Provavelmente, é a sua partição do sistema e você não deve excluí-la. Para determinar, verifique a saída de mount
:
$ mount

No meu exemplo, o Ubuntu está instalado em /dev/md0p5
, que é mostrado em negrito. Se você achar que seu volume também está montado em /
você definitivamente não deve excluí-lo
