This guide integrates U disk formatting and EFI BIOS flashing procedures. It is beginner-friendly. Follow the steps strictly to complete the BIOS update successfully.

Preparations

  1. Prepare a U disk (8G/16G is recommended for optimal compatibility);
  2. Back up all data on the U disk in advance; formatting will erase all files;
  3. Download the BIOS compressed file and save it to your computer desktop;
  4. Ensure stable power supply during the entire flashing process. For desktop computers, avoid power outages; for laptops, keep the power adapter connected.

Step 1: Format U Disk to FAT32 (Full Operation)

Windows Built-in Format Tool (For U Disks ≤32GB)

  1. Insert the U disk into the computer USB port and open This PC;
  2. Right-click the U disk drive letter and select Format;
  3. Set the formatting parameters as follows:

– File system: SelectFAT32

– Allocation unit size: Default size

– It is recommended to uncheck Quick Format for more stable BIOS flashing

  1. Click Start, confirm the pop-up warning, and wait for the formatting process to complete.

Step 2: Create BIOS Update U Disk

  1. Extract the downloaded BIOS compressed file to get the completeEFIfolder;
  2. Copy and paste the entire extracted EFI folderdirectly to the root directoryof the U disk (do not nest it in other folders or rename it);
  3. Confirm the EFI folder is directly displayed in the U disk root directory with correct file placement, then safely eject the U disk.

Step 3: Flash and Update Motherboard EFI BIOS

  1. Insert the prepared BIOS update U disk into the rear native USB port of the motherboard (USB2.0 port is preferred for better compatibility);
  2. Power on the computer and continuously press the F11key to call up the motherboard boot menu;
  3. Select the corresponding U disk boot option in the list and press Enter to enter the flashing program;
  4. Wait for the program to run and flash the BIOS automatically. Do not cut off power, unplug the U disk or operate the computer during the process;
  5. The prompt “FPT Operation Successful”indicates the BIOS flashing is completed;
  6. Restart the computer manually, enter the BIOS interface after booting, and check the BIOS version to confirm the update is successful.

Important Notes

  1. Do not use front chassis USB ports or low-quality U disks, which may cause recognition failure, flashing interruption or BIOS damage;
  2. The EFI folder must be placed in the U disk root directory. Do not modify or delete the folder name and internal files;
  3. Power interruption during flashing will cause BIOS damage and boot failure. Always ensure stable power supply;
  4. Do not restart or force shut down the computer before the success prompt appears to avoid process interruption.
