升级后，我无法再运行操作系统；它带我进入黑屏并显示：
/dev/sda2 contains a file system with errors, check forced.
Inodes that were part of a corrupted orphan linked list found.
/dev/sda2: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY
fsck exited with status code 4
the root filesystem on dev/sda2 requires a manual fsck
我也尝试过在安全模式下运行，但发生了同样的事情。
有人能建议我在这里可以做什么吗？
