    Hi,

    I am running High Sierra on my MB, I am trying to do a fresh install from USB.

    I had installed Windows 10 via Bootcamp which I think is the cause of my problem.

    It is not allowing me to “-“ away the parition from the “Partition” window?

    I have been messing about so much in attempt to remove the partition back to a single HDD ie no partitions I have confused myself.

    I have got myself in a right mess so really need your help, sure you can help me resolve this.

    I’ll attempt to upload pictures of the error messages I am receiving, something along the lines of “unrecognised file system”.

    Thanks in advance!

    Regards,

    Ashley

    In the menu bar, pick view, and toggle "Show all devices" on. Then select the actual SSD and not one of the Volumes, and click "Erase". If it doesn't work either, try first erasing to FAT then to APFS or macOS extended.
    If that doesn't work either, come back to me with the output of diskutil list

    Yes, this worked, thank you so much I can’t believe I have been so silly!

    I was thinking the Disk Utility view was different to his use to look… Oh dear!

    Thank you again!

    You're welcome. I've gone through countless partitioning issues and whatnot at this point. This was fortunately one of the simpler ones. Try this on a Fusion Drive and you'll tear your head out as you have to rebuild the CoreStorage container that combines the Fusion Drive. Or try and make an extra partition when you've already got Windows installed via BootCamp. This will **** up Windows, since it's installed on an MBP scheme in hybrid mode and that can only have three partitions, which would then be macOS, Recovery disk and Windows. Add another one and the system doesn't know not to try and add it to the hybrid MBR table. This one will have to be fixed with GDISk... Anyways! Your issue is fixed, and cheers for that. Have a good one :)

    Why not just remove windows from bootcamp assistant? I suppose if you are going to wipe the entire drive then just doing so from Disk Utility makes sense..
