@george1421 So the second part of this is; I would create a custom FOG iPXE menu item to test this next bit. Since refind exists in the http path we can use the http protocol to grab the files you need.
I would start out by cloning the FOG provided refind.conf file to… for this example refind2.conf. Place any files you want to load in the http path on the fog server but not in the fog file path because an upgrade will delete your custom files. For this example lets create a new directory with
mkdir /var/www/html/crefind place your cloned refind2.conf file in there plus any other files you want to load onto the refind vhd.
set http-path http://${fog-ip}
set custrefind-path ${http-path}/crefind
set refind-path ${http-path}/forg/service/ipxe
kernel ${refind-path}/refind_x64.efi
imgfetch --name refind.conf ${custrefind-path}/refind2.conf refind.conf
imgfetch --name os_linux.png ${custrefind-path}/os_linux.png os_linux.png
imgfetch --name theme.conf ${custrefind-path}/theme.conf theme.conf
boot || goto MENU
Understand I did not debug this menu at all, I just glued the bits together. So it might work or might now. But the idea is correct. Remember in your refind2.conf file the ipxe vhd has no paths so everything is stored in the root of the vhd. So this config file stanza
icon /EFI/refind/themes/rEFInd-minimal-drunkcj/icons/os_linux.png
Needs to be rewritten as
icon os_linux.png
