Which setting must be enabled for a server to boot using PXE in UEFI mode?

To enable a server to boot using PXE (Preboot Execution Environment) in UEFI mode, the UEFI Boot Mode setting must be enabled. This setting allows the firmware to utilize the UEFI specification, which is necessary for network booting in this particular mode. UEFI offers a more modern approach to booting compared to Legacy Boot, as it supports larger boot drives and provides a more flexible and efficient boot environment.

When UEFI Boot Mode is enabled, the server is equipped to load the operating system from a network instead of from a local drive, which is essential when using PXE. This is particularly important in environments where centralized management and deployment of operating systems are required.

In addition, for a successful PXE boot operation in UEFI, other factors such as network configurations and the presence of a PXE server must also be set correctly, but the primary requirement for the server itself to recognize and begin the PXE boot process is the UEFI Boot Mode setting.
