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
✓
Check the boot order in the BIOS configuration.
The error indicates that the server cannot find a bootable device. The most common cause after a power outage is a change in the BIOS boot order. Checking the boot order is a quick, non-invasive first step. Replacing the drive or reseating cables may be necessary if boot order is correct, but starting with boot order is best.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Run a filesystem check utility from a recovery disk.
Why it's wrong here
A filesystem check would only help if the error were due to filesystem corruption, not a missing boot device.
- ✗
Replace the hard drive with a known good one.
Why it's wrong here
Replacing the drive is drastic and should not be the first step without verifying other possibilities.
- ✗
Reseat the hard drive data and power cables.
Why it's wrong here
Reseating cables is reasonable but less likely than a boot order change after a power outage.
- ✓
Check the boot order in the BIOS configuration.
Why this is correct
Power outages can reset BIOS settings, changing the boot order. Verifying and correcting the boot order is the best first step.
