Difference between BIOS Installer for Windows and BIOS for ASUS EZ Flash Utility?
Can't comment on Windows BIOS installer, but I actually just upgraded to BIOS 218 without any effort. I was running 217 just fine so I wasn't going to update, but Windows 10 auto installed a BIOS 218 package as part of a Windows update. I rebooted the computer and ASUS EZ Flash opened up in BIOS on restart and basically did the rest. It took all of 2 minutes. Just a preference, but after reboot, I got rid of the ASUS software Windows installed, and disabled the startup entries. Anyway, I've got BIOS 218 running smoothly. So, based on today's experience, ASUS EZ Flash is definitely the way to go. More on reddit.com

I don't want to update the BIOS at all.

I mean, it's not like I want the older version or the newer version more, but I don't want to alter anything, I don't want to risk having the update brick my laptop.

U don't want to either upgrade or downgrade.

r/ASUS on Reddit: I found an easier way to update ASUS motherboard UEFI BIOS
September 1, 2022 -

Officially, Asus lists 3 ways to update BIOS: two methods need a FAT formatted USB drive, the third method needs AI Suite 3 / EZ Update software. I've found a fourth method than needs neither a USB drive nor any Asus software/bloatware installed, and is actually the easiest to use.

My method uses EZ Flash 3 utility that is baked into UEFI BIOS, but it doesn't need a USB drive to read the new bios update file. What Asus doesn't say and what I accidentally found out it that EZ Flash 3 can read NTFS drives. You can simply download the bios file to your main C:/ (Windows) drive and update from there. Here's are the instructions in detail:

  1. Download the latest BIOS update from ASUS support page for your specific motherboard.

  2. After unzip, a .CAP file will appear, this is the BIOS update file. OPTIONAL: Move this file somewhere where it's easy to navigate, such as C:\.

  3. Restart computer and press F2 to enter BIOS. Select Advanced Mode (F7), go to Tool > ASUS EZ Flash 3 utility. Under Storage Device(s) locate your main drive (It's usually the biggest one). Navigate to the .CAP file and click YES/OK to confirm update.

The bios flashing last about 5 minutes. When the progress bar is completed, click OK to reboot. That's it.

Needless to say, this method will not work if your drive is encrypted or if you have older non-UEFI bios motherboard that doesn't have Flash 3 utility.

It works for me on my B550 mobo and Windows. Let me know if it works for you.
