Can't remove "Bootcamp" partition. Have tried all advice in support and community.
I created partition but didn't install Windows. There is no option in Bootcamp to delete the partition; using disk utility to either use the minus button to remove the partition or to "erase" it leads to an error message. Initially I used "erase" and selected APFS and probably "unmounted" it prior. I just checked and it's gone but I now seem to have a variety of nameless "Volumes" one of which has about 40GB used which is similar to the Bootcamp size. I think I know enough about Apple OS now to consider that a re-install of the OS is the only answer to any issue that can't be solved within a couple of minutes; I expect that there is no readily accessible information in fairly plain English of what the Disk information means?
