No bootable devices found
Latitude 7280
No bootable devices found after Dell firmware update was automatically installed. Have run F5 onboard diagnostics ( no issues) and checked setup settings on F2 - restored default, not in Legacy ( issues for previous posters)

Unplug the system, remove the base cover and disconnect the main battery from the system board. Hold the power button for 30 sec.
Reassemble and try again.

@ejn63 disconnected battery but no success unfortunately Message “ time of day not set” “ invalid configuration information”. I reset date but not sure how to proceed. Screen back to the “No bootable devices found, with F1 F2 F5 options” Appreciate your help - new to this

If that happens, your reserve battery is also dead. If you can get into system setup (F2 at powerup), does it see a hard drive or SSD?

In F2 I can see settings. Under general/ system information it has memory information and Processor information. I don’t see mention of HDD or SSD
