Comprehensive and Detailed Explanation From Exact Extract:
An ‘OS Not Found’ error typically indicates that the computer is attempting to boot from a drive that doesn’t contain a valid operating system or bootable partition. The presence of a USB drive might be confusing the boot order. Therefore, the first step a technician should take is to verify and adjust the boot sequence in the system’s firmware (BIOS or UEFI). It’s possible that the USB drive is being prioritized over the internal hard drive, which may cause the system to miss the OS entirely.
A . Running data recovery tools is premature before confirming boot order.
B . Repartitioning the disk would destroy existing data—this should not be done until confirmed the OS is actually missing.
D . Switching between UEFI and BIOS (legacy mode) might help in rare cases, but it is not the first step in standard OS boot issue troubleshooting.
CompTIA A+ 220-1102 Objective 1.7: Troubleshoot common operating system problems.

A bollard is a sturdy physical barrier—often a steel or concrete post—designed to prevent vehicles or unauthorized individuals from ramming into or entering secure areas of a building. It provides physical security and is commonly used outside entrances to prevent forced entry.
A . PIV (Personal Identity Verification) cards are used for identity access control, not physical blocking.
B . Motion lighting may deter activity but doesn’t physically prevent entry.
C . Surveillance records activity but cannot stop a forced entry.
CompTIA A+ 220-1102 Objective 2.4: Compare and contrast physical security measures.
