Failed Boot Camp partition and cannot remove

Hi all,

I tried to install windows through bootcamp and it went all the way and then wouldn't complete. I turned off time machine back up and a couple of other recommended things to try again and Bootcamp is telling me the drive cannot be partitioned. I then tried to remove the partition in Disk Utility using the partition method and that didn't work either. I then went back to Boot Camp and now it is saying that FileVault is decrypting and can't do anything until that is complete. Can someone please help me remove this failed partition so I can get Bootcamp running again? Happy to format if needed as there is nothing of value in OSX for me.

Thank you in advance!

My diskutil list Terminal output:

/dev/disk0 (internal):

Thanks for replying LonerT.

I tried to remove it with Disk Utility but I can't get it to work, can you please advise how I can do this properly? The - symbol is greyed out when I try to partition within Disk Utility, please refer screen shot below. Thank you

BC Assistant will not support this partition. Did you erase the Bootcamp partition using Disk Utility?

If the FileVault decryption is complete, run

diskutil eraseVolume fat32 BOOTCAMP disk0s3

and run BC Assistant and click on Continue -> Remove/Restore.
