You can use netboot.xyz from a flash drive to boot various operating systems and utilities. Alternatively, PXE (Preboot Execution Environment) has been around for a while and works by allowing a network-capable device to boot from its network interface. A PXE-compatible network card requests a DHCP lease during the boot process, which provides the IP address of a TFTP (Trivial File Transfer Protocol) server and the file that needs to be loaded from the server.Typically, the network card contains a basic PXE kernel. To enhance this environment, you can chainload iPXE, which offers a broader range of features. iPXE allows for more advanced booting options, such as loading scripts or initiating an unattended installation directly from the network.
