Corrupted BIOS Repair

[persona1234]

Model: HP 15s-eq2158AU

My laptop does not boot and only leaves a black screen. I have already tried connecting to an external monitor and it doesn't project. The screen did flash a few times and stated something about my BIOS being corrupted. There would be a progress bar but then it would return to a black screen, I recently tried the method of downloading the latest BIOS on the support page and creating a recovery USB flash drive. I inserted the flash drive and powered it on and the black screen still persisted. I tried it again, this time holding Windows Key + B before powering it on and with the flash drive inserted and it still didn't work.
