A server fails to boot, and the administrator sees the error 'Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)'. The administrator boots from a rescue CD and mounts the root filesystem successfully. Which action is most likely to resolve the issue?

Reinstall the kernel package using the package manager to ensure the kernel image is not corrupted.

Edit the GRUB configuration to specify the correct root device using the root= kernel parameter and regenerate the GRUB configuration.

Add the 'single' parameter to the GRUB command line to boot into single-user mode and then fix the issue.

Run fsck on the root filesystem to repair any corruption that prevents the kernel from mounting it.

What is the effect of passing the kernel boot parameter `single` (or `1`) at the GRUB prompt?

It forces the kernel to use only one CPU core.

It skips the boot loader and loads the kernel directly.

It disables all kernel logging.

It boots the system into single-user mode (runlevel 1), providing a root shell for maintenance.
