There are three options, Continue is to mount and continue to the next step; Read-Only is mounted as read-only, which is more secure, sometimes when the file system is corrupted, read-only mode will prevent further damage to the file system; Skip is not mounted and enters a command window mode. Here we choose Continue.

At this point, the system has been mounted to / mnt/sysimage. Next, enter enter and enter chroot / mnt/sysimage to enter the administrator environment.

Tips: actually, you can change the password of root in rescue mode. This rescue mode is very similar to the windows PE system. After running chroot / mnt/sysimage/, ls sees that the directory structure is the same as the directory structure on the original system. That's right! The current environment is exactly the same as that of the original system. You can type exit or press Ctrl + D to exit the environment. Then you can take a look at ls.
