I windows the updating of a bios is easy as fuck, in linux you get bad advise all the time. I have an MSI B450 Tomahawk Max 2 and I've rebooted likely 30 times before I said fuck this shit and did it my way which worked right the first time.

The Youtube assholes are all saying you must rename your bios file to MSI.ROM "do not do that".

What worked for me was first download Unetbootin. Then put a usb stick in a usb port "make sure it's a smaller size, 16 or 8 gb is best.

Now start Unetbootin and at the top choose FreeDOS for that, then at the bottom find your usb stick you know is the blank one, use gparted to find if it you are unsure is what I did.

After you run Unetbootin I'm assuming you've downloaded your bios in a zip file. Right click and find just the bios only and extract it into the usb stick but not in a folder and don't unzip the folder the bios in the zip file is located in.

Now just reboot and update by hitting a key or like my it is in the bios itself and reboots into the flashing utility.

Very good tips. I think MSI had many complaints from Linux users regarding BIOS updates in the past, mostly due to silly decisions like issuing updates as windows .exe files only.

Now get this when you uncheck the legacy usb support a linux usb stick that is bootable is not listed. It took me almost an hour since I changed that a week ago to guess and try checking it again.

Amazing it stops a linux distro on bootable usb to not boot, if it's because of the fat32 though the usb is 3.2 version one on a usb 3.2 port seems fucked up since it should be the hardware on the port not the software on the stick. It seems that a non legacy usb port should run anything but if you're using MSI their logic is not quite right anyways it seems or AMD is garbage with huge marketing.

I'm kicking myself for not buying an Intel setup with a cpu with graphics onboard. I could have gotten it for less since I ended up getting an nvidia card that runs like shit with the blob driver it's less useful than the built in Intel CPU graphics and a hell of a lot more bullshit to put up with.
