repair the internal disk.
As Lawrence Finch mentions,
Turn on your Mac, then immediately press and hold Command-R to start up from macOS Recovery.
Also,
These steps replace the Command-S method, which doesn't work with the recommended settings on current Mac computers.
Start up your Mac in single-user mode - Apple Support shows a different sequence, which you can also try.
A 2012 Mac should use the Command+S method, and show a black-and-white Terminal console.
Please be aware that APFS corruption can occur and is much more frequent. Apple Store may be able to fix it, but it can come back.
Please report back after your visit to the Apple store.
You actually have to start in diagnostic mode (Hold CMD+R until the Apple logo appears).
Check if you can unmount disk1, using
umount /dev/disk1
and check if it is still mounted. I have seen issues with APFS. We may end up installing macOS and on external drive to make it work properly.

There seems to be a syntax error in the entered command. The photo does not show me the '-- k'.
It should be entered as
fsck_apfs<space>-s<space>-o<space>-y<space>/dev/rdisk1
where <space> is the space character.
Please retry.
I actually did this, it did not result in solving my bootcamp issues.
I deleted the internal harddrive with all the software: including bootcamp.
I wouldn't suggest it, its a time consuming approach for a solution that probably needs a technical fix.
*Also you typed umount -a*
You would do it by erasing your drive through the command + r reboot and then instal the macOS using time machine
It doesnt let me run that command because the disc is mounted. I tried unmounting it in disk utilities but its greyed out.
ill show the result in 12-24 hrs
Bootcamp can't partition my disc.
