@mardonis200 Looks like we have at least three different topics on this issue (links see below). As far as I get this an update to iPXE was causing this issue. You might want to try iPXE binaries from FOG 1.5.9. While this is not great it’s a start.

@mardonis200 Please try other physical machines. As well increase the kernel log level to 7 in the FOG settings (web UI).
