Bootcamp partition can't be detected after reinstalled MacOS
I reinstalled Mac OS about a month ago, and I found that there is no bootcamp in system preferences->startup disk. Boot camp assistant also does not recognize the partition and gave me an error "the startup disk cannot be partitioned or restored to a single partition". So I'm not able to remove the bootcamp partition either. How can I fix it?
