HP Spectre x360 - 13-ac033dx
Microsoft Windows 10 (64-bit)

After replacing the battery  in my Spectre x360  I now receive "boot device not found, please install an operating system, Hard disk - (3FO)".  The laptop is a 2017 model (13-ac0xx)

 

Here is what I have done so far to trouble shoot:

- Rest BIOS to defaults

- Re-seat the SSD hard drive

- Check all cable connections on system board

- Tried replacing hard drive.  Still receive same message on bootup

- Ran hard drive check in hardware diagnostics.  Says hard drive is not found (on both old hard drive and replacement drive)

- Tried booting from Windows 10 bootup disk.  Hard drive is not found by Windows.

 

I am attempting to upgrade the BIOS hoping that will solve this problem.  However without Windows being recognized I don't have an option to upgrade BIOS in any of the BIOS or UEIF diagnostic menus.  UEIF diagnostics menu is only:

- Memory Test

- Hard drive check

- Language 

- Exit.

 

Can anyone offer suggestions on how to upgrade BIOS or even UEIF diagnostics version in this situation?

 

Thanks
