This problem can occur in the following situations:

• The disk is defective

Instructions

• Press enter to get a bash shell
• If you don’t get a bash shell, stop and wait for technical support !
• Execute:

fsck -y /dev/vda1

(Change /dev/vda1 to whatever disk it says, it couldn’t read)

This will attempt to restore the superblock from a backup

• Reboot
