I have never installed windows via bootcamp, I have a parallels 12 installation with a windows 10 vm

Can you boot to that drive? I'm not a Parallels user, but since its a VM machine, it doesn't partition your drive, but rather lives in a directory under MacOS. Do you maybe have an external drive plugged in name Windows?

One more weird thing to accompany the problem, I have used bootcamp assistant only to download the bootcamp drivers software for another install, never did I create a bootcamp partition, but the utility now seems broken, I only get this error no matter what I do
"The installer disc could not be found."

I really don't want to do through a clean installation if its something that can be fixed
I would really appreciate some help

As you can see from my previous message this is not possible due to the error in the Bootcamp assistant

Wild guess: Maybe when you downloaded the bootcamp drivers, OSX mounted a temporary disk image to uncompress the download, and that temporary image is still hanging around.

One way to check is to run Disk Utility and have a look at the list of mounted drives and images in the left pane.

Also, as mentioned by another poster, have you done a search for Windows folders lying around on your mac?

Nope, this is not just a mounted volume
Bootcamp had an error when downloading the drivers, then tried removing the partition it created but it was just laying around without doing anything for hours, so I just quit and now I am having this

Are you the first user?, There was Windows installed on your machine and it was not removed the right way using Boot Camp, instead only the partition was deleted leaving the windows record in the boot partition.
To fix this you need to erase the disk and not the partition and do a clean install.
Leaving it as it is will not harm your Mac in anyway.

Based on what you've said, it seems Bootcamp Assistant did indeed create a partition, then for whatever reason, things went wrong and it wasn't cleanly backed out / deleted. As Shafez said above, the small boot partition in your 500GB SSD is holding a list of boot options that claims Windows is available to boot to, and hence offering that as an option.

no external drives
when I boot to this volume I get a windows 10 recovery blue screen

I have two disks, a 512GB flash and a 1TB SSD
What do you mean by "512GB flash"? I don't think that's the right name for it. I can see from the output of diskutil you posted earlier that your mac boots from it. What sort of mac do you have?

- Create a Boot Camp windows partition and follow instructions till you reboot to windows Setup.
- Reboot back to macOS and go into Boot Camp and remove the windows partition.

This should solve your problem and remove the windows partition from boot.

Tested.

I can't
it fails every time and bootcamp stalls with a message saying that it reverts the configuration by removing the partition
I suppose this happened the first time and now that why I see a windows option upon booting

Mounted the EFI partition and deleted two folders in my case, boot and Microsoft, left the APPLE intact
Problem solved

Thank you for your help and your time
