Question
The first 446 bytes of the Master Boot Record (MBR) on station1 are damaged and you are not able to boot the system. You have the /dev/sda3 disk partition as the /boot file system. You are in the rescue environment. You tried the grub-install command but you are not able to fix this error using this command. The grub-install command takes a long time to execute and then displays the following message: "Probing devices to guess BIOS drives, This may take a long time." What would you do to recover 446 bytes, without using the grub-install command?
