Product: HP ProDesk 400 G1 Small Form Factor PC
Operating System: Microsoft Windows 10 (64-bit)

We updated the BIOS on a HP ProDesk 400 G1 and now the PC will not boot into Windows 10 (shows a "inaccessible boot device" error). I see the BIOS updates have been pulled from HP.com, how do we revert to the old BIOS for this PC?

Thanks.

> shows "inaccessible boot device".

 

Updating the BIOS may have caused the "default" BIOS settings to be used, instead of the previous settings.

Check the settings related to the disk-drive, e.g., IDE/AHCI/RAID, and "legacy/secure boot"
