Deleted startup disk macbook
I've accidentally deleted all my disks when I needed more GB and my macbook kept telling me the disk was full even though there was nothing on it.
I've tried multiple things that I found on the internet, also with a repartition, however, since I have only one partition, it doesn't work.
Anyone here who can help me? Or is this a lost case? ...
MacBook Air 13″, macOS 11.6
