Boot error after battery replacement

[Hkud]

Replaced my 2018 hp Pavillion battery recently. Worked well for a week. Had to hard restart once and after that got boot error. Checked bios settings and enabled legacy. Also tried resetting bios. But after saving get 'nk bootable device error'. Any suggestions?

@Hkud,

Welcome to HP Support Community,

Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue

Reset the BIOS to Default Settings: Power off the laptop, enter the BIOS by pressing Esc or F10 repeatedly during boot, restore defaults, save changes, and exit.

Check Boot Order in BIOS: Ensure your hard drive (or SSD) is set as the first boot device in the BIOS Boot Options. Adjust the boot mode to UEFI if needed, save changes, and exit.

Disable Legacy Boot: If Legacy Boot is enabled, disable it and revert to UEFI mode. Ensure Secure Boot is enabled, save changes, and exit the BIOS.

Check the Hard Drive Connection: Power off the laptop, disconnect the battery, and verify the hard drive or SSD is properly connected. Re-seat the drive if necessary.

Run Hardware Diagnostics: Power on the laptop, press Esc or F2 to access HP Diagnostics, and run the hard drive test to check for hardware issues.

Check for OS Corruption: If hardware checks out, use a Windows recovery USB to attempt a boot repair. If necessary, reinstall Windows.

Perform a System Restore or Reset: Use a recovery drive to perform a system restore or reset the system to factory settings if the OS is corrupted.

I hope these steps help resolve the issue

Hi. Tried the steps. When i do a hardware check after f2, the harddrive is not detected. Tried re seating it, but same issue.

The laptop has a 256 name m.2. Not sure if the software is looking for any other drive?

Anything else I can try please?
