A user tries to turn on a computer but gets the following error message: Bootable device not found. The computer had no issues yesterday. Which of the following is the most likely reason for this error?
The hard drive boot sector or partition table is corrupted. If this important metadata on your hard drive becomes severely corrupted or your drive had bad sectors, your hard drive, or at least the partition containing your Operating System (OS), will appear as an empty drive
While it's possible that the hard drive (HDD) is malfunctioning, this error message ("Bootable device not found") is more likely due to a configuration issue rather than a hardware failure. If the HDD were malfunctioning, the error would likely be different, such as "Operating system not found" or similar. Also, this happened suddenly without issues yesterday, making a malfunctioning HDD less likely.
The most likely reason for this error is A. The HDD is malfunctioning.
A bootable device not found error usually indicates that the system cannot access or detect the hard disk that contains the operating system files. This could be due to a physical or logical damage to the hard disk, such as bad sectors, corrupted partitions, or faulty cables. According to the web search results, some possible causes and solutions for this error are:
Hard drive connection issue: Check the cabling and power supply to the hard drive and make sure they are properly connected12.
Corrupt hard drive partitions: Use a Windows installation media to scan and repair the corrupt system files using the System File Checker (SFC) tool1.
Damaged hard drive: Replace the hard drive with a new one and reinstall the operating system2.
Incorrect boot sequence in the BIOS: Enter the BIOS or UEFI settings menu and change the boot order to make sure that the system drive is in the first position13.
The most likely cause for the "Bootable device not found" error is a misconfigured boot device in the BIOS. This could happen due to a recent hardware change, a power outage, or a BIOS update.
Here's why the other options are less likely:
A. The HDD is malfunctioning: While a failing hard drive can cause boot issues, it would typically result in error messages related to the hard drive itself, such as "Disk read error" or "Operating system not found."
B. The mouse and keyboard are not connected: The absence of a mouse and keyboard would not prevent the computer from booting.
D. The network cable is unplugged: The network cable is not directly involved in the boot process.
By checking and correcting the boot device priority in the BIOS, the technician can usually resolve the issue and allow the computer to boot normally.

Suppose the boot order in the BIOS is misconfigured or changed (e.g., the system is trying to boot from a network drive, USB, or an empty drive). In that case, the system will be unable to find the correct bootable device, leading to the "Bootable device not found" error. The HDD should be checked after verifying the BIOS settings.
C is possible but the question is asking for the MOST likely issue. It is far more likely that the drive is going bad than the user going into their BIOS settings and manually selecting an incorrect drive on a working computer.
No it's not more likely for the hdd to be failing. We have no history of this hdd we don't know how long it's been in operation what it's used for or anything. Also, it states that there was no previous issues this would indicate to me that boot device configuration has changed.
While a malfunctioning hard drive can certainly prevent a computer from booting, the error message "Bootable device not found" typically indicates that the system cannot locate a bootable device, such as a hard drive or a bootable USB drive.
If the hard drive were completely malfunctioning, the system might not even power on or would display specific error messages related to the hard drive. In this scenario, the computer is able to boot but cannot find a valid operating system to load. This suggests a configuration issue, such as the incorrect boot order or a missing or corrupted boot sector.
Therefore, while a hard drive failure is a potential cause of boot problems, it's less likely to be the root cause in this specific case.
