CentOS 5.11 enters rescue mode

CentOS 5.11 enters rescue mode

I recently studied centos5.11, but I don't know what's going on. I restarted the system once, and the system failed to start normally. I tried it for half a day and said it was about to enter the rescue mode. I am a newbie, I have introduced more than 6 Versions online ,. I don't know how to do this!

Afterwards, I finally turned to a book about the introduction,

1. First, enter the BIOS and set it to boot the disc.

2. When you see boot: Enter "linux rescue"
The system enters the rescue mode,

Although it looks very simple, it is really necessary to vomit blood when I don't know!

3. Select the language, keyboard, and so on. The installation is the same.

4. You will be asked if the network is required. To fix the system, you do not need to start the network.

5. Next, go to the file system of the rescue disc and find the OS related to CentOS5.x in the current machine. A Selection box is displayed for you to select:

A. Continue // Continue to be mounted in read/write mode

B. Read-Only // Read-Only mode

C. Skip // Skip this rescue

Select Continue

6. After a while, the system will display the detected Information and Press OK.

7. There will be a shell. df should first look at the mounting situation. If an exception occurs, manually mount the partition that is not mounted.

8. After completing the preceding steps, use chroot/mnt/sysimage to convert it to the original OS environment.

9. After the installation, reboot, set the boot from the hard disk, and retrieve the disc.
