Inaccessible Boot Device following BIOS update

HP Recommended
HP ProDesk 400 G1 Small Form Factor PC
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, how do we revert to the old BIOS for this PC?

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"
