ASUS Motherboard (B760M-PLUS) UEFI Boot Issue with Linux from USB Drive

Are you experiencing issues with booting Linux from a USB drive on your ASUS B760M-PLUS motherboard? You're not alone. Many users have encountered this problem, but don't worry - we're here to help you fix it.

The UEFI (Unified Extensible Firmware Interface) is responsible for initializing hardware components and loading the operating system. Sometimes, UEFI settings can interfere with the boot process, preventing Linux from being recognized on the USB drive. Let's go through the steps to resolve this issue.

Step 1: Update UEFI Firmware

It's essential to have the latest UEFI firmware installed on your ASUS B760M-PLUS motherboard. Manufacturers often release updates to fix bugs and improve compatibility. Follow these steps to update your UEFI firmware:

1. Visit the ASUS support website and navigate to the B760M-PLUS product page.
2. Download the latest UEFI firmware update for your motherboard model.
3. Save the firmware file to a USB drive formatted in FAT32.
4. Restart your computer and enter the UEFI settings by pressing the designated key during boot (usually Del or F2).
5. Navigate to the "Advanced" or "Tools" section and look for the "EZ Flash" or "Update BIOS" option.
6. Select the USB drive containing the firmware update file and follow the on-screen instructions to update the UEFI firmware.
7. After the update is complete, restart your computer and try booting Linux from the USB drive again.

Step 2: Configure UEFI Boot Options

If updating the UEFI firmware didn't resolve the issue, you may need to adjust the boot options in the UEFI settings. Follow these steps:

1. Restart your computer and enter the UEFI settings.
2. Navigate to the "Boot" or "Boot Options" section.
3. Ensure that the USB drive is listed as the first boot option. If not, use the arrow keys to move it to the top of the list.
4. Look for an option called "CSM" or "Compatibility Support Module" and enable it. This option allows UEFI to recognize legacy operating systems.
5. Save the changes and exit the UEFI settings.
6. Restart your computer and try booting Linux from the USB drive again.

Step 3: Check USB Drive and Linux Image

If the issue persists, there might be a problem with the USB drive or the Linux image you're using. Try the following troubleshooting steps:

1. Use a different USB drive: Sometimes, certain USB drives may not be compatible with UEFI systems. Try using a different USB drive and see if that resolves the issue.
2. Verify the Linux image: Ensure that the Linux image you downloaded is not corrupted. You can do this by checking the MD5 or SHA256 checksum provided by the Linux distribution's website.
3. Recreate the Linux bootable USB: Use a tool like Rufus or Etcher to recreate the Linux bootable USB drive. Make sure to select the correct options for UEFI booting.

By following these steps, you should be able to resolve the UEFI boot issue with Linux from a USB drive on your ASUS B760M-PLUS motherboard. If the problem persists, it's recommended to reach out to ASUS customer support for further assistance.
