From your post I see its M70 BIOS. Your HP system must be a HP Zbook.

You can check your BIOS version by typing msinfo32 from the run prompt, and can identify the model name and BIOS version of your system.

Go to the below HP Support Link for downloading the respective software for your device and download the previous BIOS version which you need from the link in there.
