LPIC-1 System Architecture Practice Question
During the boot process, the system stops at a GRUB prompt. Which command should be typed to continue booting?
⚠ Common exam trap
A common misconception is that typing 'exit' or 'quit' will resume the boot process, but in GRUB, only 'boot' triggers the actual kernel execution.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
boot
The 'boot' command at the GRUB prompt instructs the bootloader to load the selected kernel and initramfs, then transfer control to the kernel to continue the boot process. This is the standard way to proceed from the GRUB command-line interface when the system halts at a GRUB prompt.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
quit
Why it's wrong here
`quit` is not a recognised GRUB command, so typing it produces an unknown-command error and the prompt remains. It is tempting because `quit` exits many interactive utilities, and would be the right choice for leaving applications such as `less` or a database client, not for loading a kernel.
- ✗
start
Why it's wrong here
`start` is not a valid GRUB command; GRUB loads an operating system with `boot`, so the prompt persists. It is tempting because `start` launches services in Windows shells, and would be correct there for initiating a process, but GRUB's boot loader requires `boot` to transfer control to the kernel.
- ✗
exit
Why it's wrong here
GRUB's `exit` leaves the command shell and returns to the previous boot stage or reboots, so it cannot load a kernel from the prompt. It is tempting because `exit` terminates interactive shells generally, and would be correct for quitting a GRUB menu editor subshell rather than resuming a stalled boot.
- ✓
boot
Why this is correct
At the GRUB prompt, the boot command instructs GRUB to load the configured kernel and initrd and transfer control to the kernel, continuing the boot process. Other commands such as ls or set merely inspect configuration and do not initiate loading, so boot is required to proceed.
