The message “Hard Disk Error” is displayed on the screen during Stage 1 of the GRUB boot process. What does this indicate?

A.
The kernel was unable to execute /bin/init

B.
The next Stage cannot be read from the hard disk because GRUB was unable to determine the size and geometry of the disk

C.
One or more of the filesystems on the hard disk has errors and a filesystem check should be run

D.
The BIOS was unable to read the necessary data from the Master Boot Record to begin the boot process

Explanation:
GRUB Stage 1 is before the Kernel is loaded, but after the BIOS started the bootloader.
