Ok.. Figured out that i need to run from ram.
In CdDrive -X: Y: , Check "Run ALL programs from RAM'. duh..

Pxe Boot Server Boot Loader file.
<PXE Boot TFTP Server Share>\grldr
<ex. \\192.168.1.30\PXE\grldr >
grub4dos settings
<PXE Boot TFTP Server Share>\menu.lst\default <<< "menu.lst" is a directory, "default" is a plain text file in Unix format <LF> only.
<ex. \\192.168.1.30\PXE\menu.lst\default >
menu.lst contents
timeout 5
default /default
title Win7PE SE (ISO)
map --mem (pd)/iso/Win7PESE_x86.ISO (0xff)
map --hook
root (0xff)
#pxe keep
chainloader (0xff)
boot
I put my ISO files into the <PXE Boot TFTP Server Share>\iso\ directory.
<ex. \\192.168.1.30\PXE\iso\Win7PESE_x86.ISO >
Hope this helps others that would like to boot an ISO from a PXE boot server..
I was able to get this to work with Win7PESE, but it failed on Win10PESE for some reason. I may investigate down the road if i am not able to complete my little build project.
My little project is trying to utilize WinxPESE as a limited RipBot264 distributed encoding server.
