The client computer has windows 10 version 1809, build 17763.557
The FOG server is a 32-bit Ubuntu 16.04 with Fog version 1.5.6
I changed Windows 10 to legacy boot mode to access the boot process
I was able to register the client machine with the FOG server, which shows they can communicate without a problem.
When the client machine is started, the pxe initiates normally and, when it sees there are no FOG commands, the white menu box appears with the default highlighted command being to boot from the hard drive, just like it normally does. The problem is that a black screen appears with a blinking cursor and remains indefinitely. There is no boot to the hard drive. If I boot and manually cancel the pxe boot with a keystroke, it has no problem booting from the hard drive. The problem seems to be with FOG correctly accessing the hard drive from its boot menu. Any ideas what to do?
