How do you do a BIOS update with USB?

I need a bios update for my Gigabyte Z590 G, I have an i9 11900k monochrome and can't get a picture can someone help me how to do a bios update (no picture). I still have a laptop from which I will load it onto a USB stick.

The current BIOS is the F4a (https://www.gigabyte.com/Motherboard/Z590-VISION-G-rev-10/support#support-dl-bios), you download it and drag it onto a stick. Then you go to the bios, there's something like "Flash Bios" or "Update Bios" under some point. You select that and then select the stick. Everything else should then go automatically.

If you try to install a BIOS on the board - well then: Toi Toi Toi!
This can only end in disaster, because there are UEFI images for this, but no BIOS images.

If in doubt, make sure that the drive on the USB stick is formatted with FAT32. Unfortunately, it is not said that all z. B. Support NTFS or EXT3 / 4.

Oh yes: If you don't get a picture, then an UEFI update is stupid and nonsensical actionism - as long as the board manufacturer does not expressly recommend it.

Much more likely is a hardware defect with "no picture" - e .g. In the monitor cable, graphics chip or display. But you won't get that fixed with a UEFI update - mainly because you don't have a picture. (Whatever you mean by "monochrome", which contradicts itself with "no picture".)

Does it work even if I don't have a picture on the pc where I want to update? Because I don't know what's going on, I just don't have a picture on the PC

Ok, you should see something. How else are you going to select the bios file?

By that I actually meant, "the auto-correction recognized it incorrectly

but a hardware defect can't actually be everything I do not think that the i9 of the 11gen is broken or the mainboard
