34. A technician completes the installation of an OS that appears to be successful. However, when the technician removes the USB drive that was used for the installation and restarts the system, the following error appears: No OS found. Which of the following should the technician do next to resolve the issue?
Answer: B
Enable UEFI devices in the BIOS.
To resolve the "No OS found" error, the technician should enable UEFI devices in the BIOS. This step is crucial because the installed operating system may require UEFI settings to boot correctly.
A) Reinstall the OS from a new ISO image.
Reinstalling the OS from a new ISO image may not address the underlying issue if the BIOS settings are incorrect. This option is unnecessary if the installation was completed successfully, as the primary problem lies in the system's boot configuration rather than the installation media.
B) Enable UEFI devices in the BIOS.
Enabling UEFI devices in the BIOS directly addresses the boot configuration that may be preventing the system from recognizing the installed operating system. If the OS was installed in UEFI mode, the BIOS must also be set to boot in UEFI mode to locate and load the OS correctly.
C) Restart in recovery mode and troubleshoot.
While restarting in recovery mode could help diagnose issues, it is not the most immediate solution to the "No OS found" error. This option assumes the OS is already recognized, which contradicts the current situation where the system does not detect any OS at all.
D) Install the storage drivers for the motherboard.
Installing storage drivers is typically done during the OS installation process. If the OS was successfully installed, this step is unlikely to resolve the issue since the problem relates to boot settings rather than driver support.
E) Reseat the SATA cable.
Reseating the SATA cable could be a valid troubleshooting step if there were physical connection issues. However, since the installation was confirmed successful, this option is less relevant than adjusting BIOS settings for UEFI compatibility.
Conclusion
Enabling UEFI devices in the BIOS is the most effective next step, as it ensures that the system is configured to boot from the correct mode that matches the installation. Other options either do not address the boot configuration directly or assume that the operating system is already recognized. Therefore, option B is the most appropriate action to resolve the error encountered.
