The correct answer is B. An incorrect boot sequence was set in the BIOS. After imaging a server from the network, the BIOS boot order may still prioritize PXE network boot over the local hard drive. Correcting the boot sequence to boot from the HDD first resolves the 'Operating system not found' error.

Troubleshooting

Question

A server administrator is installing a new OS on a server using an image from the network. The server administrator successfully connects to the network and applies the image. Upon reboot, the system displays the following message: Operating system not found. Which of the following is the MOST likely issue?

Options

  • AAn incompatible hard drive was installed.
  • BAn incorrect boot sequence was set in the BIOS.
  • CIncorrect patches were applied to the system.
  • DAn incompatible OS was used.

Why each option

After imaging a server from the network, the BIOS boot order may still prioritize PXE network boot over the local hard drive. Correcting the boot sequence to boot from the HDD first resolves the 'Operating system not found' error.

AAn incompatible hard drive was installed.

An incompatible hard drive would have prevented the image from being written successfully in the first place, and would typically produce a hardware detection error rather than an OS-not-found message on reboot.

BAn incorrect boot sequence was set in the BIOS.Correct

During a network-based OS deployment, the BIOS must be configured to boot via PXE to reach the imaging server. After the image is applied and the server reboots, if the BIOS boot order still places the network interface or another non-OS device before the local hard drive, the system will fail to locate the installed OS and display 'Operating system not found'. Correcting the BIOS boot sequence to prioritize the local HDD resolves the issue.

CIncorrect patches were applied to the system.

Incorrect patches applied post-imaging would cause OS-level errors after a successful boot, not a pre-boot failure indicating the operating system cannot be located.

DAn incompatible OS was used.

An incompatible OS would typically fail during installation or produce errors after the OS begins loading, not a pre-boot 'Operating system not found' message following a successful image transfer.
