An administrator needs to temporarily modify the kernel command line for a single boot to troubleshoot a driver issue. The system uses GRUB2. What is the most efficient way to do this without making permanent changes?

Use the 'grub-set-default' command to set a new default entry with the parameter.

Edit the 'linux' line in /boot/grub/grub.cfg directly and reboot.

Press 'e' on the desired menu entry in the GRUB menu, edit the 'linux' line to add the parameter, and press Ctrl+X to boot.

Modify the /etc/default/grub file and run update-grub.

A system administrator is troubleshooting a boot failure where the kernel panics with 'VFS: Unable to mount root fs on unknown-block(0,0)'. The administrator has verified that the root device is correctly specified in the GRUB configuration. What is the most likely cause of this error?

The initramfs is missing or does not contain the necessary drivers for the root filesystem.

The GRUB configuration file is corrupted.
