What I did was get up a server as DHCP server on the LAN, install tftpd on it and have netboot.xyz on it. Then for other machines (inside same LAN) that you want to boot something or install a distro, you would boot LAN, the dhcp server you set up will automatically let that other machine boot into netboot.xyz and then you can choose your distro.

It works really well for colocation server where you don't have the freedom to go there and plug in an Usb or a DVD because it's 1000km away in the footsteps of a hotspring in Iceland for example.
