    You do not need to be in Recovery. Run DU and Repair. Boot in Safe Mode and boot back in regular mode and try BCA again. You may also need an SMC reset.

    did Safe Mode and got the same result.

    then did SMC reset based on the se instructions

    Resetting the System Management Controller (SMC) on your Mac - Apple Support

    it still will not let BCAssistant remove windows and Disk Utility still has Verify and Repair greyed out.

    Next steps?

    Is this usual?

    This is very unusual. Can you look at Resolve startup issues and perform disk maintenance with Disk Utility and fsck - Apple Support and try the fsck method?

    The fsck method said everything was ok

    i've realised now that i cannot be sure that anything happened with the SMC Reset but have done it again to try and be sure.

    i get a slightly different error message from BCAssistant now (below) but am still unable to remove the greyed out Bootcamp.

    Will wiping the entire hard drive help?

    Can you check Applications -> Utilities -> Console logs for any error messages? In the top right corner, type boot in the search box. You will get additional messages. Please remove any personal information before posting screen shots/logs.

     

    Can you run the following highlighted command from a Terminal and post the output? Here is an example.

    Console, 'boot' results looked like this:

    That's all. It was a shorter result than the one posted. Problem?

    Can you run repairDisk instead of verifyDisk and post the output? I have seen the RepairDisk and SMC reset done twice work much better.

     

    Can you post the output of

    Is this your old BC partition? The numbers look like they are. Based on your past comments, I assume you want to remove this partition and start over.

    as trying to recover/reinstate the BC installation appears to have failed, yes, i think starting again is the next option. However, as you have seen using BCAssistant to remove the Windows partition does not seem to work either.

     

    What should be my next step?

    In a standard Bootcamp configuration, Recovery HD is sandwiched between OS X and Windows partition. BC Assistant relocates the Recovery HD and adds the disk space back to OS X. If any other utility is used to manipulate the BC disk space, it cannot be merged back into OS X, without losing Recovery HD in this non-BCA process.

     

    If you want to pursue the manual method, Recovery HD can be recreated, by re-installing OS X.

    so reinstalling OSX seems to the only way past this impass as BCA is not able to fix it.

     

    If i use Time Capsule to bring back all my files and mac software, will it also bring the problem partition back too?

    TM/TC do not back up Windows/NTFS. Take a backup of current OS X installation. My recommendation would be to back up the current OS X installation to a different directly attached external disk via USB/Firewire/Thunderbolt, which will keep your original TM/TC intact and you will have two distinct backups. It also avoids partition pollution. TM supports multiple destinations.

     

    Once you have the complete backup, use Internet Recovery, erase your internal disk, and restore from this new backup. Verify that OS X works properly. At this point you ready to try a new BCA partition/Windows installation.
