220-802 Question #222: Real Exam Question with Answer & Explanation
The correct answer is B: Device boot order. The most likely cause of a 'Non-bootable drive' error for a user who regularly connects external storage devices is that a USB flash drive or external hard drive was left plugged in, and the BIOS/UEFI is attempting to boot from it first (since it appears first in the boot order).

Explanation
The most likely cause of a 'Non-bootable drive' error for a user who regularly connects external storage devices is that a USB flash drive or external hard drive was left plugged in, and the BIOS/UEFI is attempting to boot from it first (since it appears first in the boot order). Checking and correcting the boot order, or simply removing the external device, resolves this quickly. This is the most common and simplest explanation. Jumper settings, PXE boot, and hard drive cables are less likely causes given that the computer worked fine the previous day.
