Hi, try setting this parameter in /var/www/html/fog/service/ipxe/refind.conf: # Delay for the specified number of seconds before scanning disks. # This can help some users who find that some of their disks # (usually external or optical discs) aren't detected initially, # but are detected after pressing Esc. # The default is 0. # scan_delay 5 and, if you need, this: # Timeout in seconds for the main menu screen. Setting the timeout to 0 # disables automatic booting (i.e., no timeout). Setting it to -1 causes # an immediate boot to the default OS *UNLESS* a keypress is in the buffer # when rEFInd launches, in which case that keypress is interpreted as a # shortcut key. If no matching shortcut is found, rEFInd displays its # menu with no timeout. # timeout 5

@andrewg78 What I want you to do is start a new thread. I want you to pxe boot the target computer using FOG 1.5.4 and the post a clear screen shot of the exact error. Lets work through why its not working on your hardware there.
