A user reports that a Windows 10 PC displays the error message “Invalid Boot Disk” during the boot process. The IT technician attempts to boot the computer and finds that the error message occurs immediately after the POST. What could be the possible cause?

• A recently installed device driver is incompatible with the boot controller.
• BOOTMGR is corrupted.
• The MBR/GPT is corrupted.
• A service failed to start during the booting process.
  

  Explanation: The message “invalid Boot Disk” could be a symptom of a missing or damaged MBR/GPT, a missing or damaged Boot Configuration Data file, a boot sector virus, a boot order not set correctly in BIOS, media without an operating system being in a drive, a hard drive not detected or damaged, or the absence of an installed operating system.
