Was this BIOS an update option offered by Windows update? BIOS updates are scary at the best of times, but it really troubles me that some manufacturers offer the updates through Windows updates.
But, I doubt whether this is related to or the cause of your woes.
I've seen this happen before with HP devices because the problem updates relate to HP bloatware (system and hardware checking/managing/monitoring software that is totally superfluous), stuff that I ususally blow away the moment I open any proprietary brand device.
I think you should prepare yourself for the possibility of an unrecoverable borked update process and start thinking about whether a wipe and clean install won't save you hours of further (futile) troubleshooting.
Back up your personal data, and image the existing system anyway. Then if last resort is necessary, you're ready for the ultimate sacrifice - a totally clean install using the Media Creation Tool and a Windows 10 boot USB.
