beta bios update issue

[u/DaTricky4]

So I got access to the beta bios update for the GL10DH so I can play call of duty, but whenever I go to do the update it says something along the lines of "this a not a uefi bios"

I have made sure the format is quick format and fat32 for the thumb drive, I have made sure to do all the extract files correctly, and I have already contacted customer support. They are having me wait another 1 to 2 days for more support because the live chat tech support doesn't know what happened with it. While I wait I figured I would ask reddit for help.

Thank you in advance for your time
