Setting Up a PXE Server for Windows 11 Boot

Are you trying to boot from a plain Windows 11 ISO or are you looking to deploy an image? If it’s the latter, consider the FOG Project. It’s a free, open-source solution that supports PXE boot setups with many customization options, although I haven’t tested it with 25H2 specifically.

Setting up a PXE boot server on Linux isn't too tough. However, installing Windows 11 via PXE might get tricky since Microsoft doesn’t officially support it. Essentially, you need to boot something that can write the right data to the target machine's drive and go from there. Typically, PXE systems boot the same OS they're installing, although they might lack some features initially.

You might want to check out netboot.xyz; it's quite helpful for PXE setups. If you're looking for a more hands-on approach, iPXE itself is worth exploring.

You could also look into the iPXE tool. A quick Google search will yield lots of guides for setting up a PXE server. It mainly involves running a TFTP server and a DHCP server to provide boot options. If your machines are modern, you can skip the TFTP server by setting option 67 to pull the iPXE binary from a web server.
