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
✓
Reboot and edit GRUB to append 'init=/bin/bash' to the kernel line, then boot to a shell, then remount root as read-write, then change root password and reboot.
Root password recovery involves booting into single-user mode and remounting root as rw.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Reboot and edit GRUB to append 'init=/bin/bash' to the kernel line, then boot to a shell, then remount root as read-write, then change root password and reboot.
Why this is correct
This order is correct because you first interrupt the boot process to add the init parameter, then boot into a shell, then remount root as rw to allow password changes, then change the password and reboot.
- ✗
Change root password, then remount root as read-write, then reboot and edit GRUB, then boot to a shell.
Why it's wrong here
This is incorrect because you cannot change the password without first booting into the recovery environment and remounting root as rw. Also, editing GRUB after booting is not possible.
- ✗
Reboot and edit GRUB to append 'init=/bin/bash', then remount root as read-write, then boot to a shell, then change root password and reboot.
Why it's wrong here
This is incorrect because remounting root must happen after booting to the shell, not before. The shell from the init parameter is needed to run the mount command.
- ✗
Boot to a shell, then reboot and edit GRUB, then remount root as read-write, then change root password.
Why it's wrong here
This is incorrect because you must edit GRUB before booting to a shell with the init parameter. Booting normally then editing GRUB after boot is not possible.
