For my non-profit I have set-up a fog server and it works great except for a couple of things.
Whenever I set a custom background for the pxe menu, the colors revert back to black/red and no image. (See picture).
When I use the settings -> ipxe menu settings -> name of file.png it displays the red/black screen. But bg.png works.
I’ve copied the image to the same folder as the bg.png (/downloads/fogproject-1.5.5/packages/web/service/ipxe)
Also, sometimes when I image a image with our general win 10 uefi image, it does not apply the windows boot manager. If you add it manually in the bios, then it loads fine. This is not on all systems, but mostly dell ones.
