Hello there
Based upon the information
Update motherboard firmware: Ensure that you have the latest firmware version installed on the motherboard. Visit Gigabyte's official website and download the latest BIOS update for your specific motherboard model. Follow the instructions provided by Gigabyte to perform the firmware update.
Verify UEFI settings: Double-check that the UEFI settings on the motherboard are correctly configured. Access the UEFI/BIOS setup utility by pressing a specific key (e.g., Del, F2, or Esc) during system startup. Confirm that the boot mode is set to UEFI and that the CSM (Compatibility Support Module) is disabled. Check other relevant settings, such as secure boot, network boot, and UEFI network stack.
Check DHCP configuration: Verify the DHCP configuration on the Cisco switch (3750) to ensure it is correctly configured for UEFI network boot. Confirm that the DHCP server is providing the necessary UEFI-related options, such as DHCP option 67 (Bootfile Name) and DHCP option 60 (Class Identifier). Ensure that the WDS server's IP address is correctly specified as the boot server in the DHCP configuration.
Check VLAN and subnet configurations: Verify that the VLAN configuration on the Cisco switch is correctly set up, and the DHCP scopes are appropriately configured for each VLAN/subnet. Ensure that the WDS server and the client machines are on the same VLAN and subnet.
And see if it helps,
Thank you
