Often, you just copy the BIOS file to the root of the FAT32-formatted flashdrive, boot into the BIOS, and then press the function key associated with BIOS Update. For example, F7 is a popular choice for BIOS Upgrades with AMI; but confirm that by going into the BIOS, and then look on the bottom of the screen and see if F7 is listed there for BIOS UPDATE.

If it is, power down, then insert the flash drive with the file for the update, and get into the BIOS, then press F7 and choose the BIOS file to use for the update.

[Motherboard] How to update BIOS?
Can I update my motherboard's BIOS from inside Microsoft Windows (@BIOS, Live Update, etc.) or should I use the UEFI tools only?
You could update in Windows, but it is safer to use the UEFI tools: ASUS EZ Flash, MSI M-Flash, GIGABYTE Q-Flash, ASRock Instant Flash. Windows crashes and background processes add risk. Use a Windows-only EXE method only if the manufacturer explicitly requires it.

Why does my PC restart, but the BIOS update never installs?
This usually means the update didn’t copy to the system firmware correctly. Try running the update tool again as an Administrator. If it still fails, check if your antivirus or BitLocker encryption is blocking the update. Temporarily disabling these often solves this type of problem.

r/techsupport on Reddit: How to update my AMI BIOS?
November 12, 2025 -

Okay. I give up. Event viewer occasionally says Secure Boot CA/keys need to be updated. For other reasons it seemed like the BIOS needed to be updated but it was a hassle so I put it off. But I have no idea which exact utility and variant I need to use to update my BIOS. Sure, we are told to download the correct update file from your computer or motherboard manufacturer's website and etc but it isn't always clear to the ignorant such as myself which is the correct update file and/or utility.

November 8, 2024 - As you know, the procedure is to download the most recent BIOS from the manufacturer, then copy the CAP file and the Microsoft Windows 'renamer' executable to the root of the USB stick, use the renamer to rename the CAP file - and likely do something else to the CAP file - then go back into BIOS, where - in my case - the ASUS EZ Bios Update utility recognizes the now-renamed CAP file and updates the BIOS.
