Thanks for your very quick response -

The machines are legacy booting and secure boot is disabled.

My organization has 6 HP Compaq Pro 4300 SFF PC’s. For the past several years we’ve had no problem pushing images with FOG v0.32 via PXE boot to these machines. Early this year, we updated FOG to v1.2.0 and now these machines hang on PXE boot - the process starts and then hangs on the message ‘iPXE Initializing Devices’. There is no other text accompanying this message. We’ve tried several kernels, but we’ve yet to get these machines to download/upload FOG images via PXE. I’ve seen similar issues posted in the FOG forum, but we’re unable to find a solution.

Any advice would be greatly appreciated.
