How do I update BIOS on Centos?

I'm running Centos 7 on a Lenovo m83 and I can't figure out how to update the bios. I'm very new to Linux so if anyone can help me out I'd appreciate it.

I downloaded fbj9d1usa.iso from the site, threw it onto a flash drive, and now I can't figure out how to navigate to it or run it.

Some BIOS utilities allow you to flash the image directly without first booting an OS and if this option is available I would use it. If not, you need to create a bootable USB disk from that ISO. Just copying the files will not make the disk bootable. This page will probably help. It describes using dd to create a boot disk. https://workaround.org/article/updating-the-bios-on-lenovo-laptops-from-linux-using-a-usb-flash-stick/

If you are just updating the BIOS to "feel" current, please be aware that you could cause more problems than you fix, to the point that the device won't boot, so only update the BIOS if it fixes a specific issue you are having. Do make sure that there is no chance of the device losing power during the update process.

Pay particular attention to Martyn's comment.

If you're experiencing a specific problem, that a specific BIOS version update fixes, install the update.

If all's well... I'd avoid updating BIOS... That's me personally. I'd rather have my machines working, than install a BIOS update that took one out or caused subtle problems sometime in the future.
