WinPE Booting multiple operating systems

[NiKiZe]

you can modify (or add) the "startnet.cmd" file in the winpe image (do a internet search for startnet.cmd for lots of examples)

it is possible to use choice and other cmd things, or even running a .vbs script or similar instead or write your own program to display the menu.

I use a script that grabs the mac of the nic and posts that with wget to get a "next stage" cmd file dynamically, that way I can do settings in the ipxe menu which the winpe script then makes use of.
unfortunately it is currently not in a state which make it possible to share.

Please ask if anything is unclear or if you need further assistance.
