netbooting winbuilder WINPE 7 ISO

  • Hopefully this helps some others. Through a tremendous amount of trial and error, I was able to netboot/IPXE boot an ISO created using winbuilder from You can build a WINPE 7 (or 10) using the plugins and WINBUILDER from THEOVEN.ORG. Tha advantage is that it can include a very large amount of apps like antivirus or several different disk imaging packages. Be sure that you configure the plugins to “RUN from RAM” so that they are included in the BOOT.WIM when building. Also, because the BOOT.WIM can be much larger than normal depending on the drivers and apps included, the system you are netbooting/IPXE booting from will need a large amount of memory. This is my MENU entry for booting an unpacked ISO built using winbuilder.
