"Linux system" simulating MBR sector failure and recovery

First, it is the first step to build an experimental environment before doing the experiment, and the next is to do the experiment.

The following is my experimental environment: prepare a virtual machine with a Linux system (I use the Linux6 version of the virtual machine), and the system to have two disks, that is to add a disk. The newly added disk will be partitioned and formatted before the MBR sector failure can be simulated. However, before you perform a simulated MBR sector failure, you need to back up the disk before the data is lost. The MBR sector is restored.

Partition and format the disk, if you do not understand, please see my previous write "Linux system" disk partition one of the partitions.

After the configuration is complete, enter init 6 to reboot. But after this interface, press ESC and enter to confirm.

Enter the following statement for Linux rescue.

The basic of the following is to press the TAB key and enter OK. There is one exception, however, which is specifically presented below.

The question here is, is your system going to install a network interface? After pressing the TAB key, select No in the Enter OK.

After rebooting, check. (Check to see if the SDA disk is restored.)
