Hello @george1421, this is what I currently have under parameters:
kernel http://${fog-ip}/fog/images/wimboot
initrd http://${fog-ip}/fog/images/win7/boot/bcd
initrd http://${fog-ip}/fog/images/win7/boot/boot.sdi
initrd http://${fog-ip}/fog/images/win7/sources/boot.wim
boot
When I run this, it says OK after each one but then I get a black screen with a blinking cursor.
